Strategic Implications of the Extension of the U.S. National Emergency Against North Korea and the Strengthening of ROK-U.S.-Japan Cyber Cooperation
Executive Summary
Executive Summary
The extension of the U.S. national emergency against North Korea is an institutional mechanism that has been in place for over 30 years. By maintaining this measure, the second Trump administration is continuing a dual approach that preserves the legal basis of the sanctions regime while not completely blocking diplomatic flexibility. However, as North Korea's nuclear capabilities are expanding into multiple domains, with Kim Jong Un enshrining the status of a nuclear-weapon state in the constitution and declaring the creation of a nuclear-armed navy, it is structurally difficult for negotiations based on the premise of complete denuclearization in the traditional sense to achieve results in the short term. The possibility of the Trump administration's diplomatic confidence, following the resolution of the Iran nuclear deal, spilling over into the North Korean nuclear issue, combined with the Lee Jae-myung administration's request for a resumption of dialogue, makes the prospect of a renewed North Korea-U.S. summit realistic. However, the outcome is likely to be an interim agreement in the form of a nuclear freeze or arms control, rather than denuclearization. Meanwhile, as North Korea has structured cybercrime as a core national strategy for funding its nuclear development, the institutionalization of trilateral cyber cooperation among South Korea, the U.S., and Japan is assessed as a strategic asset that should be sustained and deepened, regardless of changes in the diplomatic landscape. Accordingly, this report recommends a dual-track strategy of simultaneously pursuing sanctions/deterrence maintenance and phased diplomacy as a core response, and proposes an action plan centered on four pillars: deepening cyber cooperation, strengthening the credibility of extended deterrence, preparing a phased incentive package based on a nuclear freeze, and multi-layered expansion of trilateral cooperation among South Korea, the U.S., and Japan.
Phase 1: Issue Situation Analysis
Extension of the U.S. National Emergency Against North Korea and Strengthening of ROK-U.S.-Japan Cyber Cooperation: Issue Situation Analysis
1. Background and Progress of the Issue
The U.S. declaration of a national emergency against North Korea, first invoked in 1994 during the Clinton administration in response to the threat of North Korea's nuclear development, has been an institutional mechanism renewed annually by successive administrations. This declaration serves as the legal basis for the U.S. to define North Korea as an 'unusual and extraordinary threat' and provides the administrative foundation for sanctions against North Korea. The second Trump administration has maintained this stance, extending the declaration for another year in 2026, confirming its continued dual approach of preserving the sanctions regime while leaving room for diplomatic engagement.
North Korea's nuclear and missile capabilities have significantly advanced in both quality and quantity during this period. Kim Jong Un officially declared the consolidation of nuclear-weapon state status, setting a goal of "nuclear power that overwhelms the world" at a plenary meeting of the Workers' Party of Korea [5], and publicly demonstrated the capability to strike South Korean power facilities using tactical nuclear missiles [10]. Furthermore, by declaring plans to create a nuclear-armed navy and expressing intent to build a 10,000-ton warship [14][17], North Korea is actively pursuing the expansion of its nuclear capabilities into multiple domains. These actions by North Korea imply a strategic intent to solidify its international status as a nuclear-weapon state, going beyond mere deterrence maintenance.
Meanwhile, as the proportion of cybercrime in North Korea's funding for nuclear development has rapidly increased, cybersecurity has emerged as a key front for the implementation of sanctions against North Korea. According to reports from UN expert panels, North Korea-linked hacking groups have raised hundreds of millions of dollars annually through various methods such as cryptocurrency theft, infiltration of financial institutions, and disguised employment of IT personnel, serving as a crucial channel to circumvent international sanctions. In response, South Korea, the U.S., and Japan have been operating a trilateral working group on cyber threats since 2023, and during the 5th meeting, they deepened discussions on law enforcement cooperation and strengthening sanctions implementation.
2. Current Situation (Latest Trends)
The current Korean Peninsula security environment is characterized by a complex tension where North Korea's advancement of nuclear capabilities and the strengthening of ROK-U.S.-Japan cooperation are occurring simultaneously. At a recent plenary meeting of the Workers' Party of Korea, North Korea strongly criticized South Korea's pursuit of nuclear-powered submarines, framing it as a 'nuclear threat from South Korea and the U.S.' in conjunction with the ROK-U.S. Nuclear Consultative Group (NCG) [5][6]. Kim Jong Un reaffirmed South Korea as the 'most hostile country' and is using this to justify measures of severance with the South, such as armament along the Military Demarcation Line [5].
In the U.S., amidst growing diplomatic interest in resolving the North Korean nuclear issue following the conclusion of the Iran nuclear deal, President Lee Jae-myung has reportedly directly requested President Trump to seek a diplomatic resolution to the North Korean nuclear problem [15]. This suggests that the new South Korean administration is placing weight on the possibility of resuming dialogue, while also reflecting the increasing attention from the international community on whether the Trump administration will resume diplomatic engagement with North Korea. However, the U.S. is moving towards consolidating the sanctions regime, such as extending the national emergency and strengthening export controls on dual-use items, including medical devices [4], indicating a continued dual approach of diplomacy and pressure.
In the field of cybersecurity, trilateral cooperation among South Korea, the U.S., and Japan is entering an institutionalization phase. The 5th working group meeting addressed not only information sharing but also law enforcement cooperation and strengthening sanctions implementation mechanisms, demonstrating the evolving approach to cyber threats from North Korea towards an integrated strategy of diplomacy, security, and law enforcement. Furthermore, the trend of expanding multilateral cooperation frameworks for cybersecurity, such as the Five Eyes alliance issuing joint warnings on AI-based cyber threats [6][11], is creating a favorable environment for enhancing capabilities to counter North Korean cyber threats.
Militarily, South Korea has announced plans to comprehensively overhaul its drone operational capabilities, strengthening its asymmetric response capabilities against North Korea's drone threats [8]. North Korea continues construction activities of a civilian nature near the DMZ, but the UN Command has stated that it does not consider these violations of the Armistice Agreement [12].
3. Key Actors and Their Positions/Interests
United States (Trump Administration)is maintaining the legal basis of the sanctions regime through the extension of the national emergency against North Korea, while also exploring the possibility of applying the diplomatic momentum from the Iran nuclear deal resolution to the North Korean nuclear issue. Given that President Trump directly pursued North Korea-U.S. summits during his first term, there is an incentive to seek a diplomatic breakthrough through a 'grand bargain' in his second term as well. However, the current strategy is one of strategic patience, maintaining the sanctions regime and ROK-U.S.-Japan cooperation to build negotiating leverage. The core U.S. interest lies in preventing North Korea's nuclear and missile capabilities from advancing to a level that threatens the U.S. homeland and maintaining the credibility of the East Asian alliance system.
North Korea (Kim Jong Un Regime)is consistently pursuing a strategy of establishing its status as a nuclear-weapon state as a fait accompli, rather than a subject for negotiation. Kim Jong Un firmly rejects demands for denuclearization [1], and has formalized the strengthening of nuclear capabilities as 'the only way to respond to the uncertainties of the global security environment' [7]. The creation of a nuclear-armed navy [14][17], testing of tactical nuclear capabilities [10], and funding through cyberattacks are all components of this strategy. North Korea's core interest is regime survival and the perpetuation of the Kim Jong Un regime, with nuclear capabilities serving as the ultimate safeguard. Simultaneously, it seeks to legitimize its nuclear development domestically and internationally by framing ROK-U.S. military cooperation as a 'nuclear war threat' [9].
South Korea (Lee Jae-myung Administration)faces the dual challenge of strengthening deterrence against North Korean nuclear threats and seeking a diplomatic resolution. Strengthening extended deterrence through the ROK-U.S. NCG [5][9] and pursuing the acquisition of nuclear-powered submarines are responses in terms of deterrence, while President Lee Jae-myung's request to President Trump for a diplomatic resolution of the North Korean nuclear issue [15] reflects a desire to resume dialogue. South Korea's core interest lies in ensuring security from North Korean nuclear threats and minimizing economic uncertainty arising from heightened tensions on the Korean Peninsula. The reaffirmation of the historical foundation of the ROK-U.S. alliance on the occasion of the 76th anniversary of the Korean War through the U.S. Embassy in Seoul [13] can also be understood in this context.
Japanis an key partner in strengthening trilateral cyber cooperation among South Korea, the U.S., and Japan, and is actively engaged in joint responses to North Korean cyberattacks and nuclear/missile threats. Japan's interests lie in securing direct security from North Korean ballistic missile threats and strengthening its regional security role through trilateral security cooperation frameworks among South Korea, the U.S., and Japan.
Chinais not directly involved as an actor in this issue, but Kim Jong Un's affirmation of support for the 'One China' principle during Xi Jinping's visit to Pyongyang [9] suggests strengthening strategic ties between North Korea and China. China maintains a dual stance, theoretically supporting denuclearization of the Korean Peninsula while prioritizing the stability of the North Korean regime, and tends to respond passively to U.S.-led strengthening of sanctions against North Korea.
4. Summary of Key Issues
First, the fundamental gap between denuclearization and recognition of nuclear-weapon state status is the most critical issue. The U.S. and South Korea maintain denuclearization of North Korea as the ultimate goal of negotiations [9], while North Korea has declared its status as a nuclear-weapon state as an unnegotiable fait accompli, rejecting demands for denuclearization itself [1][7]. Unless this gap is resolved, the resumption of substantive diplomatic negotiations will inevitably face structural limitations.The fundamental gap between denuclearization and recognition of nuclear-weapon state statusis the core issue. While the United States and South Korea maintain North Korean denuclearization as the ultimate goal of negotiations [9], North Korea has declared its status as a nuclear-weapon state as a non-negotiable fait accompli, rejecting the demand for denuclearization itself [1][7]. Unless this gap is resolved, the resumption of substantive diplomatic negotiations will inevitably face structural limitations.
Second, the resumption and conditions of North Korea-U.S. diplomacy by the Trump administration are emerging as important issues. While there are expectations that the resolution of the Iran nuclear deal could serve as a catalyst for the resumption of North Korea-U.S. dialogue [15], North Korea has shown willingness to negotiate only on the premise of its status as a nuclear-weapon state, making the conditions set by the U.S. for entering negotiations crucial. It remains to be seen whether Trump's unique style of summit diplomacy can break this deadlock.The resumption and conditions of engagement with North Korea under the Trump administrationare emerging as important issues. While there are expectations that the conclusion of the Iran nuclear deal could serve as a catalyst for the resumption of US-North Korea dialogue [15], North Korea has shown willingness to negotiate only on the premise of its nuclear-weapon state status, making the conditions set by the US for entering negotiations the key factor. Attention is focused on whether Trump's unique summit diplomacy approach can break this deadlock.
Third, the issue of the effectiveness of sanctions implementation against North Korea in cyberspace. As North Korea solidifies its structure of funding nuclear development by circumventing sanctions through cybercrime, the question is whether trilateral cooperation among South Korea, the U.S., and Japan can acquire the capabilities to effectively block this. The rapid evolution of AI-based cyber threats [6][11] further complicates this challenge.Effectiveness of sanctions against North Korea in cyberspaceis a problem. As North Korea's structure of circumventing sanctions through cybercrime to fund its nuclear development becomes entrenched, the issue is whether the US-South Korea-Japan trilateral cooperation can acquire the capacity to effectively block this. The rapid evolution of AI-based cyber threats [6][11] further complicates this challenge.
Fourth, the sustainability of trilateral security cooperation among South Korea, the U.S., and Japan. Trilateral cooperation among South Korea, the U.S., and Japan is being institutionalized as a key framework for responding to North Korea's nuclear threat, but historical conflicts between South Korea and Japan and domestic political variables can act as constraints on the stability of this cooperation. In particular, how the new South Korean administration's North Korea policy will be coordinated with the trilateral cooperation framework will be a significant variable going forward.Sustainability of trilateral security cooperation among South Korea, the United States, and Japanis at stake. While trilateral cooperation among South Korea, the United States, and Japan is being institutionalized as a core framework for responding to North Korea's nuclear program, historical conflicts between South Korea and Japan and domestic political variables can act as constraints on the stability of this cooperation. In particular, how the new South Korean government's North Korea policy aligns with the trilateral cooperation framework will be a significant variable going forward.
Fifth, the change in the deterrence structure due to the multi-domain expansion of North Korea's nuclear capabilities. The simultaneous advancement of tactical nuclear capabilities [10], a nuclear-armed navy [14][17], and cyber capabilities complicates existing deterrence calculations and poses new challenges to maintaining the credibility of the extended deterrence system between South Korea and the U.S.Changes in the deterrence structure due to North Korea's multi-domain expansion of nuclear capabilitiesare occurring. The simultaneous advancement of tactical nuclear capabilities [10], a nuclear-armed navy [14][17], and cyber warfare capabilities complicates existing deterrence calculations and poses new challenges to maintaining the credibility of the US-South Korea extended deterrence system.
Phase 2: In-depth Issue Analysis
Extension of the U.S. National Emergency Against North Korea and Strengthening of ROK-U.S.-Japan Cyber Cooperation: In-depth Issue Analysis
1. Analysis of the Root Causes of the Issue
The root cause of this issue stems from North Korea's strategic choice to internalize nuclear weapons as an absolute guarantee of regime survival. North Korea has deeply internalized the historical lesson that regimes like Libya's Gaddafi and Iraq's Hussein collapsed after abandoning their nuclear/weapons of mass destruction, and from this, has firmly established the equation that nuclear abandonment is equivalent to regime demise. Kim Jong Un's public declaration at a plenary meeting of the Workers' Party of Korea of a goal of 'nuclear power that overwhelms the world' [5] and the enshrining of nuclear-weapon state status in the constitution signify that this strategic choice has been institutionalized to a point of no return.
Coupled with this, the change in the funding structure that sustains North Korea's nuclear development serves as a second root cause. As international sanctions intensify, North Korea has developed cybercrime as a core alternative means, as traditional foreign exchange sources such as mineral exports and dispatched labor have been blocked. Sophisticated cybercrime methods, including cryptocurrency theft, hacking of financial institutions, and disguised employment of IT personnel, exploit structural loopholes in the existing sanctions regime by circumventing both physical borders and sanctions networks. This functions not merely as criminal activity but as part of a national strategy for funding nuclear development, which is why the trilateral cooperation among South Korea, the U.S., and Japan has elevated cyber cooperation to a key front for sanctions implementation.
A third root cause lies in the structural contradictions within the U.S. approach to North Korea. On one hand, the U.S. maintains and strengthens the sanctions regime through measures such as extending the national emergency and enhancing export controls on medical devices [4]. On the other hand, following the resolution of the Iran nuclear deal, it maintains a dual stance that does not entirely rule out the possibility of resuming diplomatic engagement on the North Korean nuclear issue. This contradiction arises from the gap between the realistic recognition that sanctions alone cannot lead to North Korea's denuclearization and the dilemma that lifting sanctions would result in the loss of negotiating leverage. The situation where President Lee Jae-myung has reportedly directly requested President Trump to seek a diplomatic resolution to the North Korean nuclear problem [15] indicates that this structural contradiction is also recognized within the ROK-U.S. alliance.
2. Structural Context
Political Structure
At the political level, this issue is situated within a complex structure where U.S. domestic politics and East Asian regional politics intersect. The national emergency against North Korea in the U.S. is an institutional mechanism based on bipartisan consensus, and the second Trump administration, by extending it, maintains the legal and administrative foundation for a hardline stance against North Korea. Concurrently, President Trump's precedent of direct North Korea-U.S. summits or meetings three times during his first term means that tension between maintaining sanctions and resuming dialogue persists within the administration.
At the regional political level, the emergence of the new South Korean administration is a significant variable. The Lee Jae-myung administration holds a more proactive stance on resuming dialogue, which could create subtle differences in approach between South Korea and the U.S. regarding North Korea. In contrast, North Korea has designated South Korea as the 'most hostile country' [5][6] and is continuing armament along the Military Demarcation Line, strengthening its policy of severance with the South, thus severely limiting the space for inter-Korean dialogue at present. Furthermore, Kim Jong Un's reported affirmation of China's 'One China' principle regarding Taiwan during Chinese President Xi Jinping's visit to Pyongyang [9] confirms that North Korea is reorganizing its diplomatic axis towards strengthening strategic ties with China and Russia.
Economic Structure
Economically, the core of this issue lies in the structural problem of weakening sanctions effectiveness and North Korea's establishment of a self-reliant nuclear economy. As international sanctions intensify, North Korea has developed new channels to circumvent them, with cybercrime being the most sophisticated form. The growth of the cryptocurrency market and the expansion of the decentralized finance (DeFi) ecosystem provide North Korean hacking groups with hard-to-trace money laundering channels, fundamentally eroding the effectiveness of traditional financial sanctions. The call by South Korea, the U.S., and Japan during the 5th trilateral working group meeting on cyber threats to strengthen law enforcement cooperation and sanctions implementation is an attempt to close this economic loophole, but complete blockage is structurally difficult due to technological asymmetry and limitations in international cooperation.
Furthermore, the US tightening of medical device export restrictions[4] is an attempt to block North Korea's acquisition routes for dual-use equipment, but it also acts as a double-edged sword, provoking humanitarian concerns. This is a case that simultaneously demonstrates the efforts to enhance the precision of sanctions (smart sanctions) and their limitations.
Security Structure
The most notable structural change from a security perspective is the evolution of North Korea's nuclear capabilities from deterrence to coercion. North Korea is actively pursuing a multi-domain, multi-layered expansion of its nuclear capabilities, as evidenced by its public testing of capabilities to strike power facilities within South Korea using tactical nuclear missiles[10], and its declaration of establishing a nuclear-armed navy with plans to build 10,000-ton warships[14][17]. This suggests a shift towards a nuclear coercion strategy that goes beyond maintaining strategic deterrence, aiming to constrain the actions of adversaries through the threat of nuclear use even in conventional conflict situations.
In response, South Korea and the US are continuously strengthening extended deterrence through the 6th Nuclear Consultative Group (NCG) meeting[5][6][9], and South Korea is enhancing its asymmetric response capabilities by comprehensively reforming its drone forces[8]. However, North Korea frames the NCG itself as a "nuclear war organization" and uses it as a rationale to justify its own nuclear capability buildup[9], thereby intensifying the security dilemma between strengthening deterrence and escalating tensions.
3. Comparison of Historical Precedents and Similar Cases
The Geneva Agreed Framework of 1994 and its Collapse
The historical starting point of the North Korean nuclear issue is the 1994 Agreed Framework. At that time, the Clinton administration reached a comprehensive agreement promising light-water reactors and heavy fuel oil in exchange for North Korea's nuclear freeze. The declaration of a state of national emergency regarding North Korea was invoked for the first time as a legal response to this agreement. However, the agreement effectively collapsed in 2002 due to a lack of implementation will and mutual distrust from both sides, as well as political opposition within the United States. This precedent left the lesson that the robustness of the implementation mechanism is more important than the conclusion of the agreement itself, and it suggests that whatever form of North Korea-US agreement the current second Trump administration pursues, this lesson will inevitably be reflected in the negotiation design.
The Six-Party Talks Framework (2003-2009) and the Limits of Denuclearization Agreements
The Six-Party Talks, held from 2003 to 2009, were the most comprehensive attempt to resolve the North Korean nuclear issue within a multilateral framework. Although an agreement on the principle of North Korea's denuclearization was reached through the September 19 Joint Statement in 2005, the talks ultimately broke down due to issues surrounding the sanctions on Banco Delta Asia (BDA), conflicts over the timing of light-water reactor provision, and North Korea's second nuclear test in 2009. This precedent demonstrated the limitations of multilateral diplomacy in controlling North Korea's tactical flexibility and subsequently led the US to shift towards a bilateral direct dialogue approach.
The Trump Administration's First North Korea-US Summits (2018-2019) and the Hanoi Collapse
The North Korea-US summit diplomacy of the first Trump administration is the historical precedent most directly comparable to the current situation. While a principled agreement on "complete denuclearization" was reached at the Singapore Summit in 2018, the Hanoi Summit in 2019 collapsed without an agreement due to fundamental differences in positions regarding the scope of denuclearization and the level of sanctions relief. North Korea demanded comprehensive sanctions relief in exchange for the dismantling of the Yongbyon nuclear facility, while the US demanded broader denuclearization measures, including facilities beyond Yongbyon. This precedent serves as a reminder that even if the current second Trump administration resumes North Korea-US dialogue, the fundamental differences in positions identified at Hanoi may still remain unresolved. Furthermore, given that North Korea has significantly advanced its nuclear capabilities since Hanoi, the demands from North Korea are likely to be considerably higher if negotiations resume.
Comparison with the Iran Nuclear Deal (JCPOA)
The Iran nuclear deal is emerging as an important reference case for current North Korean nuclear diplomacy. The situation where President Lee Jae-myung reportedly requested President Trump for a similar diplomatic resolution of the North Korean nuclear issue after the conclusion of the Iran nuclear deal[15] illustrates the influence of the Iran model on North Korean nuclear diplomacy. However, there are critical differences between Iran and North Korea. Iran accepted an agreement that limited its nuclear development capabilities while not actually possessing nuclear weapons, whereas North Korea, already a significant nuclear power, does not even recognize denuclearization itself as a subject for negotiation[1]. North Korea's Ministry of Foreign Affairs has clarified this through a series of recent statements urging denuclearization, reaffirming its status as a nuclear-weapon state[1].
4. Key Variables in Issue Development
The first key variable determining the future development of the issue is the Trump administration's willingness and method for resuming North Korea diplomacy. Former President Trump has a precedent of approaching the North Korean nuclear issue through personal diplomacy between leaders during his first term, and interest in a diplomatic resolution of the North Korean nuclear issue has been growing following the conclusion of the Iran nuclear deal[15]. Whether the Trump administration will opt for a modified form of "maximum pressure and engagement," combining continued sanctions with renewed diplomacy, or focus solely on strengthening sanctions will be a key turning point in the short-term development of the issue.
The second key variable is a change in North Korea's strategic calculations. Currently, North Korea is focused on enhancing its capabilities to solidify its status as a nuclear-weapon state and maintains a position of rejecting denuclearization negotiations[1]. However, it is not entirely impossible that North Korea may selectively engage in resuming negotiations in response to intensified economic pressure or changes in the strategic environment. In particular, the direction of the Russia-Ukraine war and the continuation of military cooperation between Russia and North Korea will act as external variables influencing North Korea's strategic autonomy[9].
The third key variable is the sustainability and internal cohesion of the South Korea-US-Japan trilateral cooperation. The effectiveness of pressure on North Korea may vary depending on how closely the South Korean government's approach to North Korea is coordinated with that of the US and Japan. If South Korea seeks to broaden its independent diplomatic space by emphasizing the resumption of dialogue, cracks may emerge in the internal cohesion of South Korea-US-Japan cooperation, which could provide an incentive for North Korea to intensify its tactical attempts to drive a wedge between South Korea and the US.
The fourth key variable is the competition for technological superiority in cyberspace. As the heads of Five Eyes cybersecurity agencies have warned that AI is reshaping cyber risks on a timescale of months rather than years[6][11], the advancement of AI technology is a dual variable affecting both North Korea's cyberattack capabilities and the defense capabilities of South Korea, the US, and Japan. If North Korea enhances its AI-powered cyberattack capabilities, the question of whether the current trilateral cooperation framework can maintain sufficient technological responsiveness will emerge as a key medium-to-long-term variable. This poses a structural challenge that requires not only simple law enforcement cooperation but also the advancement of technology standard sharing and real-time information exchange systems.
Phase 4: Analysis of Response Measures
Extension of US State of National Emergency on North Korea and Strengthening of South Korea-US-Japan Cyber Cooperation: Analysis of Response Measures
1. Presentation of Response Options by Scenario
The main scenarios derived from the previous analysis can be broadly categorized into three. First, a scenario involving the resumption of North Korea-US diplomacy and the successful conclusion of a summit. Second, a scenario of strengthening sanctions and pressure while maintaining the status quo. Third, a scenario of accelerating North Korea's nuclear capability buildup and escalating tensions on the Korean Peninsula. These scenarios are not mutually exclusive, and it is highly likely that a mixture of scenarios will emerge in the short term. Below, specific response options for the US, South Korea, and the trilateral South Korea-US-Japan framework are presented for each scenario.
Scenario 1: Resumption of North Korea-US Diplomacy and Successful Summit
This scenario assumes a situation where President Trump extends the diplomatic momentum from the conclusion of the Iran nuclear deal to the North Korean nuclear issue, and direct contact between North Korea and the US resumes in response to the South Korean government's request for renewed dialogue[15]. In this case, the response options available to the US can be summarized as follows.
Option 1-A: Presentation of a comprehensive negotiation package with phased sanctions relief as a prerequisite.This approach involves the US presenting a package of incentives, such as expanded humanitarian assistance, the opening of liaison offices, and partial sanctions relief, in exchange for North Korea's nuclear freeze or partial denuclearization measures. This is an approach closer to a "small deal" than a "big deal," based on the principle of phased reciprocity.
Option 1-B: Freeze-for-Freeze Approach.This involves the US reducing or temporarily suspending joint South Korea-US military exercises in exchange for North Korea halting further nuclear tests and intercontinental ballistic missile (ICBM) test launches. This option could be discussed as an extension of the Singapore agreement during the first Trump administration.
Option 1-C: Transition to Arms Control Negotiations with De Facto Recognition of Nuclear Status.This approach involves shifting the framework to arms control negotiations, based on the premise of de facto recognizing North Korea as a nuclear-weapon state, without insisting on denuclearization as a prerequisite. This is a radical option that conflicts with the existing joint goal of "complete denuclearization" but is a choice discussed from a realist perspective[1][7].
Scenario 2: Maintaining the Status Quo While Strengthening Sanctions and Pressure
This scenario assumes a situation where there is no diplomatic breakthrough between North Korea and the US, and the US maintains its current policy of combining sanctions with strengthened deterrence. The extension of the state of national emergency and the tightening of medical device export restrictions[4] are typical measures in this scenario.
Option 2-A: Deepening Cyber Sanctions and Law Enforcement Cooperation.This approach involves pursuing additional sanctions against North Korea-linked hacking groups, strengthening regulations on cryptocurrency exchanges, and freezing proceeds from cybercrimes, primarily through the South Korea-US-Japan trilateral cyber threat diplomatic working group. This is directly linked to the direction discussed in the 5th meeting.
Option 2-B: Strengthening Extended Deterrence and Enhancing NCG Operations.This approach aims to enhance deterrence against North Korea by deepening the sharing of nuclear plans through the South Korea-US Nuclear Consultative Group (NCG), increasing the frequency of strategic asset deployments, and supporting South Korea's strengthening of independent conventional deterrence capabilities[6][9]. It also includes strengthening asymmetric deterrence capabilities in conjunction with South Korea's drone force expansion plans[8].
Option 2-C: Strengthening Implementation of Multilateral Sanctions and Blocking Sanctions Evasion.This approach systematically blocks North Korea's sources of foreign currency income by strengthening the monitoring of UN Security Council sanctions implementation, blocking sanctions evasion through third countries, and identifying and sanctioning North Korean IT personnel working abroad.
Scenario 3: Accelerating North Korea's Nuclear Capability Buildup and Escalating Tensions on the Korean Peninsula
This scenario assumes a situation where North Korea drastically escalates its provocations, such as conducting a 7th nuclear test or resuming ICBM test launches. Kim Jong Un's declaration of establishing a nuclear-armed navy[14][17] and his display of capabilities to strike South Korean power facilities with tactical nuclear missiles[10] are interpreted as signals that increase the likelihood of this scenario's realization.
Option 3-A: Urgent Convening of the UN Security Council and Pursuit of Additional Sanctions Resolutions.This approach involves urgently convening the UN Security Council and pursuing additional sanctions resolutions in the event of a North Korean nuclear test or ICBM launch. However, the effectiveness is limited due to the possibility of vetoes from China and Russia.
Option 3-B: Expanding Unilateral Sanctions and Strengthening Secondary Boycotts.This approach involves the US expanding unilateral sanctions and strengthening secondary boycotts against third-country companies and financial institutions dealing with North Korea to compensate for the limitations of UN sanctions. It includes measures to strengthen crackdowns on Chinese companies violating sanctions against North Korea.
Option 3-C: Strengthening South Korea-US-Japan Military Cooperation and Constant Deployment of Strategic Assets.In the event of escalating tensions on the Korean Peninsula, this approach involves significantly increasing the frequency and scale of strategic asset deployments, such as US strategic bombers, nuclear-powered aircraft carriers, and nuclear-powered submarines, to the Korean Peninsula, and strengthening military information sharing and joint exercises among South Korea, the US, and Japan[9].
2. Analysis of Pros and Cons of Each Response Option
Options Related to Scenario 1
Option 1-A (Comprehensive Negotiation Package)The greatest advantage of this option is that it provides a realistic possibility for a diplomatic breakthrough. The principle of phased reciprocity offers justification for both sides, and its timeliness allows for leveraging the diplomatic momentum from the conclusion of the Iran nuclear deal. However, there is a risk that North Korea may employ a "salami tactic" by using the nuclear freeze as a bargaining chip while delaying substantive denuclearization measures. Paradoxically, sanctions relief could also increase its capacity to fund nuclear development. In terms of alliance management with South Korea and Japan, if the US proceeds with negotiations without sufficient consultation with its allies, cracks may emerge in the South Korea-US-Japan cooperation framework.
Option 1-B (Freeze-for-Freeze Approach)has the advantage of potentially easing tensions on the Korean Peninsula and deterring further provocations in the short term. It aligns with President Trump's transactional diplomacy style and is a relatively feasible option. On the other hand, the reduction of joint South Korea-US military exercises raises concerns about weakening South Korea's defense posture, and it cannot be ruled out that North Korea may use the freeze period to advance its nuclear capabilities. Given that North Korea has already enshrined its status as a nuclear-weapon state in its constitution and declared its goal of "nuclear power that will overwhelm the world"[5], there is a structural limitation in securing a path from a freeze agreement to denuclearization.
Option 1-C (Transition to Arms Control Negotiations)offers the practical advantage of limiting North Korea's nuclear capabilities to a manageable level from a realist perspective. However, this option is highly likely to provoke strong opposition from South Korea and Japan, and it carries the serious disadvantage of setting a precedent that undermines the foundation of the Nuclear Non-Proliferation Treaty (NPT). In particular, it could act as a catalyst for discussions on independent nuclear armament within South Korea, posing a risk of triggering a regional nuclear domino effect[9].
Options Related to Scenario 2
Option 2-A (Deepening Cyber Sanctions and Law Enforcement Cooperation)This enhances the effectiveness of sanctions implementation by directly blocking North Korea's nuclear development funding channels. The institutionalized ROK-US-Japan trilateral cooperation framework facilitates securing momentum for implementation, and its relatively low diplomatic sensitivity makes it easy to pursue in conjunction with other options. However, there are technical limitations, as North Korea's cyber capabilities are continuously advancing [6][11], and the anonymity and decentralization of the cryptocurrency market make tracing difficult. Furthermore, the rapid advancement of AI technology is increasing the sophistication of cyber attacks [6][11], creating an asymmetric vulnerability where the defense side cannot keep pace with the attack side.
Option 2-B (Strengthening Extended Deterrence and Enhancing NCG Operations)This option effectively strengthens deterrence against North Korea's nuclear threats and alleviates South Korea's security anxieties. Sharing nuclear plans through the NCG also serves to deter South Korea's demand for independent nuclear armament. However, North Korea defines the NCG itself as a "nuclear war organization" [9] and uses it as justification for strengthening its own nuclear capabilities, creating a dilemma where enhanced deterrence could instead trigger a vicious cycle of escalating tensions. North Korea's strong backlash [5][2] against South Korea's pursuit of nuclear-powered submarines also exemplifies the side effects of this option.
Option 2-C (Strengthening Multilateral Sanctions Enforcement)This option can be expected to have a long-term pressure effect by systematically blocking North Korea's foreign currency revenue sources. However, given that China and Russia are exercising veto power on additional sanctions resolutions in the UN Security Council, the effectiveness of multilateral sanctions is structurally limited. In particular, the deepening military cooperation between North Korea and Russia [9] further weakens Russia's incentive to cooperate with the enforcement of sanctions against North Korea, exacerbating the conditions for implementing this option.
Options Related to Scenario 3
Option 3-A (Urgent Convening of the UN Security Council)This option has the symbolic effect of demonstrating international solidarity and securing the legitimacy of diplomatic pressure. However, given that China and Russia are almost certain to exercise their veto power, it has the fundamental limitation of being difficult to lead to actual additional sanctions resolutions. On the contrary, repeated vetoes could have the adverse effect of undermining the authority of the UN Security Council and the credibility of the sanctions regime against North Korea.
Option 3-B (Expanding Unilateral Sanctions and Strengthening Secondary Boycotts)As a realistic alternative to compensate for the limitations of UN sanctions, this option can be expected to have a tangible pressure effect by directly targeting Chinese companies' sanctions violations. However, this could lead to the side effect of intensifying US-China trade disputes, and there may be political constraints on increasing the intensity of secondary boycotts while the Trump administration is simultaneously pursuing trade negotiations with China.
Option 3-C (Strengthening ROK-US-Japan Military Cooperation and Constant Deployment of Strategic Assets)This is the most direct and visible means of deterring further provocations by North Korea. The deployment of strategic assets enhances the credibility of extended deterrence and alleviates security anxieties of allies. However, North Korea defines this as a "threat of nuclear war" and uses it to justify strengthening its own nuclear capabilities [2][9], making it crucial to maintain a balance between deterrence and provocation. There also exists a structural vulnerability where the US may face constraints in allocating strategic assets if other regional conflicts, such as a Taiwan crisis, occur simultaneously [9].
3. Feasibility and Risk Assessment
The feasibility of each option is determined by four variables: the diplomatic priorities of the Trump administration, North Korea's reaction, the level of coordination within the ROK-US alliance, and the positions of China and Russia.
In terms of short-term feasibility, Options 2-A (Intensifying Cyber Sanctions) and 2-B (Strengthening Extended Deterrence) are rated highest. Both options can be pursued within existing institutional frameworks, and a consensus base has already been formed among the ROK, US, and Japan. Cyber cooperation, in particular, has the advantage of being less susceptible to political variables due to its low diplomatic sensitivity and its nature as technical cooperation. Conversely, Option 1-C (Shifting to Arms Control Negotiations) is considered the least feasible, as it would be difficult to obtain the consent of South Korea and Japan and could potentially provoke bipartisan opposition within the US.
In terms of medium-term feasibility, Options 1-A (Comprehensive Negotiation Package) and 1-B (Phased Approach Prioritizing Nuclear Freeze) have the potential to materialize if President Trump's transactional diplomacy style aligns with the Lee Jae-myung administration's willingness to resume dialogue [15]. The conclusion of the Iran nuclear deal could also act as a catalyst for resuming North Korean nuclear diplomacy, further enhancing the feasibility of these options. However, given that North Korea has enshrined its status as a nuclear-weapon state in its constitution and defines denuclearization demands as "internal interference" [1][7], there is a practical constraint in providing incentives for them to come to the negotiating table.
In terms of risk assessment, Option 3-C (Constant Deployment of Strategic Assets) carries the highest risk. While this option can exert a deterrent effect in the short term, there is a risk of unintended military conflict if North Korea misinterprets it as a preemptive threat or uses it as a pretext to intentionally escalate tensions. The possibility of conflict due to miscalculation cannot be ignored, especially as North Korea showcases its capability to strike South Korean power facilities with tactical nuclear missiles [10] and declares the establishment of a nuclear-armed navy [14][17]. Conversely, Option 2-A (Intensifying Cyber Sanctions) carries relatively low risk, but it is not entirely risk-free as it could provoke North Korea's cyber retaliation.
4. Summary of Priority Response Measures by Scenario
The priority response measures for each scenario are summarized as follows.
If Scenario 1 (Resumption of North Korea-US Diplomacy) Materializes, the priority response measure is a phased approach that sets Option 1-B (Phased Approach Prioritizing Nuclear Freeze) as the short-term goal and develops it into Option 1-A (Comprehensive Negotiation Package). This strategy involves building a foundation of trust for negotiations through a nuclear freeze agreement, thereby deterring further provocations, and then expanding it into a comprehensive package linking phased denuclearization with corresponding measures. Close prior coordination among the ROK, US, and Japan is essential in this process, and special attention must be paid to alliance management to ensure that South Korea and Japan are not sidelined during negotiations. Option 1-C (Shifting to Arms Control Negotiations) should only be considered as a last resort, as it could be interpreted as officially abandoning the goal of denuclearization, and is currently inappropriate for prioritization.
If Scenario 2 (Maintaining the Status Quo While Strengthening Sanctions and Pressure) Continues, the priority response measure is a two-track approach that simultaneously pursues Option 2-A (Intensifying Cyber Sanctions) and Option 2-B (Strengthening Extended Deterrence). Cyber cooperation should be developed to further deepen the institutionalization of trilateral cooperation among the ROK, US, and Japan as an effective means of directly blocking North Korea's nuclear development funding. Strengthening extended deterrence should involve enhancing the substance of NCG operations and bolstering South Korea's conventional deterrence capabilities in a coordinated manner, ensuring it does not provide unnecessary pretexts for provocation by North Korea. Given the reality that cooperation from China and Russia is difficult to expect, Option 2-C (Strengthening Multilateral Sanctions Enforcement) should be realistically utilized as a complementary measure in conjunction with unilateral sanctions and secondary boycotts.
If Scenario 3 (Accelerated Advancement of North Korea's Nuclear Capabilities and Escalating Tensions) Materializes, the priority response measures involve immediately utilizing Option 3-B (Expanding Unilateral Sanctions and Strengthening Secondary Boycotts) while simultaneously pursuing Option 3-C (Strengthening ROK-US-Japan Military Cooperation) as a means of enhancing deterrence. However, Option 3-C requires meticulous management to maximize deterrence effects by coordinating the scale and frequency of strategic asset deployments while minimizing the risk of conflict due to miscalculation. Although Option 3-A (Urgent Convening of the UN Security Council) has limited effectiveness, it is advisable to pursue it in parallel as a symbolic measure to demonstrate international solidarity and secure the legitimacy of diplomatic pressure.
Common priority response measures that cut across the three scenarios include the institutional deepening of ROK-US-Japan cyber cooperation, maintaining the credibility of extended deterrence, and keeping diplomatic channels open. Regardless of which scenario materializes, maintaining these three foundations is a key condition for preserving the strategic flexibility of the United States and South Korea. In particular, as North Korea accelerates its strategy of normalizing its status as a nuclear-weapon state [1][5][7], a balanced approach is required that acknowledges the difficulty of a fundamental solution through sanctions and enhanced deterrence alone, while still maintaining diplomatic leverage.
5. Final Recommended Response Measures
Extension of US State of National Emergency on North Korea and Strengthening of ROK-US-Japan Cyber Cooperation: Comprehensive Recommended Response Measures and Implementation Plan
1. Comprehensive Assessment and Recommended Response Measures
The current security environment on the Korean Peninsula is characterized by a complex tension where North Korea's advancing nuclear capabilities, the US's maintenance of sanctions, and the strengthening of ROK-US-Japan cooperation are occurring simultaneously, while also presenting opportunities for diplomatic transition. The extension of the US state of national emergency on North Korea is interpreted as a dual signal that maintains the legal and administrative basis of the sanctions regime while not completely shutting off diplomatic flexibility, and the Trump administration's diplomatic confidence, following the conclusion of the Iran nuclear deal, could potentially extend to the North Korean nuclear issue [15]. Concurrently, Kim Jong Un's constitutional enshrinement of nuclear-weapon state status, public declaration of "nuclear forces that will overwhelm the world," and even the announcement of establishing a nuclear-armed navy [5][14] necessitate a realistic recognition that negotiations based on the premise of complete denuclearization in the traditional sense are unlikely to yield results in the short term.
The comprehensive assessment of this complex situation is summarized as follows: First, while the possibility of resuming North Korea-US summit talks is real, the likelihood of it leading to denuclearization is low; it is more probable that it will result in an interim agreement in the form of a nuclear freeze or arms control. Second, cybersecurity has already been structured as a key front for the implementation of sanctions against North Korea, and the institutionalization of trilateral cooperation among the ROK, US, and Japan is a strategic asset that should be sustained and deepened regardless of short-term outcomes. Third, the subtle difference in temperature between the South Korean new administration's willingness to resume dialogue and the US's stance of maintaining sanctions acts as a key variable to be managed in the ROK-US alliance's approach to North Korea.
Synthesizing the above assessments, this report proposesa dual-track strategy centered on 'maintaining deterrence and sanctions while pursuing phased diplomacy'"as the top priority response measure. This strategy involves maintaining pressure through sanctions and deterrence while simultaneously building a prepared negotiation architecture that can be utilized if the diplomatic window of resuming North Korea-US summit talks opens. Specifically, the implementation plan is structured around four pillars: deepening the institutionalization of cyber cooperation, strengthening the credibility of extended deterrence, preparing a phased incentive package based on a nuclear freeze, and multi-layered expansion of ROK-US-Japan mini-lateral cooperation.
2. Short-, Medium-, and Long-Term Implementation Plans
Short-Term Implementation Plan (0-6 months)
In the short term, the most urgent tasks are the substantial strengthening of the cyber cooperation framework and the preparatory work for a negotiation architecture in anticipation of the resumption of North Korea-US diplomacy. These two tasks are complementary, and neglecting either could undermine the coherence of the overall strategy.
In terms of cyber cooperation, the key is to translate the outcomes of the 5th ROK-US-Japan Trilateral Working Group Meeting on North Korean Cyber Threats into concrete action plans. Efforts should be accelerated to designate additional sanctions against North Korea-linked hacking groups, strengthen regulations on cryptocurrency exchanges, and deepen cooperation on fund tracing technologies. In particular, considering the trend of the Five Eyes alliance emphasizing joint responses to AI-based cyber threats [6][11], integrating AI-based threat detection and response capabilities into the ROK-US-Japan cyber cooperation framework should be set as a short-term task. To this end, it is necessary to institutionalize a real-time cyber threat information sharing channel among the three countries and increase the frequency and intensity of joint response exercises.
In terms of diplomatic preparation, it is crucial to pre-coordinate negotiation positions in anticipation of the Trump administration resuming North Korea-US contacts. Given that the Lee Jae-myung administration has directly requested President Trump for a diplomatic resolution of the North Korean nuclear issue [15], there is a risk of revealing cracks within the alliance if prior agreement is not reached between South Korea and the US on the red lines for negotiation and the scope of permissible incentives. Therefore, the scope of incentives that can be offered in exchange for a nuclear freeze, the possibility of adjusting joint exercises, and the conditions for sanctions relief should be pre-coordinated through closed-door working-level consultations between ROK and US diplomatic and security authorities. Additionally, care must be taken in message management to ensure that additional sanctions measures, such as the US's strengthening of restrictions on medical device exports [4], are not misinterpreted as diplomatic signals.
In terms of deterrence, based on the outcomes of the 6th meeting of the ROK-US Nuclear Consultative Group (NCG), measures to tangibly enhance the credibility of extended deterrence are necessary [9]. The fact that North Korea is vehemently condemning the NCG as a "nuclear war organization" paradoxically demonstrates that the NCG is effectively exerting deterrence against North Korea. The credibility of deterrence must be managed in a way that maintains the regularity and visibility of strategic asset deployments while avoiding unnecessary escalation of tensions.
Medium-Term Implementation Plan (6 months - 2 years)
In the medium term, although two paths diverge depending on whether North Korea-US diplomacy resumes, there are common tasks that must be pursued in either path.
On the path where North Korea-US diplomacy resumes, a phased negotiation strategy prioritizing a nuclear freeze must be implemented. Insisting on complete denuclearization as a prerequisite for negotiations is likely to prevent negotiations from taking place at all; therefore, a realistic approach would be to set a nuclear freeze agreement, including a halt to further nuclear tests and ICBM test launches, as the first-stage goal, and to provide incentives such as expanded humanitarian aid, opening liaison offices, and partial sanctions relief in stages in return. During this process, South Korea's pursuit of nuclear-powered submarines could become an obstacle to negotiations [5], necessitating prior coordination between South Korea and the US on whether this issue will be linked to the negotiations. Given that North Korea is employing a strategy of linking the NCG and South Korea's submarine pursuit under the unified frame of "ROK-US nuclear threat" to justify its status as a nuclear-weapon state [5], a diplomatic narrative strategy to dismantle this frame during negotiations must also be pursued.
On the path where North Korea-US diplomacy does not resume, the multi-layered expansion of ROK-US-Japan mini-lateral cooperation becomes the key task. Beyond cyber cooperation, it is necessary to institutionalize trilateral cooperation in various areas such as supply chain security, financial sanctions enforcement, and maritime interdiction, and further expand the cooperation network with partners like Australia and the United Kingdom [11]. In particular, given that North Korea is deepening military cooperation with Russia and has reportedly dispatched approximately 15,000 troops to the Ukrainian front [9], diplomatic efforts to strengthen international solidarity for the enforcement of sanctions against North Korea must be pursued in parallel. Conventional deterrence enhancement measures, such as South Korea's drone force expansion plan [8], should also be accelerated during this period and efficiently pursued in conjunction with US technical support.
In terms of cyber cooperation, in the medium term, the ROK-US-Japan Trilateral Working Group on North Korean Cyber Threats should be institutionalized as a standing body, and its institutionalization should be deepened by expanding its authority and functions. Moving beyond the current working group format, the establishment of a joint cyber threat response center among the three countries should be considered, and a cooperation system with private financial institutions and cryptocurrency exchanges should be established to increase the efficiency of blocking North Korea's cybercrime proceeds. Given the rapidly increasing threat of AI-based cyber attacks [6][11], the joint development of AI-based threat detection and response capabilities should also be included as a medium-term task.
Long-Term Implementation Plan (Over 2 years)
In the long term, while maintaining the ultimate goal of denuclearization on the Korean Peninsula, strategic flexibility must be secured to prepare for the possibility that the path may shift from traditional denuclearization negotiations to nuclear arms control or phased nuclear reduction negotiations. Given that Kim Jong Un has constitutionally enshrined his status as a nuclear-weapon state and even declared the establishment of a nuclear-armed navy [14][17], setting complete denuclearization as a short- to medium-term goal carries the risk of deepening the gap with reality. Therefore, in the long term, the possibility of shifting the framework to nuclear arms control negotiations should be prepared as a strategic option, but it must be managed cautiously to avoid undermining the shared ROK-US goal of denuclearization by publicly announcing it.
The long-term institutionalization of ROK-US-Japan mini-lateral cooperation is also a key task. Efforts should be made to elevate trilateral security cooperation into a comprehensive security partnership, moving beyond the current focus on cyber cooperation. This implies developing a structural cooperation system that jointly responds to a wide range of security challenges, including China's regional hegemony challenges and Russia's expanding regional influence, not limited to the North Korean issue [9]. In particular, as North Korea supports China's "One China" principle and deepens military cooperation with Russia [9], the strategic value of ROK-US-Japan cooperation is expanding beyond the North Korean nuclear issue to encompass overall Indo-Pacific security.
3. Monitoring Indicators and Trigger Points
To continuously assess the effectiveness of the recommended response measures and adjust the strategy, it is essential to pre-establish clear monitoring indicators and trigger points.
Diplomatic Trends IndicatorsThe most critical monitoring target is the occurrence of direct contact or the activation of back channels between North Korea and the US. If President Trump changes the tone of his public remarks towards North Korea, or if North Korea sends signals indicating a willingness to engage in dialogue, these should be immediately detected to activate preparedness for negotiations. Attempts by the Lee Jae-myung administration to engage with North Korea and the US response are also important indicators; if the temperature difference in the approach to North Korea between South Korea and the US widens, urgent consultations are needed for alliance management [15].
Nuclear and Missile Capability IndicatorsIn relation to these indicators, further nuclear tests or ICBM test launches by North Korea should be set as the strongest trigger points for closing the diplomatic window. In such cases, a response plan should be prepared in advance to immediately implement enhanced sanctions and visible extended deterrence measures. Conversely, if North Korea maintains a period of restraint in nuclear and missile tests, this can be interpreted as a diplomatic signal and used as a trigger to explore contact channels. The progress of Kim Jong Un's nuclear-armed navy construction [14][17] and the advancement of tactical nuclear missile capabilities [10] are also key indicators that need to be continuously tracked.
Cyber Threat IndicatorsIn relation to this, the scale and methods of cryptocurrency theft by North Korea-linked hacking organizations, and the frequency and sophistication of attempts to infiltrate financial institutions are key monitoring targets. In particular, the adoption of AI-based cyber attack techniques serves as a crucial trigger point for determining the necessity of upgrading the response capabilities of the ROK-US-Japan cyber cooperation framework[6][11]. The effectiveness of the cooperation framework must also be regularly assessed by examining the achievements in sanctions designation and law enforcement cooperation by the ROK-US-Japan Trilateral Cyber Threat Diplomacy Working Group.
Regional Security Environment IndicatorsIn relation to this, the deepening of Russia-North Korea military cooperation and changes in North Korea-China relations are important monitoring targets. If North Korea provides additional troops or weapons to Russia[9], or if signs emerge of China deviating from the implementation of sanctions against North Korea, these would become trigger points necessitating a fundamental re-evaluation of the effectiveness of the pressure strategy on North Korea. The progress of South Korea's pursuit of acquiring nuclear-powered submarines must also be monitored in conjunction with North Korea's reactions, and advance preparations are needed for the possibility that this could become an obstacle to the resumption of North Korea-US diplomacy[5].
4. Summary Conclusion
The extension of the US state of national emergency regarding North Korea and the strengthening of ROK-US-Japan cyber cooperation are, on the surface, extensions of the existing pressure policy toward North Korea. However, beneath the surface, two conflicting dynamics are simultaneously at play: the diplomatic momentum emerging after the Iran nuclear deal and North Korea's advancement of its nuclear capabilities. In a situation where Kim Jong Un is normalizing the status of a nuclear-armed state and even declaring the creation of a nuclear-armed navy[14][17], the traditional negotiation paradigm based on complete denuclearization faces practical limitations. However, the diplomatic confidence of the Trump administration and the willingness of the Lee Jae-myung administration to resume dialogue[15] leave open the possibility of new forms of diplomatic approaches.
In this complex situation, the optimal response strategy is a dual-track approach that maintains the pressure policy through sanctions and deterrence while simultaneously preparing a phased diplomatic architecture with nuclear freeze as a first-stage objective. The institutional deepening of cyber cooperation is a strategic asset that should be sustained under any scenario, and the multi-layered expansion of ROK-US-Japan trilateral cooperation should be established as a structural investment contributing to overall regional security in the Indo-Pacific, beyond the North Korean nuclear issue. In the short term, focus should be placed on strengthening cyber cooperation and pre-coordinating negotiation positions; in the medium term, a branching strategy should be implemented based on whether diplomatic engagement resumes; and in the long term, strategic flexibility, including the possibility of shifting to a framework of nuclear arms control, should be secured. This is the best path to manage this complex situation.
