The Establishment of U.S. Southern Command's 'Shield of the Americas' and the Realignment of the Western Hemisphere Sphere of Influence Emanating from Venezuela

Executive Summary

Through the operation to arrest President Maduro in January 2026 and the establishment of the Southern Command-led 'Shield of the Americas' joint task force, the United States is reaffirming its dominance over the Western Hemisphere, an implementation case of the policy line stipulated in the November 2025 National Security Strategy. Similar to the precedent of the late 19th century, when Britain acknowledged the U.S. sphere of influence in the Western Hemisphere in the wake of the Venezuela crisis and instead shifted its Asian burden onto the Anglo-Japanese Alliance, the United States is seeking to consolidate its own backyard in the Western Hemisphere in order to secure the capacity to concentrate resources on countering China in the Indo-Pacific. The Rodríguez interim government has abruptly pivoted to a pro-American line, but it carries political vulnerabilities, including internal fragmentation within the anti-imperialist left and the limited restoration of consular relations with Israel; the degree of institutionalization of the Southern Command framework and whether its actual operational capacity expands are expected to constitute a turning point for the future regional order. Korea needs a phased approach that separates the establishment of channels from actual investment decisions with respect to entry into Venezuela's crude oil and resource supply chains, while separately tracking the implications of this case for U.S. policy toward North Korea and for the Indo-Pacific alliance structure.

Issue Situation Analysis: The Establishment of U.S. Southern Command's 'Shield of the Americas' and Regional Realignment Emanating from Venezuela

1. Background and Developments

The trigger for the Venezuela crisis was the U.S. military's operation to arrest Maduro in January 2026. U.S. special forces infiltrated a safe house in Caracas and secured custody of President Maduro and his wife [2]. The time elapsed from the start to the conclusion of the operation was a mere approximately two hours and thirty minutes [2]. There was no prior consent from the Venezuelan government or authorization from an international organization [2]. This is exceptional in that it constitutes direct military intervention targeting a sitting sovereign state leader [2].

This operation was not a sudden decision. The U.S. military had sustained a show of force, including a maritime blockade, near Venezuela since September 2025 [8]. The CIA had stationed a small team on the ground for months beforehand, tracking Maduro's movement routes and security arrangements [2]. Combined satellite intelligence, signals intelligence, and drone reconnaissance assets enabled a three-dimensional grasp of even the safe house's location and guard deployment [2].

The policy basis for this intervention had already been laid out in the U.S. National Security Strategy (NSS) released in November 2025. The NSS explicitly stated the U.S. intent to reinforce its dominance over the Western Hemisphere [5]. EAI's analysis links this to the historical pattern in which "a maritime hegemon, when confronted with a maritime power transition by a challenger state, redeploys naval power across surrounding theaters while seeking new alliance relationships or readjusting existing ones" [5]. The precedent cited is that of Britain in the late 19th century, which accepted the U.S. claim to a Western Hemisphere sphere of influence in the wake of the 1895 Venezuela crisis, and instead adjusted its naval posture in Asia through the Anglo-Japanese Alliance [5]. Venezuela, which had requested U.S. intervention in the Western Hemisphere some 130 years ago, has thus once again become the stage for this drama [5].

2. Current Situation

Following Maduro's arrest, the Delcy Rodríguez interim government abruptly pivoted toward a pro-American line. The Kuwait Times reported that the anti-imperialist left camp is openly expressing its discontent with the close relationship between the interim government and Washington [16]. Local reporting assesses that, seven months after Maduro's arrest, the Venezuelan left-wing forces are fragmenting into multiple factions internally [16].

The most symbolic change is the restoration of consular relations with Israel. Venezuela and Israel resumed relations that had been severed since the 2009 Gaza offensive, after a 17-year gap [4][7][11][13][15]. The catalyst was the humanitarian aid mission dispatched by Israel following the major earthquake that occurred in June [4][11]. Haaretz, while drawing a line that this agreement does not amount to a full restoration of diplomatic relations, emphasized that an official coordination channel between Jerusalem and Caracas has been established [13]. Al Jazeera characterizes this as part of a "major realignment" being pursued by the Rodríguez interim government [7].

Militarily, Southern Command, together with 18 Latin American and Caribbean allied nations, has established the 'Shield of the Americas' (Escudo de las Américas) joint task force. The commander is Marine Corps Major General Kevin Zarate [1]. El Nacional reported that this joint force was announced in a manner that spotlighted the Venezuela operation [1]. The Trinidad and Tobago Express reported that the Western Hemisphere Joint Task Force (JTF-WHEM) activated by Southern Command and the 18-nation 'Americas Cartel Countering Coalition (A3C)' are being combined under the banner of countering transnational criminal organizations [14]. Washington described Trinidad and Tobago's continued participation as reflecting a "shared security commitment" [14].

On the energy front, Columbia University's CGEP points out that while Venezuela's new oil regulations provide investment incentives, political uncertainty and the burden of earthquake recovery could hinder investment [6]. Amid the disruption of an estimated 10-15 million barrels per day of crude oil supply caused by the blockade of the Strait of Hormuz, the potential of Venezuelan crude as an alternative supply source is being reexamined [6][9].

3. Key Actors and Positions

U.S. Southern Command (SOUTHCOM)seeks to institutionalize a military cooperation system across the Western Hemisphere through the 'Shield of the Americas.' The fact that the Venezuela operation was highlighted at the time of the announcement suggests that this joint force's substantive goal lies in managing the Western Hemisphere sphere of influence, beyond the stated rationale of countering cartels [1].

Delcy Rodríguez Interim Governmenthas chosen a pro-American line for the sake of survival, severing ties with the legacy of the Maduro regime. The restoration of relations with Israel is a signal of its intent to break away from the past Iran-centered alliance structure [4][7]. However, this policy shift is accompanied by backlash within the interim government itself, particularly from part of the ruling party and left-wing forces, meaning its political foundation has not been fully consolidated [16].

The Government of Israelhas converted the point of contact formed through humanitarian aid following the June earthquake into a diplomatic achievement. For the Netanyahu government, restoring relations with Venezuela—which had been a symbolic bastion of anti-Israel sentiment in Latin America—contributes to easing regional isolation [15].

Caribbean Coastal States including Trinidad and Tobagoare deepening security cooperation with the United States within the JTF-WHEM and A3C frameworks. The U.S. Embassy has characterized this as a "shared commitment to disrupting transnational criminal organization networks," openly praising the cooperation of participating countries [14].

Venezuela's Anti-Imperialist Leftconstitutes the faction opposing the interim government's close ties with Washington and is becoming the axis of internal division within the ruling party [16]. The existence of this faction demonstrates that the Rodríguez government's pro-American pivot has not achieved full domestic legitimacy.

4. Key Issues

First, the key question is how the Maduro arrest operation is linked to the NSS's intent to reinforce dominance over the Western Hemisphere. The NSS had already codified Western Hemisphere primacy as of November 2025 [5]. The establishment of the 'Shield of the Americas' is read as the stage at which this documented policy intent is being concretized into an actual multilateral military institution [1][5].

Second, it remains uncertain in which direction the 18-nation joint force will be institutionalized, given the gap between the stated rationale of countering cartels and the actual emphasis on the Venezuela operation. As in the case of Trinidad and Tobago, individual member states participate under the banner of countering transnational crime, yet Southern Command's announcement placed Venezuela at the forefront [1][14].

Third, whether the Rodríguez interim government's pro-American pivot is domestically politically sustainable is a matter to be observed. Should the fragmentation of left-wing forces intensify, the interim government's abrupt shift in foreign policy could face backlash [16].

Fourth, there is the possibility of a realignment of raw material and energy supply chains. Amid the clash between new oil regulations and investment incentives on one hand, and the burden of earthquake recovery and political uncertainty on the other, the market's concern is whether Venezuelan crude oil can establish itself as an alternative supply source amid Strait of Hormuz risk [6][9].

II. In-Depth Issue Analysis

In-Depth Issue Analysis: The Fundamental Causes and Structural Context of the 'Shield of the Americas' Establishment

1. Fundamental Cause: Maritime Power Transition and the Project to Reclaim the Western Hemisphere

Reading the establishment of 'Shield of the Americas' as a mere expansion of counter-insurgency operations misses the essence. This joint force's roots lie in the November 2025 National Security Strategy (NSS). The NSS pinned down, as policy doctrine, the intent to reinforce dominance over the Western Hemisphere [5]. The Maduro arrest is an implementation case that came just two months after this document's release [5].

EAI's analysis defines this as a pattern of a maritime hegemon responding to power transition. A maritime hegemon, when confronted with a challenger's naval buildup, redeploys naval power across surrounding theaters [5]. At the same time, it either newly builds alliance relationships to substitute for this, or readjusts existing ones [5]. Britain's case in the late 19th century illustrates this pattern. As the naval buildups of the United States, Germany, and Japan occurred simultaneously, Britain, taking the 1895 Venezuela crisis as an opportunity, accepted the U.S. claim to a Western Hemisphere sphere of influence [5]. Instead, it concluded the First Anglo-Japanese Alliance in 1902, transferring the naval burden in Asia [5]. It also entered into the Entente Cordiale with France in 1904, concentrating on the defense of the European mainland [5].

Today's United States faces the challenge of China's rising maritime power. Within this configuration, the Western Hemisphere is the first testing ground for a redeployment strategy in which Washington reaffirms dominance over its own backyard and channels the resulting capacity into the Indo-Pacific. It is no coincidence that Venezuela, which requested U.S. intervention some 130 years ago, has once again been summoned as the stage for this [5].

2. Structural Context: The Triple Structure of Politics, Economics, and Security

Politically, the Maduro arrest symbolizes a shift in the U.S. stance toward the norm-based international order. Instances of securing custody of a sitting sovereign state leader without prior consent or authorization from an international organization are rare in precedent [2]. This runs directly counter to the principle of sovereign respect that the United States has espoused since the end of the Cold War. The Rodríguez interim government's rapid pivot toward the United States emerged from the process of filling this political vacuum. Internally, however, backlash from the anti-imperialist left camp has been accumulating [16]. The signs of the ruling party fragmenting into multiple factions seven months after Maduro's arrest [16] demonstrate that the interim government's pro-American line is proceeding without a domestic political foundation.

Economically, a realignment of energy supply chains is at stake. Columbia University's CGEP analysis points out that while Venezuela's new oil regulations provide investment incentives, political uncertainty and the burden of earthquake recovery offset this [6]. The possibility has thus opened for Venezuelan crude oil, long blockaded under the Maduro regime, to re-enter the market under a U.S.-friendly government. This is linked, amid the repeated blockage of 10-15 million barrels per day of supply due to the Strait of Hormuz blockade [6][9], to the U.S. motivation to secure an alternative supply source in order to reduce dependence on the Middle East.

In the security structure, Southern Command's multilateral configuration stands out. The 'Shield of the Americas' encompasses 18 Latin American and Caribbean allied nations [1]. Trinidad and Tobago has deepened cooperation under the banner of countering transnational criminal organizations through the activation of the Western Hemisphere Joint Task Force (JTF-WHEM) and its participation in the 18-nation Americas Cartel Countering Coalition (A3C) [14]. While ostensibly espousing pure counter-terrorism and counter-cartel coordination, this in substance has the effect of permanently institutionalizing a Southern Command-centered multilateral command structure within the region.

3. Comparison with Historical Precedents

The most direct precedent is the 1895 Venezuela crisis. At that time, Britain accepted U.S. Monroe Doctrine-based intervention in the border dispute between Venezuela and British Guiana [5]. This is a case in which a maritime hegemon ceded a particular sphere of influence to an emerging challenger while securing strategic capacity in other theaters [5]. Today's configuration is precisely the opposite. The United States itself, as the hegemon, is directly reclaiming the Western Hemisphere and seeking to channel the resulting capacity into the Indo-Pacific.

The Saudi Arabia-Türkiye-Pakistan Mecca Joint Defense Pact currently underway in the Middle East also offers a point of comparison. This pact originated from the Gulf states' reassessment of trust in U.S. security commitments [10]. As the U.S. share of crude oil imports from the Gulf declined from 25% in 2014 to 8% in 2025, Washington's incentive to intervene structurally weakened, prompting regional states to seek independent means of deterrence [10]. The Western Hemisphere and the Gulf region are moving in opposite directions. Whereas the Gulf is seeking regional self-reliance in response to the weakening of U.S. intervention incentives, the Western Hemisphere shows a pattern in which the United States is intensifying direct intervention and reaffirming its sphere of influence. This asymmetry supports the assessment that the United States is differentially allocating resources and attention across regions.

4. Key Variables

The first variable is the domestic political sustainability of the Rodríguez interim government. Should fragmentation within the left camp shake the interim government's governing foundation, the rapid pivot toward a pro-American line could face a backlash [16]. The second variable is the depth of the Israel-Venezuela relationship. Haaretz explicitly stated that this agreement does not amount to a full restoration of diplomatic relations [13]. Whether it develops beyond the consular level into the reopening of embassies will serve as an indicator of whether the past Iran-centered alliance configuration has been dismantled. The third variable is the actual level of military integration among the 18 nations under the 'Shield of the Americas.' Just as the Mecca Pact falls short of a NATO-style automatic intervention clause and functions instead as a symbolic signal [10], the Shield of the Americas too may exhibit a gap between nominal multilateral configuration and actual command and resource allocation. The fourth variable is the pace of Venezuelan crude oil's return to the market. How much the investment incentives of the new oil regulations offset earthquake recovery costs and political uncertainty [6] will determine the actual timeline for the realignment of raw material and energy supply chains.
