Rising Military Tensions Between Israel and Turkey in Syria: A Geopolitical Risk Analysis

Executive Summary

In the security vacuum following the collapse of the Assad regime, Israel and Turkey are engaged in a structural competition to establish their respective spheres of influence. Israel's August 18 airstrike on the Abu al-Duhur airbase occurred just after a visit by a Turkish military delegation. In response, Turkey has adopted a dual strategy of issuing harsh rhetoric while refraining from direct military retaliation. This approach is linked to its institutional constraints as a NATO member, and the current pattern of harsh rhetoric and sporadic airstrikes is highly likely to continue. The United States is calling for restraint from both sides, but its ability to mediate is limited by exposed policy differences between the Trump and Netanyahu administrations. The South Korean government and businesses should avoid strategies that rely solely on Turkey as a patron state, designate the Idlib-Aleppo border region as a distinct risk zone, and continuously monitor their aviation and logistics exposure.

I. Situational Analysis

Rising Military Tensions Between Israel and Turkey in Syria: A Situational Analysis

1. Background and Developments

The security vacuum in Syria following the collapse of the Assad regime in December 2024 has become an arena for two regional powers, Israel and Turkey, to establish their respective spheres of influence. Since the fall of Assad, Israel has conducted hundreds of airstrikes across Syria. This stems from its policy of labeling the Islamist forces forming the new government as jihadists and maintaining a high state of alert [15]. Turkey, in contrast, has positioned itself as the key patron of the al-Sharaa transitional government, publicly stating its intention to support the rebuilding of the Syrian army and the restoration of its infrastructure [3].

The current incident was triggered by an Israeli airstrike on the Abu al-Duhur airbase in the early hours of August 18. The base, located in Idlib province, is 70 km from the Turkish border [17]. Israeli fighter jets struck the runway and hangar facilities eight times, with no reported casualties [13]. According to the Tehran Times, the airstrike occurred just hours after a Turkish military delegation had inspected the base [12]. This has led to interpretations that Israel preemptively neutralized the facility immediately after the Turkish side explored the possibility of its restoration.

2. Current Situation

On August 20, two days after the strike, the war of words between the two sides escalated into a series of official denials. Israeli Defense Minister Katz posted directly on X that Erdoğan was "dragging Turkey into a dangerous adventure" [1]. Israel claimed it conducted the preemptive strike after detecting signs that Turkish forces were about to be deployed to the base [1][3].

The Turkish Ministry of National Defence immediately denied that any of its troops were stationed at the base, while reaffirming its existing position of continuing to support the development of the Syrian military's capabilities [1]. The Turkish Presidency described Israel's claims as "unacceptable," countering that they were an attempt to justify Israel's "illegal" attack. However, it did not deny the possibility of future troop deployments [7]. Al-Monitor assessed this Turkish response as a "signal of restraint," noting that Ankara has taken no military retaliatory measures apart from its harsh rhetoric [14]. In an August 18 statement, the Turkish Foreign Ministry strongly criticized the Israeli airstrike for undermining Syria's territorial integrity and stability [5].

The U.S. position is a source of pressure for both sides. U.S. Special Envoy for Syria Tom Barrack publicly criticized the airstrike as an "unnecessary escalation of tensions" [15][16]. The U.S. ambassador to Turkey also separately condemned the bombing [11]. Based on these developments, The Times of India reported that the rift between the Trump and Netanyahu administrations is deepening, interpreting it as an exposure of the differing views between Washington and Tel Aviv on Syria policy [18].

3. Key Actors and Positions

Israeldefines Turkey's establishment of a military foothold in Syria as a security threat. Defense Minister Katz stated, "Israel will not allow any entity to threaten its security" [1]. Arab News analyzed the airstrike as a calculated warning message to the new government in Damascus and its patron, Turkey, going beyond merely striking Syrian infrastructure [9]. Sweden's Dagens Nyheter presented a similar view, suggesting the intent was to preemptively warn Turkey against securing an airbase in Syria [11].

Turkeyhas a clear interest in maintaining its status as the primary patron of the new Syrian government. Based on its alliance with the al-Sharaa regime, it has been involved in the project of rebuilding the Syrian army [3][17]. At the same time, it appears to be avoiding a direct military confrontation with Israel, refraining from actual military retaliation despite its defense ministry's statements [14].

Syrian Transitional Governmentdefined the airstrike as a violation of its sovereignty. Foreign Minister Asaad al-Shibani criticized it as an "unjustified provocation, a violation of Syrian sovereignty, and a direct threat to regional stability" [13]. However, the al-Sharaa government lacks the military capability to engage in a direct confrontation with Israel. The Tehran Times described this as "al-Jolani's appeasement policy," pointing out that the airstrikes continued despite the new Syrian government's conciliatory posture toward Israel [12].

United Stateshas taken on the role of mediator between its two allies, but its effectiveness is limited. Despite Special Envoy Barrack's public criticism, Israel continued its airstrikes [15][16]. An Indian media outlet pointed to this as evidence of accumulating fatigue in the Trump-Netanyahu relationship [18].

4. Key Issues

First, the factual basis regarding the deployment of Turkish forces to the Abu al-Duhur airbase remains unclear. Israel cited an imminent deployment as the reason for its strike, while Turkey has completely denied any presence there [1]. There has been no verifiable third-party confirmation.

Second, the competition for spheres of influence between Israel and Turkey, with Syria as the arena, is becoming structural. Both countries are key U.S. allies, yet they are clashing over influence on the new Syrian government [7]. As each tries to fill the security vacuum left by Assad's fall in its own way, there is a high probability of repeated friction.

Third, U.S. mediation capabilities are being tested. Despite critical remarks from Special Envoy Barrack, Israel's policy of conducting airstrikes has not changed [15]. A key point to watch is whether Washington possesses the means to effectively deter conflict between its two allies.

Fourth, the level of Turkey's response will determine whether the conflict escalates. A key variable determining the next level of tension is whether the "signal of restraint" noted by Al-Monitor will be maintained, or if harsh rhetoric will translate into actual military action [14].

II. In-Depth Analysis

Rising Military Tensions Between Israel and Turkey in Syria: An In-Depth Analysis

1. Analysis of Root Causes

The ostensible reason for the airstrike was to prevent the deployment of Turkish forces to the Abu al-Duhur airbase. However, at its root lies a fundamental conflict of interest between Israel and Turkey over spheres of influence in Syria.

Israel's Syria policy has followed a consistent principle since the fall of Assad: a deep distrust of the Islamist forces that formed the new government. Even after the al-Sharaa transitional government took control of Damascus, Israel has continued to carry out hundreds of airstrikes [15]. Israel's concern is not the regime itself, but military control over Syrian airspace and border areas. If Turkish forces were to secure an airbase in Idlib, it would mean the establishment of a NATO member's tangible military infrastructure near Israel's northern border. This represents a strategic change that Israel would find difficult to tolerate.

From Turkey's perspective, Syria operates under a different logic. The Erdoğan government, as the key patron of the al-Sharaa regime, has publicly supported the rebuilding of the Syrian army and the restoration of its infrastructure [3][1]. This is not merely humanitarian aid; it is intertwined with Turkey's dual objectives of containing Kurdish forces and securing a leading position in the Syrian reconstruction market. This is evidenced by the fact that while the Turkish Ministry of National Defence denied a current presence at the base, it did not rule out the possibility of future deployments [7]. The circumstances reported by the Tehran Times—that Israel struck the base just after a visit by a Turkish delegation [12]—support the assessment that Israel perceives Turkey's expanding military foothold in Syria as a tangible threat.

2. Structural Context

Security Structure: The Power Vacuum Created by Assad's Fall

The security vacuum in Syria has been a persistent structural variable since December 2024. Israel and Turkey are each filling the space left by the disappearance of the Assad regime, which had been a singular axis of deterrence. Israel is approaching the situation with military deterrence, while Turkey is using political and military patronage. These two approaches were not inherently incompatible. However, in regions adjacent to the Turkish border, such as Idlib, the two countries' spheres of influence inevitably overlap physically. The fact that the Abu al-Duhur airbase is located just 70 km from the Turkish border [17] symbolically illustrates this structural tension.

Political Structure: The Domestic Political Constraints of Both Leaders

The Netanyahu government has a history of using a hardline foreign policy as a political asset during its war with Iran and the stalemate in Gaza negotiations [6][8]. Defense Minister Katz's "dangerous adventure" remark is not unrelated to this context. The Erdoğan government has also used its Syria policy as a tool to rally its domestic support base. However, as Al-Monitor has pointed out, Turkey is pursuing a dual strategy of issuing harsh rhetoric while refraining from military retaliation [14]. This is linked to Turkey's institutional position as a NATO member. A direct military conflict with Israel could have repercussions at the NATO level.

The U.S. Factor: Washington's Dual Burden

The fact that both Special Envoy Tom Barrack and the U.S. ambassador to Turkey criticized Israel's airstrike [15][11] reveals America's structural dilemma. Washington considers both Israel and Turkey to be key allies. If the two allies clash in Syria, it is difficult for the United States to take a side. The report by The Times of India on a supposed rift between Trump and Netanyahu [18] can be seen as an instance of this structural burden coming to the surface. U.S. policy in Syria is designed on the premise of the al-Sharaa government's stability. Israel's repeated airstrikes are a variable that undermines this very premise.

3. Historical Precedents and Comparison with Similar Cases

The relationship between Israel and Turkey originally began as a tacit security partnership during the Cold War. The turning point for a serious deterioration in relations was the 2010 Mavi Marmara incident. Since then, through successive Gaza wars, the Erdoğan government's rhetoric against Israel has grown increasingly harsh. The current situation is an extension of this long-standing conflict. What is different from the past, however, is that the two countries are now experiencing a direct military conflict of interest in a third territory, Syria. While past conflicts were primarily diplomatic wars of words centered on the Gaza and Palestinian issues, the current phase is different in nature, involving a physical standoff over actual airstrikes and military deployments.

Another relevant case is Israel's pattern of containing Hezbollah and Iran during the Syrian civil war. Israel has maintained a policy of conducting preemptive strikes within Syrian territory, including the elimination of senior Iranian Revolutionary Guard Corps officials [8]. The recent airstrike on Abu al-Duhur can be seen as an extension of this same logic: the principle of physically eliminating a threat before it materializes. However, the nature of the escalation risk is different this time, as the target is not a non-state actor but a NATO member state.

The case of the Mecca Defense Pact also offers a point of comparison. According to an EAI analysis, the joint defense agreement between Saudi Arabia, Turkey, and Pakistan is "most likely to function as a symbolic deterrent signal for the time being, given that the official text has not been released and the political-military coordination body is in its early stages" [4]. Turkey's response in Syria shows a similar pattern: it is limited to sending deterrent signals through harsh rhetoric and does not lead to actual military retaliation. This suggests that Turkey is striking a careful balance between its dual alliance structure within NATO and its tangible interests in Syria [4].

4. Key Variables Shaping Future Developments

The Actual Deployment of Turkish ForcesThis is the first variable. Although the Turkish Ministry of National Defence currently denies any deployment [1], if Turkey were to actually deploy military assets in areas near Israel, such as Idlib, the level of Israel's response would likely be qualitatively different. Conversely, if Turkey refrains from a tangible deployment for the time being and adjusts its level of involvement to focus on infrastructure support, the current war of words may subside over time.

The Effectiveness of U.S. MediationThis is also a key factor. The fact that both Special Envoy Barrack and the U.S. ambassador criticized Israel [15][11] can be read as a signal that Washington will not ignore the issue. However, with the policy differences between the Trump and Netanyahu administrations already exposed [18], it is uncertain whether U.S. pressure can actually control Israel's policy of conducting airstrikes.

The Position of the al-Sharaa GovernmentThis is another variable. The Syrian transitional government is in a position where it must balance between Israel and Turkey. Although the Syrian foreign minister protested the Israeli airstrike as a "violation of sovereignty" [13], the underlying structure of its dependence on Turkish military support remains unchanged. If the al-Sharaa government, in the face of repeated Israeli airstrikes, leans toward expanding military cooperation with Turkey, the frequency of Israeli preemptive strikes could actually increase.

The Possibility of NATO-Level InvolvementThis is the most important variable in the long term. So far, the incident has remained at the level of a bilateral war of words between Israel and Turkey. However, if Turkey requests alliance-level discussions based on its status as a NATO member, the nature of the issue could expand from a regional conflict to an issue of alliance politics. In that case, a new dynamic of pressure on Israel from within the Western bloc could emerge.
