The initial agreement between the United States and the Islamic Republic of Iran to end the recent war marks more than a temporary ceasefire. It represents a possible reorganization of the regional balance of power. Although the agreement is framed as a diplomatic mechanism to halt hostilities, reopen the Strait of Hormuz, address Iran’s nuclear program, and create a 60-day window for further negotiations, its deeper significance lies in the way it alters regional threat perceptions. Nowhere is this shift more consequential than in Turkey. For Ankara, the agreement is not only about Iran’s nuclear program or sanctions relief; it is about Israel’s expanding military posture, the future of Lebanon, the role of Hezbollah, and Turkey’s own place in the emerging Middle Eastern order.
Turkey has long viewed Hezbollah with deep suspicion. From the Turkish state’s traditional security perspective, Hezbollah was an Iranian-backed Shi‘i militia, a destabilizing non-state actor, and a proxy instrument of Tehran’s regional strategy. Turkish Islamists were never naturally sympathetic to Hezbollah either, despite shared anti-Israeli rhetoric, because the Turkish Islamist imagination was historically rooted in Sunni political networks, the Muslim Brotherhood tradition, and Ottoman-Sunni memory. Hezbollah, by contrast, belonged to the Shi‘i revolutionary universe of Iran. For many years, therefore, Turkey’s view of Hezbollah was shaped by sectarian distance, geopolitical rivalry with Iran, and the fear that armed non-state actors could undermine state sovereignty.
Yet this perception has changed significantly. Israel’s recent military behavior and anti-Turkish rhetoric have transformed how Ankara interprets Hezbollah’s regional function. Turkish officials and pro-government circles increasingly see Israel not merely as a state defending itself against threats but as an expansionist power seeking to reorder the region through military force. Israel’s operations in Gaza, Lebanon, Syria, and Iran have reinforced the perception that Israel is no longer satisfied with deterrence or limited security operations. Rather, it appears to be pursuing a new strategic doctrine based on preemptive war, territorial buffers, military domination, and the weakening of all forces that could resist Israeli power.
This is where Hezbollah enters Turkey’s new strategic imagination. Ankara may not admire Hezbollah ideologically. It may not trust Iran. It may still worry about Shi‘i militias and Iranian influence. But in the current climate, Hezbollah is increasingly seen as a first line of defense against Israel’s expansion. In Turkish strategic thinking, Hezbollah’s survival prevents Israel from acting with a completely free hand in Lebanon and Syria. If Hezbollah is destroyed, Israel’s military reach could extend more confidently toward Syria, Iraq, and even the eastern Mediterranean. From Ankara’s perspective, this would not simply weaken Iran; it would also weaken Turkey’s strategic depth.
The U.S.–Iran agreement reinforces this logic because Lebanon is reportedly included in the de-escalation framework. Iran has successfully linked the Iranian and Lebanese fronts, insisting that a final agreement must restrain Israeli operations against Hezbollah and respect Lebanon’s sovereignty and territorial integrity. This is one of the most consequential aspects of the agreement. Tehran has forced Washington to recognize, at least indirectly, that the Lebanese front cannot be separated from the Iranian front. For Israel, this is alarming because it limits its freedom of action. For Turkey, however, this linkage may appear useful. It constrains Israel, preserves Hezbollah as a deterrent force, and prevents the total collapse of the Iran-led resistance axis.
Turkey’s position is not identical to Iran’s. Ankara does not want Iranian hegemony in the region. It has competed with Iran in Syria, Iraq, the Caucasus, and the broader Islamic world. Yet Turkey’s fear of unchecked Israeli power is now becoming more urgent than its fear of Iranian influence. This is the major transformation. In the past, Turkey saw Iran and Hezbollah as destabilizing actors. Today, it increasingly sees Israel as the more aggressive and unpredictable power. This does not mean that Ankara has become pro-Iranian. It means that Turkish threat perception has shifted from sectarian rivalry to geopolitical balancing.
The change is also driven by Israel’s anti-Turkish rhetoric. Israeli officials and commentators have increasingly portrayed Turkey under Erdoğan as a hostile Islamist power, a supporter of Hamas, and a possible future adversary. Such rhetoric has had a powerful effect in Ankara. It confirms the belief that Israel views Turkey not as a difficult partner but as a strategic enemy. Once Turkey concludes that Israel sees it as part of the hostile regional camp, Ankara’s own view of Hezbollah inevitably changes. Hezbollah is no longer seen only as an Iranian proxy; it becomes part of a wider regional barrier against Israeli domination.
This does not mean Turkey will openly embrace Hezbollah. Ankara remains a NATO member, maintains complex economic and diplomatic ties with the West, and must manage its relations with Gulf states, the United States, and Europe. Turkey is unlikely to formally ally with Hezbollah or subordinate its policy to Iran’s regional agenda. But it may increasingly adopt a position of strategic tolerance. It may criticize Israeli operations against Hezbollah, oppose efforts to destroy the organization, and treat Hezbollah’s continued existence as necessary for regional balance. This would mark a significant shift from Turkey’s earlier suspicion toward the group.
The implications for Turkish foreign policy are substantial. First, Turkey may become more vocal in defending Lebanon’s sovereignty. Ankara can frame this not as support for Hezbollah but as opposition to Israeli occupation, intervention, and military expansion. This allows Turkey to avoid openly endorsing a non-state militia while still protecting the strategic environment in which Hezbollah operates.
Second, Turkey may deepen coordination with Iran on selected regional issues, even while preserving rivalry elsewhere. The U.S.–Iran deal creates a diplomatic opening in which Turkey could present itself as a stabilizing power. Ankara may support de-escalation, the reopening of Hormuz, reconstruction funds for Iran, and sanctions relief, because these steps reduce the risk of regional war. At the same time, Turkey will want to prevent Iran from monopolizing the benefits of the agreement. Turkish policymakers will likely seek economic opportunities in reconstruction, energy, trade, and transit routes.
Third, the agreement may strengthen Turkey’s argument that the Middle East cannot be governed through Israeli military superiority alone. For Ankara, the war demonstrated the limits of coercion. American and Israeli strikes damaged Iran but did not force Tehran to surrender. Iran retained nuclear leverage, preserved its regional links, and extracted a diplomatic framework that includes Lebanon. Turkey may interpret this as evidence that military escalation ultimately empowers resistance forces rather than eliminating them.
Fourth, the deal could sharpen Turkey’s tensions with Israel. If Israel refuses to accept the Lebanese provisions of the agreement and continues operations against Hezbollah, Ankara may accuse Israel of sabotaging regional peace. Turkish rhetoric could become harsher, especially if Israeli military action produces civilian casualties in Lebanon or threatens Syria. Erdoğan’s government would likely use such developments to reinforce its claim that Israel is the main source of regional disorder.
Fifth, Turkey may use the agreement to advance its own civilizational and geopolitical narrative. Erdoğan’s Turkey presents itself as the defender of Muslim societies against Western double standards and Israeli militarism. The survival of Iran after the war, the inclusion of Lebanon in the agreement, and the restraint imposed on Israel could all be folded into Ankara’s narrative that the region is moving away from Western-Israeli domination. In this narrative, Hezbollah becomes less a sectarian Shi‘i actor and more a symbol of resistance to Israeli power.
Yet this shift carries risks. Treating Hezbollah as a defensive buffer may help Turkey counterbalance Israel, but it also risks drawing Ankara closer to Iran’s regional logic. Hezbollah is not simply a Lebanese resistance movement; it is also an armed organization deeply embedded in Iran’s strategic network. If Turkey normalizes Hezbollah’s role too much, it may weaken its own commitment to state sovereignty and complicate its relations with Sunni Arab states, the United States, and Europe. Moreover, supporting Hezbollah indirectly could create contradictions in Turkey’s own policy toward Kurdish armed movements. Ankara cannot easily condemn non-state armed groups when they threaten Turkey while legitimizing them when they serve regional balancing purposes.
There is also the danger of strategic miscalculation. If Hezbollah provokes Israel or if Israel strikes Hezbollah and Iran responds, Turkey could find itself trapped between rhetorical solidarity and strategic caution. Ankara may want Hezbollah to survive as a deterrent, but it does not want a wider regional war that destabilizes Syria, threatens trade, increases refugee flows, or brings U.S. military pressure back into the region. Turkey’s ideal outcome is not Hezbollah’s victory over Israel but Hezbollah’s continued existence as a restraint on Israeli expansion.
The U.S.–Iran agreement therefore places Turkey in a complex position. Ankara welcomes de-escalation but worries about the new regional order that may emerge. It distrusts Iran’s ambitions but fears Israel’s militarized regional project more. It does not love Hezbollah but increasingly sees Hezbollah’s destruction as strategically dangerous. The result is a major transformation in Turkish thinking: Hezbollah is moving from the category of Iranian proxy to the category of regional buffer.
In the end, the agreement’s importance for Turkey lies less in its legal provisions than in its geopolitical meaning. It reveals that Iran, despite massive damage, remains a central regional actor. It shows that Hezbollah cannot be isolated from the broader balance of power. It demonstrates that Israel’s military campaigns have produced new alignments of fear and resistance. And it pushes Turkey to reassess old assumptions. For Ankara, the central question is no longer whether Hezbollah is ideologically acceptable. The question is whether the disappearance of Hezbollah would leave Israel unchecked. Increasingly, Turkey’s answer appears to be yes. That answer may shape Turkish foreign policy in the next phase of the Middle East crisis.
