Managing Spillover:
Türkiye–EU and the Iran Crisis
The US-Israel military campaign against Iran has sent shockwaves far beyond the battlefield. As strikes intensify and retaliation escalates, policymakers across the region and beyond are grappling with a cascading set of secondary crises—none more pressing than the spectre of mass displacement.
Among the first to mobilise, Türkiye has emerged as an early coordination hub in European Union contingency planning. This analysis does not aim to forecast precise numbers; rather, it seeks to make visible the underlying logic of risk, map plausible scenarios, and assess available policy options through the lens of official statements and emerging field indicators.
Over the last 48 hours, the common keywords highlighted in both Brussels and Ankara – “diplomacy,” “basis for negotiation,” “close coordination,” “regional stability,” and “preparedness” – indicate that the crisis is being interpreted not merely as a military file, but as a set of regional risks managed through its spillover effects.
Indeed, the statement from the Presidency of the Republic of Türkiye’s Directorate of Communications regarding the meeting conveys that President Erdoğan invited “all parties to return to the basis of diplomacy and negotiation” and emphasised that “maintaining close coordination between Türkiye and the EU is essential.” The same axis is evident in European Commission President Ursula von der Leyen’s post regarding her meeting with Erdoğan: “close coordination,” Türkiye’s readiness for mediation, and the emphasis on “preparedness” against the potential impacts of the crisis on migration are mentioned in conjunction.
At this point, there is a critical distinction to make: the heavy diplomatic traffic and the language of “preparedness” do not constitute evidence that a mass migration has already commenced. They simply signify a common practice in crisis governance by states and institutions: scenario planning and establishing coordination early, before an influx occurs. Keeping this distinction clear is essential to avoid adopting alarmist tropes.
Why Does the “Spillover” Threshold Move the Migration File Forward?
Behind the European Union’s (EU) ongoing contacts with Gulf capitals and the Eastern Mediterranean line lies the potential for the conflict to expand geographically. As a reflection of this “spillover” risk in Europe’s immediate neighbourhood, news reports indicating that the RAF Akrotiri base in Greek-Administrated Cyprus was targeted by a suspected drone strike demonstrated that regional tensions could touch upon the periphery of EU member states.
What matters here is not the isolated security incident itself, but the signalling function it performs within European governance systems. When conflict proximity increases, especially through incidents touching EU territory or military infrastructure, migration risk becomes securitised earlier in the policy cycle. In such moments, mobility is framed less as a humanitarian aftermath and more as a strategic contingency. The spillover threshold thus accelerates coordination by compressing the temporal gap between conflict escalation and border-management planning.
The Migration Mechanism: Through Which Channels Could Mobility Arise from Iran?
The migration implications of an Iran-centred conflict extend beyond the movement of Iranian citizens. Iran has long hosted a large Afghan population, and throughout 2025 there have been significant reports of mass and sometimes coercive returns of Afghans from Iran (and Pakistan). Many returnees face severe vulnerabilities in Afghanistan, particularly regarding livelihoods, housing, and women’s access to education and employment.
In a renewed escalation scenario, two dynamics become critical. First, as security and economic pressures intensify within Iran, precarious groups—especially Afghans—may mobilise more rapidly. Second, this mobility would initially manifest not as direct flows to Europe, but as regional “pooling” in neighbouring areas.
Rather than a linear “Iran crisis = immediate influx to Europe” dynamic, a more plausible mechanism involves phased displacement. Primary displacement would likely occur over short distances, triggered by immediate insecurity or economic shock. Secondary mobility—potentially onward toward Europe—would depend on prolonged instability, limited livelihoods, and weakened regional governance capacity. This sequencing clarifies why early coordination reflects layered risk awareness rather than imminent mass arrival.
The Türkiye Nexus: Why is “Close Coordination” So Critical?
Türkiye’s official framework presents a decisive “mainline” in this analysis: Ankara emphasises diplomacy and negotiation while avoiding becoming a party to the war in the crisis; simultaneously, it calls for close coordination with the EU. These dual emphases are not contradictory; rather, they are parts of the same strategic logic. For Türkiye, the issue is not merely the magnitude of potential mobility but maintaining a regular border governance framework that preserves humanitarian standards while limiting the costs of uncontrolled routes on security, public order, and local capacity.
- This approach extends beyond simple border control. Combating disinformation, preventing public panic, strengthening field-level administrative capacity, and maintaining diplomatic coordination form part of a unified crisis-management strategy. In this context, there is no contradiction between Türkiye’s rejection of unfounded claims circulating in certain media outlets, such as allegations that “points within Türkiye’s borders were struck”, and its simultaneous call for close coordination with the EU. Rather, these actions represent two complementary pillars of crisis communication: containing exaggerated narratives that could fuel domestic panic and political pressure, while proactively coordinating with the EU in anticipation of Türkiye potentially serving as an initial area of regional accumulation in emerging mobility scenarios.
The inclusion of the emphasis on “preparedness” against migration impacts in Von der Leyen’s message regarding her meeting with Erdoğan, along with the reference stating “we are already working closely in Syria,” indicates that the EU is proceeding with a similar logic: the need to adapt the existing Türkiye–EU migration governance file (coordination, capacity, support) to potential new shocks rather than inventing a new mechanism.
This coordination logic reflects structural interdependence rather than political preference. Due to geography, existing hosting capacity, and prior institutional arrangements under the Türkiye–EU migration framework, Türkiye occupies a pivotal position in any Eastern Mediterranean displacement scenario. In crisis governance terms, early engagement with Ankara represents path dependency: existing coordination mechanisms are more readily adapted to new shocks than entirely new governance structures can be constructed under time pressure.
Strategic Outlook
Ultimately, the migration dimension of the Iran crisis is not an automatic consequence of war, but a function of governance under stress. Whether displacement remains regionally contained or evolves into broader mobility pressure will depend less on battlefield developments alone and more on institutional resilience, protection standards, and the ability of regional actors to manage shocks without securitising them prematurely.
The early Türkiye–EU coordination should therefore be read not as a reaction to imminent mass movement, but as a preventive governance reflex shaped by geography, experience, and interdependence. In an environment where escalation can compress timelines and destabilise fragile hosting arrangements, preparedness is not alarmism; it is risk management.
The decisive question moving forward is not whether migration will occur, but whether it will be managed in a manner that preserves humanitarian standards while preventing secondary crises of political panic and policy overreach. In this respect, the Iran file is also a test of regional crisis governance: not only of military restraint, but of whether neighbouring actors can stabilise mobility risks before they harden into structural displacement patterns.
