EditMiddle East escalation puts Southeast Europe’s NATO infrastructure in the spotlight
As retaliation unfolds in the Gulf, NATO facilities in the Eastern Mediterranean to the Black Sea emerge as potential targets
The joint Israel-United States operation against targets in Iran has opened a new phase of regional instability, with Tehran responding through retaliatory measures that, in the first wave, were directed primarily against Israeli targets and U.S. facilities in the Middle East, in countries hosting American military presence.
In Southeast Europe authorities recorded a heightened level of alert and tightened security measures at critical hubs, with increased vigilance at Souda Bay in Crete, one of the most critical U.S. and NATO naval-air hubs in the Eastern Mediterranean.
The developments bring back into focus a strategically significant question: how the extensive network of U.S. and NATO facilities stretching from the Eastern Mediterranean to the Black Sea resist to asymmetric pressure – as Middle Eastern conflicts acquire duration and multiple layers.
In Greece, Souda remains the primary high-value hub for naval and air flows in the Eastern Mediterranean, with air facilities located on the Akrotiri peninsula in Chania, Crete. The port of Alexandroupolis has emerged as a key transit point for matériel towards NATO’s eastern flank. Larissa, hosting intelligence, surveillance and reconnaissance (ISR) missions and assets such as MQ-9 drones, and Stefanovikio, serving as a training and support hub, complete a network of facilities that may not always make headlines but gain weight when the broader region enters a prolonged crisis phase.
Along the northern axis of the Black Sea, Romania, with the Mihail Kogălniceanu air base and the Deveselu base, where the Aegis Ashore system is deployed, provides NATO’s architecture with a critical element of defence and operational readiness. Bulgaria, through the Novo Selo Training Area, the Bezmer air base and the Aytos Logistics Center, functions as a space for training, rotational presence and logistics. In the Western Balkans, Camp Bondsteel in Kosovo and the role of KFOR continue to constitute a stabilisation mechanism whose importance extends beyond daily headlines, particularly when major crises tend to export instability to neighbouring regions.
At the southern edge of the Eastern Mediterranean, Cyprus – though not a NATO member, hosts the British Sovereign Base Areas, with the RAF base at Akrotiri as their spearhead. Due to geography, they are directly linked to the region’s operational reality.
The structure of this network illustrates why Southeast Europe functions primarily as strategic depth: it hosts hubs for refuelling, redeployment, support and flow management, rather than points of first launch for offensive operations.
Here lies the emerging trend. As crises in the Middle East take on a cyclical character – strike, retaliation, renewed pressure, support infrastructure outside the immediate theatre of operations acquires a dual role. On the one hand, it strengthens deterrence and operational resilience for the United States and NATO. On the other, it can be drawn into lower-scale but symbolically significant targeting logics, including cyberattacks, harassment operations, attempts to disrupt supply chains or actions by third-party networks acting as force multipliers of pressure.
Under these conditions, the question which facilities might be theoretically more exposed is determined not only by geography, but by a combination of visibility, operational relevance and political cost. Souda and RAF Akrotiri carry high visibility and proximity to the Eastern Mediterranean. Alexandroupolis gains specific weight as a logistical hub towards the eastern flank. Romania, with Aegis Ashore, holds particular weight within NATO’s architecture.
By contrast, facilities primarily associated with training and rotational presence, particularly along parts of the Balkan axis, tend to be of lower “return” as targets for direct demonstrations of force, especially if Tehran seeks controlled escalation rather than generalised confrontation.
Within the same framework lies the discussion surrounding Turkey. The fact that Turkish infrastructure, such as the Incirlik air base and the Kürecik radar station, did not feature in the first wave of Iranian retaliation relates primarily to the initial focus of Tehran’s strikes on U.S. facilities in the Middle East rather than on European soil.
Beyond that, Ankara moved swiftly at the level of public positioning, rejecting claims that its territory or airspace had been used for operations against Iran, seeking to disconnect Turkish territory from the chain of causality of escalation. Moreover, a strike inside Turkey would entail a higher risk of political and strategic escalation, as it would directly affect the territory of a NATO member state with multiple international ramifications.
Finally, the Turkey-Iran relationship remains a mixture of competition and coordination across regional theatres. At a time when Tehran requires channels and room for manoeuvre, this functions as an additional deterrent factor against exporting retaliation at that level.
For Greece and Southeastern Europe as a whole, the practical conclusion is clear: the region is not on the front lines of direct missile exchanges, but it is increasingly embedded in the logic of network conflicts. The bases and facilities here form the backbone of Western operational resilience, and therefore their security depends not only on air defense and alert protocols, but on infrastructure resilience, counter-cyber defense, information management and – most importantly – on whether the crisis will remain limited or turn into a protracted all-out confrontation.

Its presence at the base, as already announced, is for the purpose of refueling. The USS Gerald R. Ford (CVN 78) is the newest nuclear-powered aircraft carrier of the United States, having entered service in 2017. It is capable of operating for almost 20 years without fuel while the supplies for the crew are large. 4,500 people serve on the USS Gerald R. Ford (CVN 78) which is 333 meters long and 78 meters wide and can sail at 30 knots. The strike force it carries is divided into six aircraft squadrons, totaling 75. EPA/Pattakos Petros
