With U.S.-Iran peace efforts stalled once again, Europe’s position is coming into focus: It is preparing for the next phase of the crisis without joining the war. Military and diplomatic moves across the continent over the past month—from Britain and Bulgaria granting U.S. forces access to air bases and logistical hubs to France and Germany pulling key naval assets out of the Middle East—point to caution rather than commitment.

European governments neither want another war nor possess the independent capacity or political will to take the initiative. If the conflict escalates, they appear prepared to offer only limited, indirect support centered on logistics and damage control. Some countries will quietly ease the way for American operations in return for tangible benefits; others will reduce their presence and try to contain the fallout.

Recent military activity has made Europe’s divisions difficult to ignore. In the east, Bulgaria has opened its airports and infrastructure with few meaningful restrictions, effectively turning the country into a refueling and transit bridge for American aircraft. This is not merely a technical decision. Officials in the region calculate that closer alignment with Washington could secure a more durable U.S. military presence around the Black Sea while bringing additional weapons and economic concessions.

Ukraine, meanwhile, has widened the theater by striking an Iranian commercial vessel in the Caspian Sea, demonstrating its willingness to open a northern front when doing so serves its interests. For these eastern European governments, geographic distance from the Gulf and a longstanding dependence on the United States for security make the costs of helping Washington relatively low—and the potential rewards appealing.

Western Europe is moving in the opposite direction. France and Germany have withdrawn key naval assets from the region and adopted a wait-and-see posture, making further involvement contingent on a ceasefire. Paris and London have said that any contribution would be limited to clearing mines and protecting commercial shipping in the Strait of Hormuz once tensions begin to ease. Neither intends to join the fighting.

Italy, by contrast, has concentrated on deploying air-defense capabilities to Saudi Arabia, Bahrain, and Kuwait, reinforcing the defensive perimeter around U.S. forces and their regional partners in a manner reminiscent of the forty-day conflict of the previous decade. These governments would rather remain at the edges of the conflict until the shooting stops, then help stabilize whatever remains.

That posture reflects the bind Europe now faces. Any sharp escalation threatens to deepen the energy crisis still weighing on the continent’s economies, many of which have yet to recover fully from earlier shocks. Dependence on maritime trade routes and vulnerable supply lines looms over European decision-making. At the same time, the need to preserve the strategic relationship with the United States pushes governments toward at least symbolic and logistical alignment, if only to limit political damage to the alliance. Europe is left performing a familiar balancing act between economic self-preservation and alliance management.

Some observers contend that the crisis could finally compel Europe to reduce its military dependence on the United States and accelerate defense integration. In practice, divergent national interests have prevented such coherence from emerging. European governments are willing to adopt defensive measures to protect energy supplies and shipping lanes, but they draw a firm line at offensive operations, ground invasions, or attacks on infrastructure. The Belgian prime minister’s recent warning that NATO will not support countries that enter wars on their own and then expect assistance captures the prevailing mood. Competing interests continue to produce different national responses, placing meaningful collective action beyond reach.

If the next phase of the conflict remains confined to the Strait of Hormuz, a naval blockade, and attacks on offensive capabilities, most European states are likely to repeat the pattern established during the earlier forty-day war: strengthening the defensive perimeter and providing logistical assistance to the United States without entering the fight.

A handful of eastern European countries, notably Ukraine and Bulgaria, may be willing to go further if the economic and military rewards are clear. But if the conflict expands to include ground operations or large-scale attacks on infrastructure, western European powers will almost certainly retreat further and try to reopen channels between Tehran and Washington. The east-west divide in risk tolerance is structural and unlikely to disappear anytime soon.

Europe’s posture also has strategic implications for Iran. Raising the costs of logistical support—particularly for the more willing eastern partners—may be one of Tehran’s more effective means of disrupting this pattern of facilitation. The arrangement is most vulnerable in countries that can currently assist the United States at relatively little cost while expecting financial and military benefits in return.

Even so, Europe’s broader preference remains one of strategic passivity: managing the consequences of war rather than participating directly in offensive operations. That approach stems less from confidence than from a sober calculation of costs and benefits. For now, Europe lacks both the capacity and the political appetite to act as an independent, assertive power in the Middle East. It can help sustain an American campaign, cushion some of its effects, and perhaps assist with the cleanup. What it cannot—or will not—do is shape the war itself.
