European Allies Pledge Support for Iran Deal if Trump Secures Solid Agreement

At the G7 summit in Évian-les-Bains, France, on June 15-16, 2026, European allies expressed conditional willingness to assist President Donald Trump with implementing an Iran agreement, particularly regarding mine removal from the Strait of Hormuz. French President Emmanuel Macron indicated readiness to rapidly deploy fighter jets and frigates, contingent upon requests from the United States, Iran, and Oman. British officials stated their country "stands ready" to send assets to the region, while German Chancellor Friedrich Merz signaled support pending "necessary conditions" being met. Italian Prime Minister Giorgia Meloni pledged Italy's continued contribution to trade security missions but emphasized the need for lasting solutions in Gaza and Lebanon.

The European response, however, reflects significant caution regarding the Trump administration's unreleased Iran memorandum of understanding, scheduled to be signed on Friday. Trump prioritized reopening the Strait of Hormuz during bilateral and multilateral meetings, stressing the strategic importance of clearing mines from the waterway through which approximately one-fifth of global oil flows. A senior Trump administration official characterized international participation as "a very helpful thing to get things back to normal as quickly as possible," acknowledging that restoration of normal shipping operations could take weeks.

Experts note that European hesitation stems from historical experience with Iran negotiations and concerns about being held responsible for outcomes beyond their control. Suzanne Maloney of the Brookings Institution observed that Europeans are wary of bearing liability for an agreement they did not negotiate. The Middle East conflict has disrupted global energy markets, with particularly acute impacts on European nations highly dependent on the strait. While the war has already prompted France and Britain to advance multinational maritime security missions, any substantial European commitment hinges on the Trump administration releasing full details of the Iran agreement and demonstrating genuine Iranian compliance.
