An interim agreement between the United States and Iran transformed the Group of Seven summit in Évian from a showcase of Western unity into a largely American diplomatic moment. Washington presented the deal as a framework to end hostilities and reopen the Strait of Hormuz — and in doing so, it appeared to take the wind out of any European-led maritime operation. But the fundamental question remains unanswered: Can the strait be reopened in a way that is safe, lasting, and acceptable to commercial shipping operators, insurers, Gulf nations, and European governments?
In the lead-up to and during the summit, European leaders had floated the idea of taking a maritime role in the strait, potentially including mine-clearing operations, vessel escorts, and efforts to restore freedom of navigation. The motivation was both strategic and economic. The Strait of Hormuz is not just a regional bottleneck — it is a global one. Any extended disruption there would ripple outward, driving up oil prices, shipping costs, insurance rates, and inflation well beyond the Middle East.
The US-Iran memorandum, however, shifted the focus. Rather than a European-backed operation moving toward action, attention turned to whether Washington and Tehran had found a formula to reopen the waterway without requiring a foreign naval force as the central enforcement mechanism.
A US State Department adviser for Middle East affairs named Willian, who attended the G7 and asked to be identified only by his first name, said the European maritime option had already been passed by.
