Allies Discuss Defensive Naval Mission to Secure Strait of Hormuz

Allies of the United States are proposing a defensive naval mission to restore safe navigation through the Strait of Hormuz, a key oil-shipping lane, after a tentative cease-fire deal with Iran. The plan, announced by France, the United Kingdom, Germany, Japan, Italy and later joined by Canada, calls for mine-clearance operations and limited escort vessels to reassure commercial shipping and insurers.

French President Emmanuel Macron, who first suggested the idea in March, said France could deploy its aircraft carrier Charles de Gaulle, fighter aircraft and frigates within days, pending requests from regional partners. The United Kingdom highlighted its Royal Fleet Auxiliary vessel RFA Lyme Bay as ready for deployment, and other NATO members such as the Netherlands and Italy have indicated they could contribute assets.

The mission would focus on removing underwater explosives that could be triggered by sound, movement or light, and on providing a limited defensive presence to deter potential attacks. Analysts note that the need for such a presence would diminish if the cease-fire holds, but a European naval presence could still offer security benefits and signal commitment to Gulf states.

"Once there is a ceasefire, the need for a naval mission is significantly reduced," said Max Bergmann, an analyst at the Center for Strategic and International Studies. "A U.K.-French naval presence will no doubt have some security benefits. It might raise the stakes for Iran to rekindle the war; it demonstrates European commitment to Gulf states; and it might reassure shipping and insurance companies," he added.

The proposal follows joint planning that involved more than three dozen countries, including Australia, South Korea, Japan, Bahrain and Qatar, reflecting broad international interest in securing the waterway.
