EditAllies eye post-conflict Hormuz mission as Trump rejects help and keeps blockade in place
European leaders emphasize it is not support for the ongoing U.S. naval blockade of Iranian ports, but a mission aiming to restore freedom of navigation in the vital waterway
More than a dozen countries have signalled their willingness to join a multinational mission to safeguard shipping through the Strait of Hormuz once the current conflict winds down, according to British Prime Minister Keir Starmer. The announcement came after a high-level conference in Paris chaired by France and Britain, involving on video around 50 nations from Europe, Asia, and the Middle East.
The initiative is framed as strictly defensive and post-conflict: it would only activate after a lasting ceasefire or the full end of hostilities. European leaders emphasize it is not support for the ongoing U.S. naval blockade of Iranian ports, which they view as tantamount to entering the war. Instead, the mission aims to restore freedom of navigation in the vital waterway, which carries roughly one-fifth of the world’s oil and liquefied natural gas.
A narrow chokepoint in a wider war
The Strait of Hormuz, the narrow passage between the Persian Gulf and the Gulf of Oman, has been at the heart of escalating tensions since U.S. and Israeli airstrikes targeted Iran on 28 February. In response, Tehran largely closed the strait to non-Iranian vessels, laying mines and asserting control over transit routes. Shipping traffic plummeted more than 95 percent, from about 100–140 vessels daily to single digits in recent weeks, triggering spikes in global oil prices and insurance costs.
The U.S. responded with its own blockade of Iranian ports and coastal areas starting in mid-April, after peace talks in Islamabad collapsed without agreement. President Donald Trump has repeatedly framed the crisis in transactional terms, demanding Iran commit to abandoning its nuclear ambitions and cease using the strait “as a weapon.” He has offered political risk insurance through the U.S. International Development Finance Corporation to encourage maritime trade and, at times, floated U.S. Navy escorts – while simultaneously insisting the United States “does not need allies’ help” to enforce the blockade.
Trump’s approach reflects a continuation of his long-standing “maximum pressure” strategy toward Iran, first deployed during his first term (2017–2021) through sanctions and the 2018 withdrawal from the Iran nuclear deal. In 2026, it has evolved into direct military engagement and economic coercion. He has issued ultimatums – threatening strikes on Iranian power plants and infrastructure – while also announcing temporary ceasefires and floating new talks. Critics argue the administration underestimated Iran’s willingness to weaponize the strait, leading to a broader energy crisis despite U.S. claims of having degraded Iranian naval capabilities.
Trump’s diplomacy: “America First” meets global energy realities
From the outset of the 2026 escalation, Trump has pursued a unilateral, deal-oriented style. He celebrated Iran’s 17 April announcement that the strait was “fully open” to commercial vessels, only to clarify minutes later that the U.S. blockade on Iranian ships and ports would remain “in full force” until a comprehensive agreement is reached.
This mirrors his first-term playbook: leverage economic pain to force concessions, while downplaying the need for multilateral buy-in. Earlier in the crisis, he called on NATO allies and even China to help reopen the strait—only to reverse course and tell allies to “stay away” from the blockade. European capitals, wary of being drawn into active combat, have refused participation in enforcement actions but are now positioning themselves for a stabilizing role once fighting subsides.
French President Emmanuel Macron and Starmer have stressed opposition to any “privatisation” of the strait or imposition of tolls, signalling a desire for a rules-based, collective approach rather than U.S.- or Iran-dominated control.
Regional flashpoint and the path forward
The crisis has ripple effects across the Gulf. Iran has sustained some oil exports – primarily to China – via shadow fleets, while Gulf Arab states worry about retaliatory strikes on their own energy infrastructure. Shipping companies remain hesitant despite Iran’s reopening announcement, citing lingering risks from mines, unclear rules of engagement, and the U.S. blockade.
A senior French official described the proposed mission as potentially including intelligence sharing, mine clearance, military escorts for merchant vessels, and coordination with neighbouring countries. Details will be fleshed out at a follow-on military planning conference in London next week. Germany’s Chancellor Friedrich Merz indicated Berlin is ready to contribute, provided there is a “secure legal basis,” such as a U.N. resolution, and expressed hope that U.S. input could still be incorporated without straining transatlantic ties.
Diplomats caution that the mission may never fully materialize if normal shipping resumes organically. Yet insurers and shipping firms are expected to welcome the reassurance of an international presence during any fragile transition.
As Trump continues his bilateral pressure campaign – betting that economic isolation will bring Iran back to the table – Europe and a broad coalition of partners are quietly preparing an alternative: a collective, post-conflict framework to keep the strait open for all. Whether this diplomatic divergence eases or exacerbates tensions between Washington and its traditional allies remains to be seen. For now, the world’s most critical energy artery hangs in a delicate balance between unilateral power plays and multilateral stabilisation efforts.
