Europe's Collective 'No': Why America's Closest Allies Won't Help Reopen the Strait of Hormuz

Eighteen days into Operation Epic Fury, President Donald Trump faces a crisis he did not anticipate: not from Iran's mines or missiles, but from the silence of his own allies. In a sweeping diplomatic rebuff that has no modern precedent in transatlantic relations, virtually every major European power — along with key partners in Asia and the Pacific — has refused Trump's demand to send warships to help reopen the Strait of Hormuz, the narrow waterway through which one-fifth of the world's oil supply once flowed freely [1][2].

The refusal is not merely a policy disagreement. It is a structural rejection of American leadership over a war most allies believe they were never consulted about, never endorsed, and now refuse to own.

The Demand

On March 14, Trump called on China, France, Japan, South Korea, the United Kingdom, and other nations to send naval assets to the Strait of Hormuz, arguing that countries that benefit from the waterway's oil flows have a duty to help secure it [3]. In an interview with the Financial Times, he warned that "it will be very bad for the future of NATO" if countries fail to participate, adding ominously, "We will remember" [4].

The Trump administration's wish list was ambitious: the U.K., France, Germany, Italy, Australia, Canada, the Gulf states, and Jordan were all expected to contribute to a coalition that would escort tankers and clear the mines Iran has seeded across the strait since early March [5]. Trump told reporters he had spoken to French President Emmanuel Macron about escorting tankers and predicted "I think he's going to help" [6].

He was wrong.

The Rebuff

At a gathering of EU foreign ministers in Brussels on March 16–17, the rejection was swift and comprehensive.

Germany delivered the sharpest reply. Defence Minister Boris Pistorius said there would be "no military participation" from Berlin, asking pointedly: "What does Trump expect a handful or two handfuls of European frigates to do in the Strait of Hormuz that the powerful US Navy cannot do?" [1] Chancellor Friedrich Merz confirmed Germany would not participate in any Hormuz mission as long as the war continues [5].

The United Kingdom — Washington's closest security partner — was only marginally more diplomatic. Prime Minister Keir Starmer said reopening the strait "is not a simple task" and that the UK was "working with all of our allies" to develop "a viable collective plan." But he drew a firm line: "Let me be clear: that won't be, and it's never been envisioned to be, a NATO mission" [2]. The UK did signal it might offer mine-hunting drones already stationed in the region — a token contribution that fell far short of Trump's expectations [5].

Finland's Foreign Minister Elina Valtonen captured the prevailing European sentiment: "We unfortunately have a hot war waging in Europe, too, and that is certainly our first priority" [7].

Greece, Spain, Italy, and Ireland all refused military involvement. Spain's Defense Minister stressed the country would "never accept measures that add tension or escalate the situation" [8]. The EU's foreign policy chief, Kaja Kallas, summarized the consensus: "There was no appetite from the member states to do that. Nobody wants to go actively in this war" [7].

Beyond Europe, the picture was no better. Australia, Japan, Poland, and Sweden all said they had no intention of sending warships [1]. New Zealand indicated it had not even received a formal request [8].

Why Europe Said No

The refusal rests on three interlocking grievances that have been building since Operation Epic Fury began on February 28.

"Not Our War"

European leaders have consistently framed the U.S.-Israeli military campaign against Iran as a unilateral American decision made without allied consultation. The strikes that killed Supreme Leader Ali Khamenei on February 28 were not coordinated with NATO, and no Article 5 consultation was sought. From Europe's perspective, Trump is now asking allies to clean up the consequences of a war they had no say in starting.

Kallas put it bluntly: "Europe has no interest in an open-ended war" [1]. The subtext is clear — if Washington wanted European participation, it should have sought European consent before launching the campaign.

Ukraine Comes First

For NATO's European members, the Russian threat is existential in a way the Hormuz crisis is not. Finland, the Baltic states, Poland, and others view their military resources as committed to deterring Moscow. Valtonen's statement that Europe has "a hot war waging" on its doorstep reflects a genuine strategic calculation: every frigate sent to the Persian Gulf is one fewer available for Baltic Sea patrols or Black Sea deterrence [7].

Transactional Leadership Doesn't Inspire Solidarity

Analysts note that Trump's approach to alliances — framing NATO as a protection racket where members "pay back" the United States — undercuts his ability to rally coalitions when he needs them. As analyst Giuseppe Spatafora observed, Trump frames NATO transactionally rather than as a unified alliance, which fundamentally undermines his appeal for solidarity [7]. Threatening allies with "a very bad future for NATO" while simultaneously demanding their help is a diplomatic strategy that, by March 2026, has produced zero confirmed participants [4].

The Diplomatic Back Channel

While publicly rejecting military action, some European nations have quietly pursued a parallel strategy: negotiating directly with Tehran for safe passage.

France and Italy opened talks with Iran as early as March 13, seeking to secure the transit of their flagged vessels through the strait [9]. President Macron confirmed he spoke with Iranian President Masoud Pezeshkian, telling him that Iran "needs to guarantee freedom of navigation to put an end to the closure of the Strait of Hormuz" [6]. Italy's Foreign Ministry carefully characterized its contacts as efforts to "favor the conditions for a general military de-escalation" [9].

These bilateral negotiations represent a significant departure from the unified Western front Trump has demanded. Rather than confronting Iran militarily alongside the United States, European powers are effectively seeking separate accommodations — a strategy that implicitly legitimizes Iran's control over the strait.

Iran's Strategic Gambit: Passage for Yuan

Iran has turned the Hormuz blockade into something far more consequential than a military tactic. Through a selective passage policy, Tehran is actively reshaping the geopolitical and financial architecture of global energy trade.

Since early March, Iran has granted safe passage to ships from Pakistan, India, Turkey, and — most significantly — China, while maintaining the blockade against Western-flagged vessels [10]. The policy's most disruptive element is the reported condition that oil transiting the strait must be traded in Chinese yuan rather than U.S. dollars [11].

Between 11.7 and 16.5 million barrels of Iranian crude have reportedly transited the strait to China under IRGC naval protection, with all transactions settled in yuan [11]. Iran is also negotiating to allow Qatari LNG carriers through under similar terms [12].

This yuan-for-passage arrangement strikes at the heart of the petrodollar system — the decades-old convention that oil is globally traded in U.S. dollars. If sustained or expanded, it could redirect structural demand away from the dollar and toward China's currency, weakening one of the foundational pillars of American financial hegemony [11].

The Mine-Clearing Problem

Even if Trump were to assemble a willing coalition, the practical challenge of reopening the strait is immense. Iran has deployed naval mines throughout the waterway, and clearing them is a slow, painstaking process.

The relevant precedent is sobering: after the 1991 Gulf War, it took the United States and its allies 51 days to clear 907 mines off the Kuwaiti coast — and that operation began only after hostilities had ended [5]. Attempting mine clearance under active fire from Iranian anti-ship missiles and fast-attack boats would be exponentially more dangerous.

The U.S. Navy's own mine-countermeasure capacity has atrophied over decades of underinvestment. The fleet of dedicated minesweepers has shrunk, and the Littoral Combat Ship's mine-warfare module — designed to fill the gap — has been plagued by development delays [13]. The UK's offer of mine-hunting drones, while symbolically important, does not come close to addressing the scale of the problem.

Oil Markets in Turmoil

The Hormuz closure has produced the largest oil supply disruption in modern history. WTI crude oil, which traded below $57 per barrel in mid-December 2025, surged past $94 by March 9 — a roughly 65% increase in under three months. On March 9, Brent crude briefly topped $100 before a volatile retreat [14].

The price shock has cascading effects across the global economy. European gas prices have jumped approximately 75% since the war began. The UK government announced £53 million in emergency support for households facing heating oil price increases [8]. The IEA has released a record 400 million barrels from emergency reserves, but analysts warn that strategic releases cannot compensate for the sustained loss of 16 million barrels per day that normally transit the strait [15].

What Comes Next

Trump's coalition-building effort has produced what one CNBC headline called a parade of nations that are "less than enthusiastic" [16]. On March 16, Trump insisted that "numerous countries" had told him help was "on their way," but no country has publicly confirmed participation [6].

The gap between Trump's rhetoric and reality leaves three possible scenarios.

Scenario one: The United States attempts to clear mines and escort tankers unilaterally, accepting the military risk and cost alone. This would further strain an already stretched Navy and risk direct confrontation with Iranian forces in confined waters.

Scenario two: European and Asian nations continue bilateral negotiations with Tehran, gradually normalizing Iran's selective passage regime and its yuan-denominated trade conditions. This path avoids military escalation but fundamentally undermines American strategic interests — and the dollar's role in global energy markets.

Scenario three: The Hormuz crisis becomes the lever that forces a broader ceasefire. With oil above $90, global supply chains fracturing, and no coalition materializing, the economic pressure on all parties — including the United States — may ultimately accomplish what diplomacy has not.

For now, America's allies have made their position clear. They are willing to talk about the Strait of Hormuz. They are willing to negotiate with Iran about it. They are willing to express concern about oil prices at EU summits. What they are not willing to do is send their sailors into a war zone to fight a war they believe the United States chose to start alone.

The question is whether Trump will hear their message — or whether the transatlantic alliance, already strained by years of mutual grievance, will fracture under the weight of a crisis that has exposed just how little solidarity remains.
