NATO Secretary General Mark Rutte has privately informed several European capitals that U.S. President Donald Trump expects firm and immediate commitments from allies to help secure the Strait of Hormuz, according to three European diplomats familiar with the discussions.

The request, delivered with unusual urgency, comes just days after Rutte met Trump in Washington amid deepening tensions within the alliance and growing unease about the direction of the U.S.-Iran conflict.

The talks took place against the backdrop of the ongoing war with Iran—an escalation that has rattled global markets, strained historic partnerships, and placed renewed focus on one of the world’s most critical maritime chokepoints. Rutte’s visit to the White House came at a time when NATO members were already divided over the scope of their involvement, and Trump’s latest push has triggered fresh anxiety across European diplomatic circles.

A NATO spokesperson, Allison Hart, confirmed that Rutte has been in active conversation with alliance members since returning from Washington. She emphasized that the United States is seeking “concrete commitments and action” to ensure freedom of navigation through the Strait of Hormuz, where shipping traffic has been severely disrupted due to the conflict. Although the U.S. paused its strikes under a temporary two-week ceasefire, the strategic waterway remains largely shut, and the political fallout continues to reverberate.

Trump, who has repeatedly criticized NATO in recent months, escalated his attacks again after the meeting. In a sharply worded Truth Social post written entirely in capital letters, he accused the alliance of being unreliable, declaring that NATO “wasn’t there when we needed them, and they won’t be there if we need them again.” His frustration centers on what he views as insufficient allied support for the U.S.-Israeli operation in Iran—an operation many European leaders say they were neither consulted on nor briefed about beforehand.

One senior European diplomat noted that while allies “recognize the frustration in Washington,” the U.S. had launched and expanded its campaign without coordinating with NATO partners. “NATO as an institution won’t take part in the Iran war,” the diplomat added, “but allies are prepared to contribute to long-term solutions for Hormuz. That could be useful, especially with negotiations ongoing.”

Rutte, who has gained a reputation in Europe as a “Trump whisperer” for his relatively warm relationship with the U.S. president, told CNN that he understood Trump’s frustrations. But his reassurances did little to calm nerves in Europe. A high-ranking European official described the mood bluntly: “The NATO community is more worried than confident. The meeting did not take the worry away.”

Behind the scenes, early planning is already underway. Britain has taken the lead in assembling a coalition of roughly 40 countries to design a coordinated military and diplomatic strategy to reopen the Strait of Hormuz. But officials caution that meaningful progress is unlikely in the near term. French President Emmanuel Macron announced that around 15 nations are working to help restore commercial traffic through the strait, yet key political obstacles remain.

France’s foreign minister, Jean-Noel Barrot, said that any full reopening will require a durable settlement between the United States and Iran—something that still appears distant despite the temporary ceasefire. Meanwhile, Italy and Britain both rejected Iran’s suggestion that it may seek to impose a toll on vessels crossing Hormuz, calling the move unacceptable and destabilizing.

Another European diplomat underscored the delicate balancing act facing the alliance. “We understand the urgency on the U.S. side, and Rutte is clearly trying to position himself as useful in that conversation,” the diplomat said. “We are prepared to say the right things and eventually take the right actions. But what really matters is not simply pleasing the United States—it’s ensuring the right conditions for a sustainable solution.”

For now, uncertainty dominates. Diplomatic efforts continue, military planning intensifies, and the future of the crucial maritime corridor remains unclear. What is clear, however, is that the pressure is mounting on NATO members to respond swiftly—and that any misstep may carry global consequences at a moment when the alliance is already under unprecedented strain.
