Donald Trump Issues Ultimatum to Europe Over Support for Securing Hormuz

The fragile ceasefire between the United States and Iran has created a narrow opening for diplomacy, even as tensions remain high.

With global oil flows disrupted, Washington is now pushing its European allies to act swiftly on securing the Strait of Hormuz — one of the world’s most vital energy corridors. The Donald Trump administration has made it clear that symbolic backing is no longer sufficient.

According to Bloomberg, US officials have asked European partners to present detailed, actionable plans within days on how they would help safeguard navigation through Hormuz if hostilities subside. The issue was discussed in high-level meetings across the White House, the Pentagon and the State Department, including Trump’s interaction with Mark Rutte.

Rutte has also conveyed to several capitals that Washington expects firm commitments within days, Reuters reported, underscoring the urgency behind the push.

Earlier, a UK-led coalition involving more than 40 countries — including European nations, Japan and Canada — signalled readiness to support efforts to reopen Hormuz, a route that carries nearly a fifth of global oil and gas supplies. However, the situation on the ground remains unstable. Despite a 14-day ceasefire announcement, clashes have not entirely ceased. Tehran has cited continued Israeli strikes in Lebanon as a violation, while shipping activity through the strait has yet to return to normal levels.

Iranian Parliament Speaker Mohammad Bagher Qalibaf has stressed that developments in Lebanon and across what Iran calls the “Resistance Axis” are intrinsically linked to the ceasefire framework, adding further complexity to the situation.

This gap between commitments and reality is driving Washington’s urgency. US officials want to ensure that if the ceasefire holds, maritime traffic through Hormuz can resume without delay.

NATO under strain

The developments have also exposed divisions within NATO. Several European members have been cautious about backing US military actions against Iran and hesitant to engage while hostilities persist.

Trump has publicly criticised that approach. Following his meeting with Rutte, he remarked that NATO had failed to step up when needed, reflecting growing frustration in Washington. The US President has repeatedly questioned the alliance’s role and hinted at reassessing American commitments.

For Rutte, the situation presents a delicate balancing act, as he navigates tensions over the Iran crisis alongside broader disagreements on defence spending and alliance priorities.

Senior US officials, including Secretary of State Marco Rubio, have also signalled that greater allied support is expected, warning that Washington could reconsider its posture if contributions fall short.

Meanwhile, diplomatic channels remain active. Vice President JD Vance is expected to lead a US delegation to Islamabad for talks with Iranian representatives aimed at securing a more durable truce.

For now, much depends on whether the ceasefire holds — and how quickly allies translate commitments into action. The Strait of Hormuz remains both a strategic lifeline and a geopolitical flashpoint.
