US President Donald Trump has reportedly threatened to suspend weapons support for Ukraine as a means of pressuring European allies to join a US-led initiative aimed at reopening the Strait of Hormuz. According to reports, the warning was directed at NATO members who have so far resisted calls to participate in naval operations in the region, with some European governments arguing that the conflict does not directly concern them.
The pressure tactic is tied to the PURL programme, a NATO-backed weapons procurement mechanism funded by European nations to support Ukraine. Trump is said to have indicated that continued US involvement in this initiative could be reconsidered if allies refuse to contribute to what he has described as a “coalition of the willing” to secure the vital maritime route.
Tensions have escalated sharply around the Strait of Hormuz, a critical global oil transit point that has effectively been disrupted following US and Israeli strikes on Iran. The closure or instability of this waterway has raised significant concerns about global energy supplies and economic stability, increasing the urgency of reopening it.
Trump has been actively urging NATO naval forces to take part in securing the strait, but several European capitals, including key allies, have pushed back, maintaining that the conflict is not their responsibility. This divergence has exposed growing divisions within the alliance over strategic priorities and risk-sharing.
The reported threat has triggered intense diplomatic activity within NATO. Secretary-General Mark Rutte has been working to coordinate a unified response, reportedly advocating for a joint statement from major European powers such as France, Germany, and the United Kingdom to signal at least a degree of support for maintaining safe passage through the strait.
Trump’s stance reflects broader frustration with NATO, as he has repeatedly accused allies of failing to adequately support US-led initiatives while benefiting from American security commitments. He has publicly questioned the value of the alliance under current arrangements, arguing that the burden-sharing imbalance is unsustainable.
In parallel, Trump has also raised the possibility of reducing or even withdrawing US participation in NATO if allies do not align more closely with Washington’s strategic goals. His comments have added pressure on European governments, which now face a difficult choice between supporting US efforts in the Middle East or risking a weakening of transatlantic defence cooperation.
At the same time, Trump has continued to express confidence that the conflict with Iran could conclude relatively quickly, suggesting that US military actions have already significantly weakened Iran’s capabilities. He has indicated that operations could wind down within weeks, while also warning that the US could return with targeted strikes if necessary.
Overall, the situation underscores a complex intersection of military strategy, alliance politics, and global economic concerns. The dispute over the Strait of Hormuz has not only intensified tensions with Iran but also highlighted internal strains within NATO, raising questions about the future cohesion of the alliance and the balance of responsibilities among its members.
