According to individuals with direct knowledge of high-level discussions, former US President Donald Trump threatened to cease supplying weapons to Ukraine in an effort to compel European nations to join a proposed 'coalition of the willing' aimed at reopening the strategically vital Strait of Hormuz. This critical maritime passage has been effectively closed by the Islamic Republic since the onset of recent regional hostilities, blocking a route responsible for transporting approximately one-fifth of the world's daily oil and liquefied natural gas supplies.
European Resistance and Presidential Pressure
Last month, President Trump publicly called upon NATO member states to assist in securing the narrow strait, but his appeal was met with firm resistance from European capitals. Several governments explicitly stated that such an operation would be impossible while active combat continued, with multiple officials declaring the conflict was 'not our war.' In a retaliatory move detailed by the Financial Times, Trump threatened to withdraw support from NATO's Purl initiative, a European-funded program that facilitates the procurement of American weaponry for Kyiv's defensive war effort.
Hastily Assembled Diplomatic Response
The US President's stark warning prompted urgent diplomatic activity. At the urging of NATO Secretary-General Mark Rutte, a coalition including France, Germany, and the United Kingdom issued a joint statement on March 19 expressing their 'readiness to contribute to appropriate efforts to ensure safe passage through the Strait [of Hormuz].' An official familiar with the President's strategy told the Financial Times that Rutte insisted on the statement specifically because Trump had threatened to exit both the Purl program and broader Ukrainian support.
'The statement was then quickly assembled under considerable time pressure,' the source explained, noting that additional nations signed on afterward as there was insufficient opportunity to coordinate all potential signatories initially. In the forty-eight hours preceding the statement's publication, Secretary-General Rutte participated in multiple calls with President Trump and US Secretary of State Marco Rubio to manage the escalating crisis.
Behind-the-Scenes Tensions and Accusations
One official disclosed that during a call with French, German, and British counterparts, Rutte characterized Trump as 'rather hysterical' over the allies' refusal to assist in securing the Strait of Hormuz. British officials, while not explicitly denying Washington's threat to withdraw from Purl, confirmed that the UK and US were engaged in military-level discussions regarding options for protecting the strait prior to March 19.
Deputy White House Press Secretary Anna Kelly reinforced the administration's position, stating, 'President Trump has made his disappointment with NATO and other allies clear, and as the president emphasised, "the United States will remember."' In a recent interview with The Telegraph, Trump labeled the alliance a 'paper tiger' and declared that removing America from the foundational defense treaty was now 'beyond reconsideration.'
Escalating Rhetoric and Alliance Reevaluation
In recent weeks, the President has intensified his criticism, accusing European allies of being 'cowards' who have contributed 'absolutely nothing' to the conflict with Iran. He emphatically declared, 'The U.S.A. needs nothing from NATO, but "never forget" this very important point in time!' Secretary of State Marco Rubio echoed this sentiment during a Fox News appearance, indicating that America would 'reexamine' its relationship with NATO following the conclusion of the Iran conflict.
'I think there's no doubt, unfortunately, after this conflict is concluded, we are going to have to reexamine that relationship. We're going to have to reexamine the value of NATO in that alliance for our country,' Rubio stated, clarifying that any ultimate decision would rest with President Trump. The President previously informed Reuters that he planned to announce in a Wednesday evening address to the nation that he would 'absolutely' consider withdrawing from the Western alliance.
Ongoing Developments and Military Implications
When questioned about Trump's frustration regarding European positions on the Strait of Hormuz, Secretary-General Rutte responded, 'I am confident that allies, as always, will do everything in support of our shared interests.' During his televised evening address, the President doubled down on his demands, urging nations struggling with fuel shortages to 'build up some delayed courage, go to the Strait and just take it. Protect it.'
Since the March 19 statement's publication, additional nations have added their signatures. The United Kingdom is scheduled to host talks on Thursday involving thirty-five countries, aiming to form a coalition to reopen the crucial waterway 'after the fighting has stopped,' following weeks of sustained pressure from the Trump administration.
Weaponry Demands and Supply Chain Concerns
The intensified US-Israeli military campaign against Iran has significantly increased global demand for Pac-3 interceptor missiles, which are fired by Patriot air defense systems. These interceptors are utilized by Gulf nations to defend against Iranian strikes and constitute a central component of Kyiv's defense against Russian missile attacks. Secretary Rubio confirmed on Friday that US military supplies to Ukraine via the Purl initiative have not yet been reduced due to the Middle East crisis, stating, 'Nothing yet has been diverted.'
However, Rubio did not rule out the possibility that Washington might, in the future, seek to redirect weapons originally earmarked for Kyiv to replenish American stockpiles depleted in the war against the Islamic Republic. 'If we need something for America and it’s American, we’re going to keep it for America first,' he asserted, highlighting the potential for ongoing tension between European security interests and US strategic priorities.
