Pentagon Email Floats NATO Penalties for Spain Over Iran War Rift

A leaked Pentagon email has laid bare the extraordinary lengths the Trump administration is prepared to go to coerce NATO allies into supporting its controversial war against Iran, including considering the suspension of Spain from the alliance and revisiting long-standing US policy on Britain’s claim to the Falkland Islands.

The internal document, first reported by Reuters and circulating at senior levels of the Defense Department, expresses deep anger over what it describes as a European “sense of entitlement.” It complains that allies including Spain and the United Kingdom have been reluctant or outright refused to grant the United States access, basing, and overflight rights—described in the email as the “absolute baseline” expectation for NATO members during the conflict that began with American airstrikes on February 28.

The war has already triggered a major international crisis. Iran responded by closing the Strait of Hormuz, choking off a vital artery for global oil shipments and sending energy prices soaring. President Donald Trump has repeatedly lashed out at European capitals for failing to dispatch naval forces to help reopen the waterway, publicly wondering aloud whether the United States should simply abandon NATO altogether. “Wouldn’t you if you were me?” he asked Reuters in an April 1 interview.

The email stops short of recommending full US withdrawal from the alliance or the closure of American bases in Europe. But its menu of punitive options reveals a breathtaking willingness to weaponize NATO membership itself against dissenting partners. One proposal calls for suspending “difficult” countries from important or prestigious positions within the organization. Suspending Spain, the document notes, would carry heavy symbolic weight even if it had limited immediate military impact on US operations.

Spanish Prime Minister Pedro Sánchez, speaking Friday at an EU summit in Cyprus, pushed back firmly. “We are a reliable member of NATO that meets all its obligations,” he said. “We do not work with emails. We work with official documents and positions taken by the government of the US.” Sánchez reiterated Madrid’s stance: cooperation with allies, but only “within the framework of international legality.”

That careful phrasing underscores a central tension. Several European governments have grown uneasy with the legality and strategic wisdom of Washington’s war on Iran, a conflict that has already inflamed the Middle East and raised fresh questions about civilian casualties and long-term stability. The email’s frustration with ABO access suggests that some allies are quietly withholding full-spectrum support rather than sign up for what they view as an open-ended and escalatory American campaign.

A NATO official told Reuters that the alliance’s founding treaty contains no provision for suspending a member, casting doubt on the legality of such a move. Still, the very fact that the Pentagon is gaming out these scenarios signals how fractured the Western alliance has become. The United Kingdom, which has also drawn Washington’s ire, now finds itself facing the surreal prospect that the United States might reconsider its traditional support for British sovereignty over the Falklands—territory also claimed by Argentina—in retaliation for London’s insufficient enthusiasm for the Hormuz operation.

The episode comes as Trump continues to berate NATO partners for what he sees as chronic free-riding. Yet the leaked email suggests the administration’s anger has moved beyond rhetoric into concrete planning for intra-alliance punishment. Pentagon Press Secretary Kingsley Wilson declined to comment on the document’s authenticity when asked by Reuters.

This is not the first time the United States has tried to strong-arm allies during Middle East conflicts, but the explicit discussion of suspending a NATO member marks a new low in relations. For decades, American officials have portrayed NATO as a voluntary community of democracies bound by shared values. The email instead reveals a transactional view in which European governments are expected to fall in line behind US military objectives or face diplomatic and institutional isolation.

The timing is particularly damaging. With global shipping disrupted, energy markets volatile, and the risk of wider regional war still present, the public display of NATO infighting only underscores how isolated Washington has become in its decision to launch airstrikes on Iran. European publics and governments alike remain skeptical of another open-ended Middle East conflict launched without broad international consensus.

For Spain, a country that has contributed troops to previous NATO missions, the suggestion of suspension is especially galling. Sánchez’s government has tried to thread a needle—maintaining alliance solidarity while refusing to rubber-stamp actions it believes fall outside international law. That position now appears to have placed Madrid in the crosshairs of Pentagon planners looking for scapegoats.

Whether these punitive options ever move beyond an angry internal memo remains to be seen. But their existence alone will further erode trust between the United States and its closest allies. At a moment when global cooperation is desperately needed to manage the fallout from the Hormuz crisis and prevent further escalation with Iran, the Pentagon’s leaked retaliation menu instead highlights the growing willingness in Washington to treat traditional partners as adversaries when they refuse to fall into lockstep.

The email, obtained by Reuters from a US official speaking on condition of anonymity, makes clear that these ideas were not idle musings but options being actively considered at high levels. That fact alone ensures this episode will further damage America’s standing within the very alliance it claims to lead. As European leaders gather and try to manage the consequences of a war they did not ask for, the message from Washington appears to be less about collective defense and more about coerced compliance.
