Leaked Pentagon Email Suggests Suspending Spain from NATO Over Iran War Stance

A leaked internal Pentagon email, cited by Reuters, has proposed measures to punish NATO allies that Washington deemed insufficiently supportive of the United States-led military campaign against Iran, including the possible suspension of Spain's participation in the alliance, triggering swift denials and expressions of solidarity from European governments on Friday. The email, described by a US official to Reuters, specifically targeted Spain over its refusal to allow American forces to use two military installations on Spanish soil for operations against Iran. The document also proposed a review of the US position on the long-running sovereignty dispute over the Falkland Islands, a territory in the South Atlantic claimed by both the United Kingdom and Argentina. The disclosures prompted immediate responses from NATO, Spain, Germany, and Italy, all of which moved to reaffirm the alliance's cohesion and Spain's standing within it. The episode unfolded as European leaders gathered for an informal summit in Nicosia, Cyprus, providing a ready stage for allied governments to coordinate their public messaging.

NATO treaty offers no mechanism to expel members A NATO official, speaking to the BBC, stated plainly that the alliance's founding treaty contains no procedure for suspending or expelling member states, directly undercutting the premise of the Pentagon email's proposals. The North Atlantic Treaty, signed in 1949, was drafted without any expulsion or suspension mechanism, meaning any such move would lack a legal basis within the alliance's own framework. Spain refused to allow the United States to use the Rota Naval Base and the Morón Air Base, both American military installations located on Spanish territory, for strikes against Iran. Spanish Prime Minister Pedro Sánchez, addressing reporters at the start of the Cyprus summit, was direct in his response to the Reuters report. „Spain is a reliable partner within NATO and we fulfill our obligations to the Alliance. Therefore, no concern.” — Pedro Sánchez via NewsIT Sánchez also drew a clear distinction between unofficial leaks and formal policy, telling journalists that Spain does not shape its positions on the basis of internal emails but on official documents and positions expressed by the US government. „The position of the Spanish government is clear: absolute cooperation with our allies, but always within the framework of international legality.” — Pedro Sánchez via ΣΚΑΪ

Berlin and Rome step forward to defend Madrid's alliance role Germany and Italy moved quickly to publicly back Spain, with both governments emphasizing that the alliance must remain unified and that Spain's membership is not in question. A German government spokesperson, responding to questions at a regular press briefing in Berlin, was unequivocal in rejecting any notion that Spain's place in NATO could be challenged. „Spain is a NATO member state. And I see no reason why that should change.” — German government spokesperson via NEWS 24/7 Italian Prime Minister Giorgia Meloni, speaking from Nicosia where she was attending the same EU leaders' summit as Sánchez, framed the episode as a test of the alliance's fundamental value. „I believe that NATO must remain united. I think this is an asset that we possess.” — Giorgia Meloni via NewsIT The coordinated responses from Berlin and Rome reflected a broader European concern that Washington's frustration with allies over the Iran campaign could fracture the transatlantic relationship at a moment of heightened geopolitical tension. The British government, for its part, separately reiterated that its position on Falklands sovereignty remains unchanged, pushing back against the email's suggestion of a potential US policy shift on the disputed archipelago.

Iran war strains alliance ties as Hormuz shipping remains disrupted The diplomatic friction stems directly from the US-Israeli military campaign against Iran, which began in late February 2026 and subsequently disrupted commercial shipping through the Strait of Hormuz, one of the world's most critical maritime chokepoints. US President Donald Trump had repeatedly criticized NATO allies for what he characterized as insufficient support for the campaign, and the Pentagon email represented a more concrete expression of that frustration. British Prime Minister Keir Starmer stated that greater involvement in the war or in the American blockade of Iranian ports was not in the United Kingdom's interests, even as London acknowledged that it had allowed the US to use British bases for strikes against Iranian targets in the Strait of Hormuz and that Royal Air Force aircraft had participated in missions to intercept Iranian drones. The United Kingdom, France, and other European nations indicated they would be prepared to help keep the Strait of Hormuz open following a lasting ceasefire or the conclusion of the conflict. The episode illustrates the growing tension between Washington's expectations of allied solidarity in the Iran campaign and European governments' insistence on operating within the bounds of international law and their own domestic political constraints.

NATO was founded in 1949 with the signing of the North Atlantic Treaty, which established the principle of collective defense under Article 5. The alliance has grown from 12 original members to 32 states across Europe and North America. The treaty contains no provision for the suspension or expulsion of member states, a structural feature that has remained unchanged throughout the alliance's history. The United States operates two military installations in Spain: the Rota Naval Base and the Morón Air Base, both established under bilateral defense agreements. The Falkland Islands sovereignty dispute between the United Kingdom and Argentina has been a persistent diplomatic issue since at least the 1982 conflict over the archipelago.
