Spain's Prime Minister Pedro Sánchez condemns 'unilateral military action' by the US and Israel: analysis of impact and sovereignty

Tensions in the Middle East surged at the start of 2026. Amid air strikes by the United States and Israel against Iran, European voices opposed to the mainstream line grew louder. Spain’s Prime Minister Pedro Sánchez explicitly condemned what he described as ‘unilateral military action’ that he argued violates international law. Madrid’s move was more than rhetoric: Spain formally banned the use of joint military bases at Rota and Morón for those operations. The decision sparked a major shock within the NATO alliance and placed Madrid–Washington diplomatic relations at their lowest point in decades. In a statement on X on 28 February 2026, PM Sánchez asserted that the world could no longer bear ‘another devastating war’. Three fundamental reasons underpin Spain’s hard line. This stance did not pass unnoticed in Washington, where US President Donald Trump threatened to cut trade routes with Spain, calling the decision a form of ‘betrayal’ within the defence alliance. Although pressured economically, the Spanish government remained steadfast. Foreign Minister José Manuel Albares stated that national sovereignty cannot be negotiated. The move reflects a shift in European thinking, with several countries beginning to question the direction of US foreign policy, perceived as overly aggressive. Since the Gaza conflict erupted in 2023, Spain, under Socialist leadership, has positioned itself as a defender of civil rights and Palestinian sovereignty. For Sánchez, consistency in upholding international humanitarian law is key to Spain’s diplomatic credibility on the world stage. Militarily, this is straining NATO operational coordination on the southern flank. Economically, Spain risks facing high trade tariffs or sanctions from the United States, one of its major trading partners outside the European Union. Sánchez’s willingness to condemn unilateral military action marks a new chapter in European geopolitics, with Madrid positioning itself as a moral voice that prioritises peaceful coexistence over blind military alliances. In the 2026 global political landscape, Sánchez’s statement drew renewed international attention. Diplomatic ties between Madrid and Washington reached their lowest point in March 2026.
