The EU Commission formally backed Spain after President Trump directed Treasury Secretary Scott Bessent to "cut off all dealings with Spain" — retaliation for Prime Minister Sánchez's refusal to grant US forces base access for offensive operations against Iran. The European Council president expressed "full solidarity" with Madrid. EU-US trade deal ratification is now frozen in the European Parliament, compounded by a court ruling that invalidated Trump's global tariffs.
Madrid's position is more nuanced than simple opposition. Spain deployed the air defence frigate SPS Cristóbal Colón (F-105) and replenishment ship SPS Cantabria (A15) to Cyprus — separating its objection to this specific war from its standing NATO and EU defence obligations. Tehran praised the refusal, an endorsement that complicates Spain's diplomatic position without changing it.
Trump's economic threat against a NATO ally prompted the collective European response Brussels has struggled to produce on other transatlantic disputes. But the solidarity has clear limits. France authorised US use of its bases and deployed Rafale jets to the UAE. Germany is weighing direct combat entry. Europe agrees on Spain's right to refuse; it does not agree on whether the war warrants European participation.
The precedent is the operative concern for European capitals. Economic coercion of allies who decline to join a military campaign that lacks UN Security Council authorisation — Russia and China would veto any resolution — raises a question every NATO member now faces: whether alliance obligations extend to wars of choice, and what Washington will impose on those who answer no. Spain is NATO's sixth-largest military contributor. The answer matters beyond this war.
