Spanish Prime Minister Pedro Sánchez has described the joint US and Israeli attacks on Iran as the beginning of a 'catastrophe for humanity.' Speaking on March 4, 2026, Sánchez made clear that Spain does not support war and that the Spanish people stand against what he called a growing disaster. He strongly criticized the military actions and reaffirmed his country's stance for peace.

Sánchez recalled that the 2003 invasion of Iraq had made the world less safe and argued that a new war against Iran would not lead to a fairer international order, a healthier environment, or better lives for ordinary people. His comments came as tensions escalated following the attacks in Iran and the broader regional fallout.

In response to Spain’s refusal to allow US forces to use its bases for the Iran operation, former US President Donald Trump threatened to cut all trade ties with Spain, further straining diplomatic relations between the two nations.
