Iran accuses NATO of ‘complicity’ in US war: What role did EU nations play?

What Happened

NATO Secretary General Mark Rutte disclosed that European allies provided logistical support during the US-Israel Operation Epic Fury against Iran, as part of an effort to ease transatlantic tensions after President Donald Trump criticized Italy, the UK, Germany, France, and Spain for insufficient support. Rutte said that 4,000–5,000 US aircraft took off from European bases over six weeks—500 from Italy alone—and Romania hosted tankers, while noting allies are now pre-positioning assets near the Strait of Hormuz for demining. UK allowed use of its Diego Garcia base only for defensive maneuvers; Spain and France refused airbase access.

Why It Matters

The disclosure of extensive European logistical involvement in a US-Israel war on Iran, despite public European reluctance and legal concerns, intensifies diplomatic friction between the US and its NATO allies over burden-sharing and the war's legitimacy. It provides Iran with a platform to accuse NATO states of violating international law and potentially opens avenues for Iranian reprisals or legal challenges, while complicating ongoing nuclear diplomacy and security in the Strait of Hormuz.

Watch For

Future Iranian diplomatic or legal moves against NATO members for complicity; responses from European governments, especially Italy and Romania, to clarify or restrict base usage; developments in the Strait of Hormuz demining operations and potential escalations; IAEA reports assessing Iran's nuclear status in the wake of the conflict; and domestic debates in European parliaments over participation.
