NATO Secretary General Mark Rutte described the overnight US strike on Iran as 'absolutely necessary' during a joint appearance with US President Donald Trump at the NATO summit in Ankara, Turkey. Rutte said the operation weakened Iran’s nuclear and ballistic missile capabilities and called it a 'very strong response.' He emphasized that the strike was crucial for Israel, the region, Europe, and the wider world.

Trump declared that the existing ceasefire with Iran had ended following the attack, stating that the US had delivered a severe blow and would continue to respond to any Iranian aggression. After the US strike in southern Iran, Tehran launched retaliatory attacks, claiming to have targeted American military installations in the Gulf region.

Rutte also noted that under Trump’s pressure, European NATO members and Canada had agreed to significantly increase defense spending, though differences remained. Trump criticized some NATO members for insufficient support in the Iran operation, singling out Spain as a 'very bad partner' and instructing his treasury secretary to halt trade with the country.
