European NATO members should have been able to attack Iran instead of relying on the US and Israel, according to Secretary-General Mark Rutte, the head of the self-described defensive alliance.

Iran has been attacked twice in two years, both times over allegations that it seeks to develop nuclear weapons, which Tehran rejects as false. Speaking at the Euronews Defence & Space Summit on Friday, Rutte endorsed the idea that European nations should acquire the military capabilities needed to carry out such wars of aggression themselves.

In the future, “the Europeans will be able to take care of their backyard themselves. It should be us doing this, not the Americans,” he said.

“Europe was not able to take out the nuclear capability of Iran. We couldn’t. We didn’t have the capabilities. In 10 years, we can and we should,” he added, referring to multi-billion euro rearmament efforts now underway in European members of the military bloc.

Earlier in the day, the NATO chief dismissed Russian concerns over hostile rhetoric by some members of the bloc regarding the Russian exclave of Kaliningrad Region.

“Basically what we said is, ‘hey, listen, we are a defensive alliance, and stop the nuclear threat’,” he told journalists when asked about a formal warning Moscow had sent to Brussels.

Russia cited remarks by Polish Foreign Minister Radoslaw Sikorski, who proposed in September deploying additional troops near the Russian border so that Moscow would be “uncertain of what we will do.” Moscow said it would use its “entire available arsenal” to defend Russian territory from a possible attack by NATO states.

NATO was created in the early years of the Cold War, ensuring a continued US military presence in Western Europe. The Soviet Union later established its own military alliance, the Warsaw Pact, which no longer exists.

While NATO describes itself as a defensive alliance, it has carried out military attacks against other countries, including the UK- and French-led 2011 intervention in Libya, after which the North African state was balkanized.

Russia considers NATO’s eastward expansion since the end of the Cold War a major national security threat and has cited it as one of the principal causes of the Ukraine conflict.

Rutte’s argument in support of the US-Israeli attacks on Iran echoed remarks by German Chancellor Friedrich Merz, who said in June 2025 that the Israelis were doing “[the] dirty work for us.”
