NATO Secretary General Mark Rutte noted that alliance member countries support the US operation against Iran, but the details of applying Article 5 of the collective defense will remain under a very tightly guarded veil. He said these words on March 4 during an interview with Newsmax.

For good reason we will always remain deliberately vague about when Article 5 of the treaty triggers, which states that an attack on one member is considered an attack on all… We keep this ambiguity because we do not want our enemies, our adversaries, to learn more about it… We can and will defend every inch of NATO territory

The Secretary General clarified: in the event of the invocation of Article 5, the alliance will immediately outline its steps, but for now there remains a degree of ambiguity to deter adversaries from taking risky actions against NATO’s security.

Rutte emphasized that NATO formally is not participating in the operation against Iran, but inside the alliance there is “wide support” for the U.S. president’s campaign to destroy Iran’s nuclear and missile capabilities, even despite criticism from some European leaders.

NATO is not participating. But clearly, allies, in essence, are broadly supporting what the president is doing, and also contributing to what the United States is currently doing in the region by destroying Iran’s nuclear potential and, of course, the missile potential
