I don’t think it’s a matter for NATO per se. The US, however, is a different matter. They have a long history of piling into other countries’ wars, especially if Russia or China is involved. If not for the prospect of nuclear war I think the Americans would have counter-invaded Ukraine very early on. They may still do, but it wouldn’t be as NATO. Russia’s war would be with the USA, as no NATO member is under any obligation to become directly involved. America doesn’t give a toss about Ukraine, but it does about Russia, and that’s what this is all about. The irony is, Kennedy threatened the world with nuclear war over Soviet missiles in Cuba. Now they’re expanding their military empire right up to Russia’s borders, and wonder why the Russians don’t like it.
