You haven’t answered what else you think they should, or even could, do.

I think they should stop attacking other countries. It's really simple as that. It would be healthy to find some other ways to deal with unfriendly governments other than attacking them. Or just learn to accept that not everyone is aligned with you, as most do in similar situation. Though the idea that attacking and invading them is the only imaginable way is very on brand.

NATO is an organization of primarily imperial core countries, not really an international one.

International just means "existing, occurring, or carried on between nations." There's two or more different nations, it's inter national.
