The claim is that it would be a global fuck up, maybe implying that it wouldn’t be limited to Russia/nato. Not that this wouldn’t be messy in and of itself, if Russia were to invade, I suspect they would be left out on their own by everyone else. They’re already struggling with Ukraine. I doubt anyone is going to want to step up and help them against NATO. They would probably lose a lot of the external but indirect support they are getting right now because countries would be hesitant to support a country against the us.

If it’s just “war is bad” then yeah, kind of a duh statement.
