But there is no spin. There's either global thermonuclear war or there's nothing. If NATO isn't invading Russia, and Russia isn't invading NATO, then nothing has changed.
Does Russia want to start global thermonuclear war because they can argue a technicality that it's not their fault? No, I don't think so. They could start the war and the outcome would be the same at any time they want.
Excusing the edge case of a pathetic attempt of a land invasion of Finland or Poland or something crazy.
He's also very very scared to do anything of consequence. Look, the Ukrainian invasion was the only reckless thing he's ever done and look how it turned out.
If the US sends a merchant ship and a cruiser, what is russia going to do exactly? Try to bomb the ships? They will lose, and get shot down.
Why would it suddenly be WWIII? Is russia really going to say "Well, they shot down our plane so its global thermonuclear war time".
