Ursula K. Le Guin’s The Dispossessed.
It always gets brought up as a book specifically about an anarchist society, but I think that’s mostly just because of the more negative connotations of the word “communist” and that most people don’t understand anarchism and communism share the same end goal.
It’s pretty hilarious how nearly everything you listed as if they’re contradictory points actually come together rather comprehensively to support the thesis that Russia is having to fight a belligerent NATO. And the one item that doesn’t fit wasn’t ever claimed by Russia to be a reason for the conflict.
I don’t know what anyone can do for you to cure your confusion when you can’t even connect the dots between the very things you are linking.
