PS - My response was directly to your comment about "if Russia takes all of Ukraine they'd be right next to NATO, so why would they do that? (sic)"
Answer - having all of Ukraine as a Russia-controlled buffer is stronger to Russia than having Ukraine there now, not part of Russia - it would be a "buffer state" to NATO.
So I was answering your question.
PS - I find it almost comical that you have such an evil/good view of NATO (and the US) and Russia. ESPECIALLY since you think we have a fascist, maniacal, incompetent POTUS who can't be trusted.
