Even if, especially if, Putin was a closet commie Soviet then it would make sense to back off. I wasn't a big fan of MAD, but it does seem to have kept us from nuclear destruction.
We didn't help Hungary during their uprising. We didn't help the Czechs after the Prague Spring was crushed. In both cases I believe it was because we didn't want the Cold War to turn Hot. Why would we believe that what we're doing in Ukraine isn't going to result in much of the Earth getting extremely hot?
There are.
Nevertheless, it's easy to recognize that as far mas the governments are concerned, there are no good guys in this fight. Being of Ukrainian heritage does not cloud common sense judgment and make someone by default a Zelensky supporter.
My heart goes out to all the average citizens who are caught in the midst of this conflict. I have no doubt, the majority of them just want to go to work, raise a family, and live in peace.
