The invasion was never about suppressing fascism. Russia is as bad an actor as the United States has been generally, worse realistically. (Annexing many many countries at gunpoint post world war II. Slaughtering many in gulags for simple dissent. Invading, Afghanistan etc etc etc etc etc etc etc. ) Neither one is good. And we should not be justifying either one.
In this one situation, however. While the United States isn't strictly the good guy. They are more in the right than Russia is.
