There’s a lot of layers to this. Among them the problem that yanks and other westerners with an exceptionalist world outlook have been convinced that only the good guys win, and that to win means to be the good guy no matter how abhorrent they are. So to accept that Russia is winning or, at least, that Ukraine can’t win, means accepting that Russia is in fact the good guy. Which is clearly nonsense, but then neither you nor I are making the claim.
