Where is the line between "objectively assessing an enemy's weaknesses" and "blatant wishfull thinking" ?
While we're discussing how bad the russian air force is doing, cities are being bombed constantly, and the ukrainian governement is imploring for a no-fly zone that no one will enforce given it would mean engaging with, guess what, the air force. Oh, and starting a nuclear war at the same time.
Maybe it's an operationnal failure on Russian's side - but if so, they carved themselves a situation where they can't really _lose_, even if they can't win quickly.
Hopefully something will change the game - but I doubt "hoping for the other side to secretly be stupid" will cut it.
