Germany lost its entire army in Operation Bagration which was inside the USSR. They didn't lose on the outskirts of Germany.
If Russia lost its army in Ukraine then they can pull a reverse invasion into Moscow. Clearly that hasn't happened otherwise they don't need to release proven fake photos and make verbal claims, they'll just release real photos.
You think just because your definition of winning by Ukraine (in this case IMO winning is by not losing with the invasion) is by wiping out Russia's military forces, and that they should start an operation against Russia that hasn't been seen since WW2, by taking over Moscow is a true victory.
