No mere textbook could hope to “tell the full story” of Russian involvement in WW2. I can’t even imagine how one would tell the story without 5-6 simultaneous story lines going on.
Ivan had a rough go of it. A lot of that was Uncle Joe’s fault for stupidly firing/killing his officer corps so he started at a huge disadvantage.
Never a more treacherous bastard has existed than Uncle Joe in my opinion. I’m glad the Allies didn’t cave to his timeline and we kept our own.
I can understand how they may Poo-Poo our contribution, it’s not entirely without cause from their perspective.
Russia fought a hell of a fight, I’ll always give them credit for that.
