I've been reading about WWII, specifically about the buildup to D Day and the interactions between Churchill, Roosevelt, and Stalin. Through it all Stalin keeps complaining about how he is doing the bulk of the fighting, and Churchill and Roosevelt are very concerned with drawing Axis units away from Russia.
Strategically this makes sense as the situation is much better if there are two fronts than one, but at the same time Stalin played a large role in letting Hitler run rampant. Did everyone essentially put up with Stalin because they had to, or were there instances of people at the very least call in him out on siding with Hitler in the first place?
I'm not aware of any instances where the allies tried to call out Stalin. However it would have been very hypocritical of them to do so given the fact that they too made a deal by giving Hitler Czechoslovakia. Secondly, Stalin first wanted to make an anti-Hitler military alliance with France and UK but was essentially rejected. The infamous Molotov-Ribbentrop Pact was not what the Soviet Union wanted but rather forced into as the least bad option.
