Throughout most of World War 2, the United States and Britain were fighting ten German Divisions combined. The Soviets were fighting 200.
The United States lost about 300,000 people in combat, 400,000 overall, which was terrible but the Ruskies lost 27 million of their people.
There's a good reason Churchill says it was the Russians who tore the guts out of the German army, and Roosevelt recognized that, and Americans at the time recognized it which is partly why the Soviets were viewed so positively in the United States and by American people during World War 2.
Its part of the reason why there was a possibility for post-war friendship and collaboration as Henry Wallace and Roosevelt envisioned after the war and as Stalin desperately hoped for.
The whole Russian vision after the war was based upon this idea that the United States and the Soviets would remain allies.
That was essential for Stalin' political dreams aswell for his economical vision of how you rebuild the Soviet Economy, which was devastated.
Or the pressure of the soviets would have led them to surrender..
Aye, the Japanese armed forces was already crumbling there.
