They were never on the same side. There were numerous treaties with Britain, France, etc that the Soviets proposed in order to take on the Nazis together, but they were denied, as western Europe and the US were doing a ton of business with Nazi Germany and were more opposed to the soviets. In fact, Western Europe already signed numerous non-aggression pacts with Nazi Germany, similar to the soviet-Nazi pact, but far earlier. The soviet pact was made on the eve of war to buy time, the soviets and Nazis never trusted each other.

This is only more clear if you look into how each country portrayed the other in the 30s. Communism and fascism are, again, polar opposites in property relations, they hated each other. The Nazis even saw Slavic peoples as being genetically inferior. Marxists were always opposed to fascism, and that didn't change when the Nazis came to power. They were never on the "same side," the soviets only went into Poland weeks after the Nazis did.

When it came time for World War II, all of that tension came to a head. The Nazis despised the communists above all else, and unlike Britain and France, tried to commit genocide against them. The communists despised the Nazis, and liberated Berlin years later.

All this statistics on manpower yet you're completely ignoring all of the shipments of food and materials the US sent to the USSR under lend-lease. The USSR would have starved and run even more extreme shortages on tanks and aircraft without US contributions.

I have read books om the Eastern front, from the Russian perspective. They tend to dismiss anything not Russian as a contribution to the war. That goes anywhere from claiming US materials did little tp saying that Ukrainians and Belarusians were incompetent, even though their soldiers, territory, qnd civilians bore the brunt of the fighting.

Let's also not forget that the reason the USSR was able to move their Siberian divisions to defend Moscow from Germany is because they found out that Japan wasn't planning on attacking the USSR - they were planning to attack Pearl Harbor instead. If Japan had decided to attack the USSR instead, they wouldn't have fresh winter-hardened troops to break the seige of Moscow, and would likely have to reroute divisions to reinforce a front line against the Japanese. And let's not forget that the US was the backbone (though not the only member of the allies) in the fight against the Japanese Navy.

Let's also not forget that a significant factor in the Germans advancing so quickly in Operation Barbarossa is because a lot of people in Ukraine hated the Russians because of the Holodomor. And the USSR didn't win any favors with Poles when they stabbed Poland in the back by partitioning it with Germany.

Reread my earlier comment. I never said the US won the war on it's own. I said the Allies won together, and that none of the members of the alliance could have won without the others.

But maybe that doesn't convince you. If not, I don't care.

I recommend you take your own advice. Pick up a book other than "Russia at War 1941-1945". Preferrably something that isn't full of anti-Ukrainian and anti-Belarusian propaganda.
