The USSR killed 80-ish percent of the nazi troops, and suffered 26 million casualties, mostly civilians exterminated by the nazis. They were mainly responsible for the victory and suffered the heaviest losses, including a lot of the lower level communist organization whose absence lead to the bureaucratic centralization (that Stalin opposed heavily before his death) that let corruption gradually take over the project.
Yeah, when you organize your army based on politics and not on, you know, military capability, you end up sucking at war and need to make it up in numbers. You ignore intelligence of imminent invasion you let hundreds of thousands of troops get encircled and begging the Yankees for resources.
So, no argument at all? Just a downvote and an ad-hominem? I’m disappointed…
