I am by no means a Soviet apologist. I hate communism and all the regimes that attempted to implement it. That being said, there is an important distinction to be made between Nazi Germany and Soviet Russia: the average Russian had a shit life under the Soviet regime, reminiscent of life under the Czar, while the average German enjoyed many benefits in Nazi Germany.
A German in 1940 was most likely very happy with their situation, and didn't mind the fact that his nations armies were trampling upon the rights of every nation in Europe, while an entire ethnic group was being slowly disenfranchised. They are complicit because they benefited, and there's no getting around that.
Also, like I said before, it's idiotic to decry Soviet atrocities. Germany punched, the soviets just punched back harder. It's as if I punched you, then you punched me harder, and I accused you of war crimes.
And by the way June, posting pictures of dead bodies with a sarcastic message does not immediately invalidate my point.
