The US is an empire. So was the USSR. So are China and modern Russia. Some provinces are treated better than others, but empires are empires, and propaganda, political manipulation, corruption, violence, and torture are how they roll - together with resource capture, labour management, and various levels of market development.
Europe had a notable level of propaganda and political manipulation, and still does, and not so much of the overt violence. But just because the corruption, violence and torture were happening elsewhere doesn't mean they weren't happening at all.
I guess I should thank the SU for stealing our uran, making my fellow citizens forcibly work in the mines as a punishment for not being communist enough, and for hindering our economical development by decades (of the country that used to be one of the most advanced European states before the war, and got destroyed AFTER the war so much that it fell below Africa in HDI)? Well, thanks...
I think you don't even need the hindsight, just look at history: Soviet Union and Nazi Germany started the war as allies, their first action was splitting Poland... why would anyone expect they would have stopped there?
So, essentially, we are supposed to thank Russians for liberating us from their former allies (and even that only happened because their former allies stabbed them in the back first). I don't know... after the Nazis attacked the Soviet Union, what options had Soviet Union left other than fighting back?
If you become friends with the Nazis, start a war together as allies, then you get betrayed by them, then you defend yourself successfully (with help of many other countries) and finally defeat them... that doesn't really make you a textbook example of a good guy. You need a lot of propaganda to make people forget how this all started.
