Ok, I understand why I don't understand your point of view. We don't know the same history.
The USSR allied with the US, Europe, etc. during WWII, and if it weren't for the Soviet military and civilians fighting the fascist Nazis, Europe would not look like it does today.
Holocaust victims include socialists and communists. They were among the first sent to the concentration camps. Communism is an economic system that empowers workers instead of capitalists. So, when you say the victims of communism, do mean the capitalists who no longer hold all of the wealth?
It's bizarre that after WWII, NATO focused on our ally, the USSR instead of Germany and remained in Europe after the fall of the Soviet government. It also doesn't make sense that NATO bombed African nations that posed no threat to Europe and refused to negotiate with Russia prior to the war when its role is to defend European nations from the USSR.
Europeans did not want NATO to remain on the continent, and in the late 90s, the EU attempted to replace NATO. However, NATO bombed Yugoslavia while Europe sought a peaceful settlement, and refused to leave. Serbs hate NATO and the US to this day.
We don't know how every Russian feels, but as far as I know, NATO threatens Russians. No one wants missiles aimed at their country, and the US shouldn't decide what's best for Russians or any foreign citizens. That's not democratic, and keep in mind, we only hear one side of the story, and our government isn't a saint.
The Gulags weren't much different than today's US prison system - both are horrific. Stalin wasn't great, but he didn't control every aspect of the nation and he wasn't the only USSR president.
I've been to Auschwitz and a Japanese concentration camp in California. So, I find it odd that we scrutinize other leaders, yet we don't think about our government's brutal treatment of Americans and foreign citizens.
