This thread makes me glad that I left Russia to live in Australia. Never looked back.
Some of the points that have been brought up are somewhat valid and deserve to be discussed. Personally, I have played through the campaign and perceived it as a good attempt to cause an emotional reaction from the player. It was okay in that regard. There are movies and games where Soviets and Russians are so grotesque that it's laughable. COH2 is not one of them.
The tone, exaggerations and outright ignorance of the guys who try to convince the devs to put a disclaimer into the campaign intro are way out of line. The campaign is fiction, it is obvious to anyone with half a brain. In the end everyone will see what they want to see, no matter how many disclaimers are there.
