Well - one mans propaganda is another mans truth!
Where I lived, we heard both sides of this story, presented in a relatively unbiased way.
But I agree with it-ogo: Media from the socialist countries were always on about "friendship", "solidarity", "brotherhood" and Peace etc, etc..
Whereas the US films were always picturing Russians as bad people.
And then now - Russians always have extreme roles in films: Gangsters of some kind or another, for example.
