Stalin only lived 8 years longer than Hitler. Why do you think that there are "literally millions still alive from his time" but the few remaining people that suffered from Hitler would be dead or ancient?
I was speaking of Stalin-ism that was still in effect up until the 80's but little changed from his time in power and still killing and enacting by policies set during his life. I thought that would be quite obvious since I kept referring to the regime of Hitler instead of calling it the Reich.
