At the age of six or seven, you also knew about concentration camps, bombs, who was Hitler, and so on. and etc? Somehow it seems to me not.

We knew, but I am good at 40. At that time, Hitler was not equated with Stalin, everyone knew that the Great Patriotic War was the Great Patriotic War, and the USSR won in it, and parents who survived the war childhood could tell their children about this and always raised a toast on holidays for "just if there was no war".
