the erasure of the Russian role in fighting the Nazis, as well as the troublesome views of leaders like Churchill I'm curious as to which of Churchill's views (or acts) you think were more problematic than Stalin's. And in the aftermath of WW2, which countries prospered more, those liberated by and/or occupied by the West, or by the Soviets?
