Communists and Nazis were two rabid dogs fighting over the same bone.
Ironically, you could say Stalin also was a “National Socialist”, as he rejected Lenin and Trotsky’s Internationalism” for “Socialism in One Country”.
He also was, despite being Georgian, a Russian supremacist, favoring ethnic Russians, and forcing other ethnicities to abandon lands where they had lived for centuries in favor of ethnic Russians, and also depending Russian be the first language of all Soviet citizens.
NAZI = National Socialist German Workers’ Party
Stalin was not a native Georgian. He was an ethnic Russian brought up in an exclusively Russian community in occupied Georgia. He hated Georgians right from his childhood.
