Stalin’s grandson regularly “defends” his grandfather’s image.... btw,right now I’m reading “Stalin - the Red Tsar” — I strongly, STRONGLY recommend it. incredible book and a must read. It shows how the two evils of Naziism and Bolshevism seem to have fed off each other...
The bolsheviks were put into power by the Kaiser’s Germany, to include using German soldiers to fight against the White Russians.
The Weimar republic had German officers train in tank tactics in USSR. Hitler stopped that program, because he intended to have the tank training take place in Germany as he ignored the Versailles treaty.
Hitler and Stalin attacked Poland and Finland as allies.
Fortunately the Red Army’s relative incompetence in attacks on Finland, made Hitler drool. Churchill’s contacts with the Nazis in Portugal appeased Hitler, and rather than a hard fight with Britain over the sea lanes, he chose what he was sure would be an easier fight against Stalin.
