Iosif Stalin - on the notion of a superior race

Iosif Stalin, the General Secretary of the Communist Party of the Soviet Union, rebuking Nazism's claims of superior and inferior races existing, in particular on Nazi claims of Slavs (including the many Slavs of the Soviet Union) being inferior to Germans as being more Nordic  than Slavs were in terms of the Nordic racial subtype of the Aryan race than Slavs that Nazis viewed as the purest and most superior manifestation of the Aryan race and that multiple civilizations flourished because of an elite with significant Nordic Aryan racial heritage even if the commoners of the society were largely non-Nordic. Stalin notes that the Romans used to think they were a civilized superior race and regarded Germans as barbaric inferior race and how it was German tribes who led to the destruction of the Roman Empire. He perceives that just as Rome fell from being a major power from war with the Germans in spite of its sureness of superiority over them, that so could Germany fall should it dare to confront the Soviet Union if it did not learn this lesson from history.
