I do NOT agree that the Nazi movement was closely affiliated with communist political philosophy. It was nationalist, authoritarian, driven by resentment from WWI humiliation, however.
Stalin had nothing to do with Hitler coming to power.
“I do NOT agree that the Nazi movement was closely affiliated with communist political philosophy”
The differences are too trivial to worry about. They both called themselves Socialist. Both had widespread use of mass murder, suppressed and murdered intellectuals, had widespread rooting out of political heretics, worshipped and swore allegiance to one infallible heroic “dear leader”. had an aggressive foreign policy, etc.
The differences between Nazi Germany and Soviet Russia are no different really that the differences between any two communist countries.
Consider...
A Vietnamese communist VC might tell you he is Buddhist and that Ho is just a nationalist. A North Korean communist might tell you Kim IS God and that business is evil. A Chinese communist wants to sell you Iphones and banking services and doesn’t care about religion as long as its not Fallon Gong that hates the state. Pol Pot says everyone with glasses who can add numbers must be killed, and that everyone must be Agrarian in year zero. Central American communists claim to be good Catholics and that they follow Liberation Theology.
A Soviet communist is also a Russian nationalist, and is different by era. A Russian from 1920s would have been horrified by a Russian of the 70s and 80s. And a Russian communist from the 70s and 80s mostly looked at the Stalin era as a big nightmarish mistake, (but would NEVER admit that to an outsider.)
The point is that almost every communist nation is drastically different in many deep order fundamental ways. Castro privately scoffs at the belief that Kim is a God born without an a$$hole.
So the differences between a German Nazi and a soviet are no greater than can be found between any other two random communist nations. Its fair to call a Nazi a type of communist, and it has the added benefit of annoying them.
A final thought, a stunning number of early Nazis and brownshirts were communist street brawlers at first. They didn’t become Nazis because their philosophy changed, they simply moved to what they saw as a winning team.
Stalin’s little buttboy (you posted the wiki-link up there) was clearly the right choice for that dictator, but accomplished nothing but pissing off everyone, turning coat, backstabbing, and pushing for an authoritarian, nationalist, hegemonic communist dictator. So, no, there’s no difference.
