Could the Axis have won?

[Tsar Alexsandr]

“Really they are the same thing. A collectivist control scheme branded with a different name. So although they call themselves diehard enemies, they're not incompatible.”
To tell is not enough. Please develop.
They have similarities, but no, there are not the same. By the way, where is collectivism in Nazi Germany?
Nazism is based on racism, not on political choices. They are enemies. One thinks there are races of Lords and Slaves, the other believes in equality. It is not because water and fire can destroy a lot that they are the same. Both are natural disaster, but there finishes the comparison.
To go with your way of thinking, Communism is the same than Christianism. They both slaughtered a lot of people for their own good, and to help them to understand the true and to build happiness…

Well the basics of a collectivist system is the belief in the good of the many outweighing the good of the individual. And therein lies the purported goals of Nazism and Communism. The Nazis did try to appeal to the working class. A blue-collar sort of regime. For the third Reich, the good of the many, Germans, did outweigh the good of the Germans who opposed the regime, the disabled, and all the convenient minorities who were used as a scapegoat.

The Communists always appealed to the working class. It was "The People's Revolution." Just like how China is the People's republic. Once again, majority rules. But of course, this majority is represented by a very small elite minority. Just like the Nazis, only the Nazis could have even fewer truly powerful individuals.

Nazism and Communism are variants of Collectivism. But not Collectivism perfectly.
