The nazis were NATIONAL socialists. They were not marxists. The nazis were not fascists either. Fascism is not national socialism. Nazism is a racist dictatorship, but fascism is a corporate dictatorship. Mussolini and Hitler did not see each other as ideological cousins.
On the other hand, Marxism is an anti-corporate ideology that promotes class warfare.
This subject, re: aforementioned posts, has been beaten into a pulp. There was nothing "National" about so called National Socialism. Mein Kempf itself demands expansion and the first thing Hitler did after gaining his power was to invade other nations, violate the treaty of versilles and expand internationally.
You must also note that the base of Nazism is, in fact, Communism. Hitler was a member of the German Communist Party before he was kicked out later entering the Thule Society where Nazism acquired its Blavatsky/Theosophy Germanic Paganist dogma. VIDEO:
Another good example of the similarities was the fact that Hitler gained much of his knowledge from the teachings of Lenin. For example to ascertain their similarites of both persona and ideological specificites compare the base quotes to which both Nazism and Communism are based: "A lie told often enough becomes the truth. " - Lenin; "The great masses of the people... will more easily fall victims to a great lie than to a small one." - Hitler.
Compare Germany's concentration camps, medical experimentations, forced labor etc. with the Gulag system. The two centralized power based systems are nearly identical with main exception being the injection of the Germanic/Nordic Paganism/Mythology.
The best book on this subject to date is by a Frenchmen named Jean-Michel Angebert - "
The Occult and the Third Reich: The Mystical Origins of Nazism and the Search for the Holy Grail". Combine that with Hannah Newman's work; "
The Rainbow Swastika":
