And Hitler was a dictator for life, not a socialist....
Hitler, as much as Lenin, Trotsky, and Stalin, was a scion of Karl Marx.
1. A year after Lenin's death, 1924, the NYTimes published a small article about a newly established party in Germany, the National Socialist Labor Party, which "...persists in believing that Lenin and Hitler can be compared or contrasted...Dr. Goebell's....assertion that Lenin was the greatest man second only to Hitler...and that the difference between communism and the Hitler faith was very slight...."
NYTimes, November 27, 1925.
2. Shortly thereafter the Nazis found it more useful to stress differences, and the earlier campaign posters showing similarities disappeared, posters with both the hammer and sickle and the swastika.
a. "Hitler often stated that he learned much from reading Marx, and
the whole of National Socialism is doctrinally based on Marxism."
George Watson, Historian, Cambridge.
b. "Socialists in Germany were national socialists, communists were international socialists."
Vladimir Bukovsky.
Your constant stream of inaccuracies and errors does serve a purpose....
...it gives me an idea for a future OP.
This one should compare Hitler and Stalin.
In terms of doctrine and methodology, it is hard to find a difference.
