Adolf Hitler saw Zionism as confirmation of his belief that Jews were not Germans and were a separate nationality.
He wrote in Mein Kampf: "And whatever doubts I may still have nourished were finally dispelled by the attitude of a portion of the Jews themselves. Among them there was a great movement, quite extensive in Vienna, which came out sharply in confirmation of the national character of the Jews: this was the Zionists."
The same dynamic exists today as the grandchildren of Nazis support the Zionist genocide of Palestine.
