Why did Hitler hate the Jews? That he was a madman is insufficient. That explains nothing. That he had a hatred that began to blossom with the expulsion of the Jews from Germany to full bloom with the Final Solution is without parallel unless one compares Hitler to Moses. I once tried to point out Hitler's association with the officers when he was a messenger. The memory of such conversations by the officers, when the Balfour Declaration was published, led Hitler to recognize Zionism as an enemy of Germany. He conferred nationhood to the Jews and sought to expel them. The rest is history.
