Because Zionists loved Hitler. Not because he was one of them. They respected him for the Transfer Agreement which started the migration of German Jews to Palestine. It was the biggest step in creating Israel since the Balfour declaration of WW1. Without Hitler and the six million prophecy fulfilled from their books, the Jews could not have their homeland of Israel.

Hitler didnt want them in Germany anymore like the dozens more countries before Germany, so he helped them get a homeland.
