I think Hitler wrote it because Zionist ideology was very much like NS ideology in that marrying outside race and ethnicity was frowned upon and they both wanted their own ethnic state. Many Zionists worked for thr NS, and the one of the founders of Mossad was formally a National Socialist. Hitler's Jewish past and his associations with Kabbalist occultists Jews who taught him how to speak effectively in front of the public certainly make it clear that he was at the very least using Zionism for his own agenda. That is clear.

There was much treachery in Hitler's Germany. That treachery would certainly be unconstitutional here. The eugenics implemented by the Nazis was disgusting, however, I'm not docking Hitler's social programs or many of the things he did say which I agree with. But anyone can agree with certain things someone says, no matter the person.
