Ah, that is quite interesting… I didnt know about this. However, you should note that it was a recurring idea by many countries (whether Madagascar, or some other region), due to the Jewish diaspora which was culturally incongruent.

The nazis were instead fanatical, and aside from directly targeting jews with extreme hate, attacks, the “final solution” was drawn up and relentlessly pursued throughout the war. I havent read up whether its idea origins are somewhere in 1935-1939, but I would assume so.
