Except The Nazi party didn’t have eighty percent of Jews promising to vote for it no matter what.
There were, however significant numbers of influential Jews, nationalistic ones who had served in WWI (Iron Cross, brave German Jews) who then served in the Freikorps and Berlin police and elsewhere in the country. These people believed in what was to happen for nationalistic reasons— and only later realized (much too late) what was in store for them.
One could almost believe this today, if somehow the dems could contrive to make being a liberal a nationalistic patriotic move (like getting us into a war— like FDR did). This is how it’s done. Appalling really.
