Actually about 2/3 of German Jews fled, but most couldn’t get out of Europe.
The Jews that left Europe were in a predicament. NO COUNTRY WOULD ACCEPT THEM. You remember that ship full of Jewish people that were sent back to Germany? No, the liberals in Germany along with the Jewish voters voted for Adolph Hitler. Most of the six million Jews that were put in the ovens or shopt were Jews from other countries that Germany conquered, along with the Jews in Germany.
