Prior to the Holocaust, there was a significant part of the Zionist movement that was playing footsie with the actual Nazis. The Nazis didn’t want to kill the Jews, they wanted them out of Europe. Zionists thought that made them potential allies. Ultimately, that didn’t work out because the Nazi’s thought that moving them to where modern Israel is would be too destabilizing for the region. The Nazis still ended up supporting establishing a Jewish state, with Hitler approving a plan to do so in Madagascar. This plan was eventually abandoned in favor of their “final solution”.
