There is information that supports the historical data of a relationship between the 3rd Reich and the Zionist movement in the 1930s. The two officially opposing groups worked a deal to allow German Jews to come to Palestine with their possessions.
In this way, the Zionists gained more people with professions to build the new country and the Germans were able to get rid of Jews from their country.
Hitler even had banks in Germany facilitate money transfers and even told the Gestapo to assist Jewish families to leave the country quickly and without harm. This is not in any "official" history books.
We even know that Hitler had many Jewish friends when he was younger and even had Jewish genetics.
