Good advice. Here's a scholarly, heavily footnoted (partial) history of Zionist complicity with Nazi Germany.
THE SECRET CONTACTS: ZIONISM AND NAZI GERMANY, 1933-1941 / KLAUS POLKEHN

Anti-Semitism became official German government policy when Hitler was named Chancellor of the German Reich on January 30, 1933. The spring of 1933 also witnessed the beginning of a period of private cooperation between Zionism and the German fascist regime to increase the inflow of German Jewish immigrants and capital to Palestine. The Zionist authorities succeeded in keeping this cooperation a secret for a long period, and only since the beginning of the 1960's have criticisms of it been expressed here and there. The Zionist reaction has usually consisted of declarations that their onetime contacts with Nazi Germany were undertaken solely to save the lives of Jews. But the contacts were all the more remarkable because they took place at a time when many Jews and Jewish organizations demanded a boycott of Nazi Germany.
To question the reaction of the Zionist movement to German fascism, which in the course of its twelve-year rule murdered millions of Jews, is a taboo in the eyes of the Zionist leaders. Only rarely is it possible to come across authentic evidence or documents concerning these occurrences. The following enquiry consists of information gathered up to this date about some important aspects of the cooperation between the Zionists and the fascists. It remains in the nature of things that this enquiry does not present a complete picture. This can only be possible when the archives (above all those in Israel), in which the documents concerning these events are under lock and key, are made available for scholarly research.
