This is an Anti-Zionist fraud. There was not much that the Zionists in EY could do. They had almost no money and were stymied by British and American obstructionism. In a few cases they were able to smuggle fighters into Europe and they did manage to save some Jews. There were even Zionist spies disguised as SS men (they had grown up in Germany and Austria and thus spoken fluent German).
As for the Nazi attitude, Himmler’s letter to the Mufti has recently been uncovered. You can see it on-line.
