While I'm sure Holocaust historiography has evolved over the last 50 years since it was published, the latter half of The Twisted Road to Auschwitz: Nazi Policy towards German Jews 1933-1939 covers how among other plans to set up Jewish colonies around the world, the Nazis did cultivate relationships with Zionist groups when trying to expel Jews from Germany.

The book makes a case that, to the Nazis, the Holocaust became a "final solution" when all the other "solutions" they tried for expeling the Jews from German public life before WW2 broke out had failed (eg, the aforementioned failed colonial projects).

I'd say that Evrala's comment has plenty of credible historical support.

When I say that the Nazi's turned on them, I'm saying that these select individuals that thought that working with the Nazi's would save them. It did not.

There were a few exceptions, there were some people that higher ups in the Nazi party helped to escape. For instance Adolf Eichman was proud of the fact that while many Nazis would point out a few "good ones" among the jews he was more pure in his belief.

The support for deporting Jews into Palestine was called the Haavara Agreement. 60,000 Jews were migrated to Palestine from 1933 to 1939. It was an agreement between the Zionist Federation of Germany and the Nazi government. The thought was that by working with the government they could make things easier on Jews still living in Germany.

Germany also got a lot of good international press for doing it at the time.
