Adolf would have done anything to have the Jews leave Germany. The Nazis in general toyed with different ideas in the 1930's. See for example the Madagascar plan. https://en.wikipedia.org/wiki/Madagascar_Plan
. It is also true that this rhetoric inspired Zionist to make their case stronger for establishing an Israeli state in Palestine. of course, the problem was that nobody wanted to have the German Jews come to their country. There were also problems with the British Mandate in Palestine since the Arabs were already protesting to the mass migration of Jewish settlers there. This meant that the British were following a policy of a compromise in order not to upset the Arabs in their colonies but also not to upset the Jews in England and abroad. In any case, under these conditions it was simply impossible for the Nazis to implement any plan of an effectively forceful relocation of the German Jews and gradually the solution came in the form of exterminating them.
