Extermination of the Jews in German eyes had probably been the optimum solution of the Jewish Question from the beginning.
All other solutions took consideration of the geo-political reality as perceived at the time.
They all wanted to kill all the Jews but they hesitated to do so at once since they feared the consequences.
Hitler and his entourage decided to go ahead anyway thus giving the whole agglomeration what they wanted.
