From a documentary I watched some time ago, the original plan was to just move these Jews, Gypsies etc. out of Germany to places like Poland. Then it was realized that it wasn't a good idea having an increasing number of hostile people right next door to you. Then the idea came about of transporting them to Palestine but the Arabs wouldn't agree to that. When that possibility was exhausted the "final solution" was arrived at...extermination in the death camps. Just wonder what other alternatives could have been pursued?
