It is worth recalling this key line from the Protocol:
It raises two questions. Firstly, why would it be safer "in wartime" to send Jews to the East, where the military conflict was at its most intense and insecure position, than to let them go to a country such as Morocco or Palestine, to which Germany had no objections to letting them go in 1939-40? Secondly, what are the "possibilities in the East"? Most western Jews were unsuitable for labor over there and would be a rapidly diminished labour force. The unfit Jews would gradually starve if not simply killed on arrival. Costs of maintaining camp security would be prohibitive, and there would be a constant risk of prisoners escaping to the partisans. Heydrich and Eichmann must logically therefore be referring here to the possibilities of killing these Jews, just as Soviet Jews had been killed in large numbers in the preceding months.In the meantime the Reichsfuehrer-SS and Chief of the German Police had prohibited emigration of Jews due to the dangers of an emigration in wartime and due to the possibilities of the East.
