Before the Nazis initiated the Jewish genocide, they considered deporting the Jews to Madagascar. This plan was abandoned because of Britain's ongoing resistance. However, let us assume the British make peace in 1940 for whatever reason. Maybe Lord Halifax becomes Prime Minister instead of Churchill, or the BEF is captured at Dunkirk. How Britain makes peace is irrelevant. Anyway, the result of this is that the Germans now have access to the sealanes and decide to institute the Madagascar Plan. What would have been the consequences of this?
