What exactly was the reason behind the allies establishing Israel, after the war in 1948? I have seen some articles about how originally, they planned a Jewish state in Madagascar. I would think that Jews having their own state, would put them in more danger, as outside forces could try to push them out like in the multiple Arab Coalition wars, and start a 2nd holocaust.

Why was it so important to give the Jewish people a state, even though the Nazi's were defeated?
