A map has nothing to do with it. If you own ten houses, do I have a right to take 1 to give it to a homeless family just because you have ten. That is a very weak argument. Nonsensical in fact. Here the Jews were given 1 house, but they were not satisfied with the gift and then stole more gifts from under the Xmas tree. Regards.
