Have you notice that every time the Arabs want to show how much land the Palestinians lost due to the UN resolution setting up the state of Israel they always start out in 1946 with a green map. To correctly understand the problem, you should go back to 946 BC, not 1946. Even earlier, God promise this land to Abraham. See now there is no loss of Palestinian land. It was never theirs. God gave Israel this land plus much more, including all of Jordan, Lebanon and most of Syria. A large part of Iraq, Saudi Arabia and some of Egypt.
