The international statute that says they CAN RETURN in the circumstances will do. It is a legal minefield if UNSCR 242 had meant for Arabs to be repatriated they would have said repatriated and solved it with one sentence,they did not for obvious reasons. Why are you waffling about compensation for the confiscated property of 850,000 Jews? Taking citizenship has nothing to do with it? Being born Jewish means nothing in and of itself. It is used as figleaf by ideologically driven Israel haters. PS Why do you keep ignoring Arab apartheid and its role in all this?
