Nadav, morality is a much softer matter than legality. If you have some clear cut rule, either in the Bible or the Gemara, I will accept it. Of course, the Arabs might have their own code of morality. In any event, people tend to stretch moral arguments beyond validity. You can do it by appealing to emotions or even by slightly changing the correct description of reality. At least in the field of international relations (in addition to driving), the goal is to resolve conflicts to further self interest: "Don't be right, be wise". As far as history, there were twice as many Arabs in Palestine in 1948 as there were Jews. They no doubt expected to win on their own. If you read about the War of Independence, you will find that for the first 4 months the Jewish situation was very difficult. Only beginning in April 1948 did the tide turn. The Pals had a chance even without the invasion. In any case, there are 2 factors that put some obligation on Israel to deal with the refugees: 1. They left behind much property, now in Israeli hands. "Thus saith the LORD, Hast thou" expelled, "and also taken possession?" - 1 Kings 21:19 2. Many of the refugees were actually expelled unnecessarily. It was local initiative, but done on a significant scale. This is not the Arabs fault, but Israel's.
