The only salient fact is that people, in this case Palestinians, owned, had legal title, to property. That the overlaying government changes doesn't change that fact. Those Palestinians had their property stolen from them and they were driven out. It is that uncompensated theft and ethnic cleansing, that is at the heart of the problem and it will continue until either the Palestinians are eliminated, as Israel is apparently trying to do, or the Palestinians are made whole.
