The expulsion of Jewish minorities from other countries was criminal, and should obviously be reversed. However in very large part this happened in the wake of the expulsion of the majority Palestinian population of what became Israel. Without that precipitating factor there is no reason to believe it would have happened.

Any right of return for Palestinians should be accompanied by a similar right of return for Jews who see living in Israel as exile from other countries. So far as I know this demand has never been put on the table in negotiations, and it surely should be.
