I know many Jews who were born in various Muslim countries, Lebanon, Palestine (they're in their sixties and seventies), Egypt, Iraq, and Turkey. Jews largely flourished in pre-Khomeini Iran. Some would really like to return someday, although they know they won't.

My imnpression is that making it possible for such people and their children to do so, and seeking to reestablish the historic Jewish communities in such countries is not seen by the Israeli authoriries as either a priority, or even as desirable. It seems quite possible that putting it on the table as a negotiating goal might be a very positive step.
