Mats, I think that it goes without even saying that Arab people who were forced to leave and their descendants of course MUST be allowed to return. No ifs, and buts. And of course since they would most likely will want to live under Sharia laws they need to be given autonomy or sovereignty (which ever they would prefer). However, I don't think that Arab countries would ever except that deal because Jews would demand to be compensated for the wars of aggression started by Arabs with money, land and resources. And of course millions of Middle Eastern, North African, etc. Jews will present their counter demands for autonomy and/or sovereignty within Turkey, Libya, Egypt, Syria, Yemen ,etc.
