Yes, I was going to quote the Jordanian experience. The palestinians were expelled becasue they were destabilizing Jordanian politics with demands for a perpetual military conflict with Israel; something that was not in Jordan's interest, politically or economically.

So finally they accepted that if the palestinians refused to assimilate and become Jordanian, instead continuing to agitate over their own foreign concerns, then they couldn't be in Jordan.
