The Palestinians should not object, since creating "facts of the ground" that make repartition impossible will simply undo the UN partition decision of 1947 and make a Palestinian majority in the entire land inevitable in the near future. Denying equal civil and poltical rights to the majority of the population won't work in Israel/Palestine in the long run any more than it worked in South Africa. As far as the fantasy of expelling the Palestinians is concerned, just remember that Israel will lose all American economic, military and diplomatic support if it ever attempts to do that. If you believe that Israel can survive without that, you are entitled to your illusions, but don't expect them to have any relationship to reality.
