They'll be wiped out because there is no advantage to the Israelis in keeping them around. As soon as the Promised Land ceases to be Palestine, the sooner people will stop trying to give it back to the Palestinians. And the Palestinians are out-gunned, out-classed, out-flanked, out-numbered, out-maneuvered and outdone. When your burliest weapons are Katyusha rockets (basically a giant, dumb bottle rocket) and explosive vests and you're up against a numerically superior force that can literally design a new kind of tank that's half bulldozer to run over your villages (although this is actually a Merkava minesweeper but still - c'mon)
Well, you're fucked. The Palestinians are a pawn of the greater middle east. Every Islamic ruler in the region shuffles them around on their geopolitical chessboard in order to garner praise and points but the Palestinians themselves are utterly and thoroughly disenfranchised. The tactical move would be to wipe them out but not even the Israelis are willing to go that far, blustering to the contrary. So instead they pinch them off, starve them out, and wait for them to die. 
If we agree that then wouldn't it be mixing metaphors to say that the Palestinians are the Native Arabians? Wouldn't the Jews be the natives to the area? edit: And I apologize for the ambiguity of my last question, I was writing from an old phone but now have the time and means to write more clearly. My question was "what are these plague blankets" in response to I meant to ask what you mean by that metaphor. But I understand it as the Palestinians are, tragically but factually, as helpless to Israeli claims on the land as Native Americans are to westward expansion. further edit: Thanks for the book recommendation, I will definitely look into it as I have hopes of one day visiting Iran. 1) The Jews are kicked out of Palestine by the Babylonians in the Diaspora
and eventually the plague blankets will catch up with them.
If you intend to visit Iran, also read In Search of Zarathustra
