Actually, they can blame quite a few groups of people, starting of course with their parents and going up through Hamas and UNRWA.

Since the Israelis are the land's real indigenes, maybe they should copy what some native peoples here did: kidnap little white (Arab) ones and bring them up as Israeli Jews. Not one 'white' child brought up as a native wanted to return to white society! Any bets that the same thing will be observed among such children once they're grown? I will!
