The handful of Palestinians I've met haven't been terrorists. Christians mostly. I myself, wouldn't be opposed if Israel decided to fly these Palestinians in by the planeful from the USA. I would say the prerequisite would be no terrorist ties and no overt political activity on behalf of terrorists. No reason why not. Besides if Israel can't keep a majority of the population Jewish, they certainly have enough Christians around to at least keep a Judeo-Christian majority. Gotta think about things in the long run.
