rabid Jewish supremacist fruitcakes in their midst? An aggressive, lawless, arab-hating 5th column? (50,000 assumes that the other 50,000 east of the security barrier are semi-sensible, which is admittedly a highly debatable point). Beating up the locals, burning olive groves in order to drive people off the land and steal it, torching mosques and so on? Are the 'demilitarised' Palestinians to police, protect and arrest them and how would that play with (a) the other settler supremacists and (b) the shrill supremcists who form a majority in Israel? Would it not just be an excuse for constant cross-border intervention by the IDF and continual Israeli meddling in Palestinian affairs, which Israelis would love because they would look important and their leaders could pose as decisive? No, all 24 illegal outposts that Israel undertook to demolish under the roadmap need to be vacated, ditto the other 30+ that have been allowed to spring up since. Because of the criminal antics of the right, any Jew remaining in Palestine would have to (a) have a non-criminal record, (b) be disarmed and (c) sign a good conduct pledge which, if broken would lead to their expulsion back to Israel-Brooklyn-Moldova. But even then, the Pals don't have anything like the forces to guard and police close to 100 unruly settlements, which will get even 'unrulier' when Pals start legal action to retrieve land stolen from them or built on illegally. Don't see much future for settlers beyond the security barrier.
