Israel's "centerists", such as they are, have no problem with expanding the settlements and crowding Palestinians off the map. They prefer to play a passive role in this, letting the right wingers do all the heavy lifting and play point. The centerists will just come along for the ride, taking comfort in the fact that their role concerning the Palestinians is technically, "live and let live" . Since there is no real left wing in Israel and the centerists are happy to keep their silence, there is nobody to temper the unreasonable demands and goals of Israels extreme right.
