One look at a map will show you that Israel's own mantra about "defensible borders" makes Ariel a dead-duck i.e. you can't loop the border around Ariel and still claim that such a border loop can be defended. "other settlement blocs - Gush Etzion, Maaleh Adumim and the Jewish neighborhoods around Jerusalem - will remain in Israeli hands in a future agreement" Settlements that sit off the two "shoulders" of Jerusalem are arguable. Those that exist merely to cut off Jerusalem from the West Bank are not; the Pals simply can not accept an arrangement that leaves their capital choked off by Israeli "settlements". Those will have to go, and if the Americans press Abbas to concede on those then he should get up and walk out.
