I totalluy agree! But unfortunately that is probably the same argument that prevents this Israeli administration from doing so. Netanyahu doesn't want a fair peace agreement, one that Barghouti would probably be able to reach. Remember Netanyahu is the same person who, on CNN during the First Gulf, was showing the map of Israel, which included Gaza and the Occupied Territories blattering about how the Palestinians already had a country: Jordan!
Dozens of Zionist Union activists call on Netanyahu to resign in Tel Aviv protest (Haaretz)
