Barak thought he had a deal and Arafat nixed it. Olmert thought he had a deal, Abbas nixed it. They just do not want a settlement, whether its because of pressure from Syria and Iran and possibly Egypt (as was the case with Arafat) or they just want to keep sucking money from the west because they don't believe they can stand on their own feet. It is about time the worlds blamed the Palestinians, and the Arab world. I would bet though that it's the Arab world that is nixing every peace effort. We hear their English pronouncements for peace but we also hear their refutations of the English pronouncement once they speak in Arabic.
