Seriously, how close did those 15 years bring Abbas to getting the Israelis to either unoccupy or decolonize the West Bank? 15 years of nothin' is more than anybody with a brain ought to put into a one-sided 'Negotiation' that's obviously going nowhere. It's a lot more complicated than just Obama screwing it up...not that his vague and drifting foreign policy has done anything but further deteriorate an already-unproductive goat-screw, of course.
