The attractiveness of unilateralism is understandable. Why make a deal with Israel that might require recognizing it as a Jewish state, taking a bit less territory on the West Bank or having to swap some pieces of land with Israel, providing Israel with security guarantees, giving up the dream of total victory and Israel's elimination, and accepting limits on your military forces when you can just demand, and possibly get, everything you want from the United States, Europe, the UN, or the international community in general?
....Of course, that means the conflict will continue, people will die, Palestinians will continue to be (or at least will be perceived as) suffering, and everything can be blamed on Israeli intransigence. There would be no peace and no Palestinian state, but that better suits the PA's current strategy and again would largely be blamed on Israel.
obviously Fatah is in no hurry for peace if they can take over through the international community, the U.N. and the E.U.... or maybe even Obama. oh and of course the fact the the Israelis seized building for their people to live in is completely ignored... because they don't want to work out a deal.
