"the only document that recognizes Gaza and the West Bank as one legal entity is the Oslo accords." - irrelevent, since that issue can be put on the agenda of ANY talks. "it is difficult to conceive of any potential negotiations not based on Oslo" - the PLO is bound by its agreements at Olso, so this is a given. "If Hamas refuses, it has no legal standing for a state." - a nonsense. Hamas has said that it does not seek a seat at negotiations; that is the PLO's job. And Hamas is right. It is a political party that is in control of a local government entity - the PA. It (and the PA) does not speak for the Palestinian people, and does not pretend to. You may as well insist that the Mayor of Jerusalem's political opinion be taken into account. His opinion doesn't matter at all, since he can't sign any agreement with the Pals - any more than Hamas or the PA can sign any agreement with the Israelis. Only the PLO can do that.
