If the Quartet wants a realistic proposal, they should take into account that Israel is dominated by the right-wing, people who don't want to give up the West Bank. They should therefore issue a type of "threat", such as: If negotiations have not been concluded by October of next year, the Quartet will recommend to the Security Council a unilateral decision on all the issues still outstanding, including Jerusalem, borders, refugees, etc. This will get even Israel moving, since this will allow Obama to act after the US elections in early November. Even if he loses, he still remains President until Jan 20th.
