This is a good idea. It is outside the box. It undercuts opppositon on both sides.
The current round of Isreali-Palestinian negotiations will be as successful as the previous. Almost as successful as Doha or the recently concluded aid conference in New York City. Even Hamas would have trouble dealing with this idea because opposing it would reveal to the world exactly what everyone knows - that it is nothing but a gang of terrorists who happen to have gotten control over a piece of land by promising the people of Gaza ultimate victory - no economy, but ultimate victory.
Worth a try.
