There is one much more important thing which must be done for the whole process to succeed and not end in failure as seems today. It is an agreement on what happens after there is an agreement on the final status. For example an agreement that following an agreement on final status there will be negotiations on a detailed staged implementation agreement. Without such an agreement Israel will not allow an agreement to be reached. The security risk of a quick implementation following an agreement on the final status is just too high. No Israeli prime minister will take such a risk. It will also be impossible for the coalition to survive an attempt to implement such a peace. On the other hand and implementation agreement whith stages which each side carries in turn will allow observing that the creation of a functional Palestinian state is on track. If it is not, the process will be stopped. It will also allow seeing whether there is popular support for a true peace.
