The PA is right. There must be a deadline for a final agreement. Indeed, the time to hold the conference is AFTER everything is agreed upon so that all parties can commit to the agreement and to its enforcement. This conference, on the other hand, is merely for the benefit of Bush and Olmert. Bush benefits by showing how committed he is to peace and to offset his true image as a war criminal. For Olmert it is a way to help Bush, to defer taking substantive actions, and most of all to gain implicit Arab recognition of Israel in return for doing nothing.
