The fate of east Jerusalem will be decided only hrough bilateral negotitations. If all of east jerusalem was an integral part of a so called non existent palestinian state, there was no need for negotiating it. However, there is need for negotiations. Most maps, (americans, the quartet, palestiniasn israelites) regarding the possible solution in regards to Jerusalem are already desdigned. That means that negotiations will focus on details. In none of these maps Israel returns to the 67 borders. That means that parts of east Jerusalem will be annexed.
