It would be a start, but the other "well armed" States would have to be part of the process. The Moderate/Oil States would have to back it, and they would have to commit large amounts of funds to build a Palestinian State. Maybe the UN should monitor it for a while to make sure that all of the agreements are observed? Without these things, it will not work. What the Palestinians think about a one state solution is irrelevant.
