These 'leaks' are just the usual carefully crafted agitprop that we have come used to in the mainstream media. Anyone who wants to be informed about the details of the many power struggles in the Middle-East reads academic journals, follows the statements by the foreign ministries closely, and corresponds with the negotiators, which is surprisingly easy and informative. The fact that the mainstream media fails to inform the public well is caused by human inability to grasp the consequences of other societies (America, Europe, Middle-East) being different in structure. Both the inability of journalists as well as readers/watchers.
The only real problem upholding an agreement between Israel and the Arab population in the former British mandate of Palestine are neighboring countries of which the leadership cannot tolerate a democratic flourishing Arab state, because it would undermine the stability of their own rule. We once had a semi democratic Arab state that did well, which was Lebanon. We all know how that was finished by rulers like al-Assad.
Once the price of oil gets below $25 a barrel for a sustained period of time, countries like Iran will no longer be able to spend billions of dollars per year in destabilizing Gaza and the West Bank and other territories. It is horrible to see that the governments in Europe and the US fail to address their opponents in the Middle-East, while a few dictators find our weak spots consistently and exploit them to the fullest.
