There has never been one. It started out with hope but Obama lacked the strength and discipline to nail Israel to its obligations under International Law and Israels previously signed agreements which Israel these days calls pre conditions. With the loss of Fayyad it does not spell the end. Does a country end when a Prime Minister leaves office?...no of course not. A new person is elected and the country moves on. If the PA does collapse then Israel will have spiralling costs of the entire occupation without PA help. Israel as we saw from the Lapid budget commentary, is strapped for cash as it is. Full responsibility for the Occupation could well bring Israel down and it will get no International Support.
