Egypt is also pretty much in the pockets of the state of Israel and the US economically. A significant minority of all Egypts perishable foodstuffs are grown in Israel, and Egypt also receives almost as much US aid as the state of Israel does. Jordan is never going to be a problem, Syria will probably only return to a semblance of cohesion after decades (so no assurances there), and Lebanon is only interested in retaining its' own borders.
The problem, as it always has been, lies with the nationalist Zionist/revisionist Zionist claim that the state of Israel's territories must include the entirety of the old kingdoms of Judaea and Samaria - in other words, an Israel which includes parts of Egypt, Iraq and Saudi Arabia, and most of Syria, Jordan and Lebanon. While the Palestinians and the Arab nations might favour a return to the '47 or even the '67 borders, the state of Israel will never favour such a thing. They want it all, and this is evident from the constant expansion of settlements in the West Bank, and the ever-increasing encroachment into Gaza. All these peace talks; all they do is buy the state of Israel more time to build "facts on the ground".
