George Friedman at Stratfor has an in-depth analysis of what Israel, America, and the Arab regimes want from the Middle East "peace process". It's a great overview of the players, what they want, and how they're constrained by reality.
In the end, this is a classic study in the limits of power. Israel can have its freedom of action anytime it is willing to pay the price for it. But Israel can’t pay the price. Netanyahu is coming to Washington to see if he can get what he wants without paying the price, and we suspect strongly he knows he won’t get it. His problem is the same as that of the Arab states. There are many in Israel, particularly among Netanyahu’s supporters, who believe Israel is a great power. It isn’t. It is a nation that is strong partly because it lives in a pretty weak neighborhood, and partly because it has very strong friends. Many Israelis don’t want to be told that, and Netanyahu came to office playing on the sense of Israeli national power.
So the peace process will continue, no one will expect anything from it, the Palestinians will remain isolated and wars regularly will break out. The only advantage of this situation from the U.S. point of view it is that it is preferable to all other available realities.
