To believe in this process, as Kerry envisions it, you have to blind yourself to at least two realities.

The first is that Hamas exists and is in control of the Gaza Strip, whether we like it or not. Abbas’s Palestinian Authority, which will be bargaining with Israel, will represent at best half of Palestine. How do you negotiate a state into existence that is divided between two warring factions? It isn’t even clear if the Palestinian Authority is fully in control of those parts of the West Bank that Israel deigns to let it control. (I will save for another time the deeper discussion of whether the maximum an Israeli government could offer the Palestinians represents the minimum the Palestinians could plausibly accept.)

You also have to blind yourself to the reality that the Jewish settlement movement on the West Bank is now the most powerful political force in Israel. This is a movement whose leaders and Knesset representatives and cabinet ministers will subvert any peace process that would lead to the dismantling of even a single settlement, including any of the dozens of well-populated ones far beyond Israel’s West Bank security barrier.

Oh, and by the way, to believe in this process you have to believe that the parties are ready to divide Jerusalem.
