Peter Beinart writes: The organized American Jewish community has spent decades building influence in Washington. But it’s succeeded too well. By making it too politically painful for Obama to push Netanyahu toward a two-state deal, the American Jewish establishment (along with its Christian right allies) is making Washington irrelevant. For two decades, the core premise of the American-dominated peace process has been that since only America enjoys leverage over Israel, the rest of the world should leave the Israel-Palestinian conflict in America’s hands.

But across the world, fewer and fewer people believe Washington will effectively use its leverage, and if the Kerry mission fails, Washington will no longer even try.

For two decades, AIPAC and its allies have successfully pushed a harder and harder American line against Iran’s nuclear program. In Congress, where a bipartisan group of senators has just introduced new sanctions legislation over White House objections, that hard-line agenda remains popular. But in the country at large, it risks alienating the Americans who will dominate politics in the decades to come.
