When President Obama visits Israel this week, he will attempt neither to unmoor the old peace process nor outfit a new one. But with new leverage in hand, a determined Secretary of State John Kerry at the helm, and riding a wave of domestic and worldwide popularity, the president may never have stronger winds at his back in the search for Israeli-Palestinian peace. To take advantage of them, he will soon need to open his sails. If the president hopes to ever make any real headway, however, he should first rid his outlook of an old trope that has become an excuse for inaction: the idea that "The U.S. cannot want peace more than the parties themselves."
