That last move might be a long shot as well, but Mr. Netanyahu has already started saying things his allies like to hear. After his session on Thursday with David Cameron, the British prime minister, Mr. Netanyahu said he was ready to meet with President Mahmoud Abbas of the Palestinian Authority in the occupied West Bank even though it is “a nightmare for my security people.”“I’m willing right now, without any preconditions, any preconditions whatsoever, to sit down with President Abbas and negotiate this peace,” Mr. Netanyahu said. “I’m willing to go to Ramallah,” he added, “or President Abbas can come to Jerusalem, or, for God’s sake, we can take up some of these suggestions for retreats in Sicily or fjords in Norway, whatever. Anytime, anywhere, now, without preconditions.”
