Regardless of where you stand on the issue of Israeli-Palestinian peace, it's difficult to see what the Obama administration hopes to achieve with its harsh rhetoric toward Israel, other than set itself up for another climb down. There doesn't appear to be any indication that Netanyahu will disavow building in East Jerusalem (something no Israeli prime minister would ever do). Earlier rhetoric aimed at coaxing the Netanyahu government to toe the U.S. line have failed. So what happens next? If the Israelis don't back down and offer some kind of face-saving concession, that means the U.S. backs down. That's not a fruitful dynamic to have on the eve of indirect peace talks. The Israelis will lose more trust in their U.S. interlocutor and the Palestinians will believe that the U.S. won't be able to "deliver" Israel if negotiations advance toward settlement.
And just as a general aside, how many countries respond to public hectoring?
