President Obama on the Middle East and 'Arab Spring'

Speaking in Cairo two years ago, President Obama called for a "new beginning" in the Muslim Middle East based on "respect" and "mutual interest." Today, he said the so-called "Arab Spring" requires yet another "new chapter in American diplomacy," and he promised economic help to facilitate democracy. Once again, he criticized Israeli settlements. For the first time, he said a Palestinian state should be based on 1967 boundaries. Did he achieve the goal of a sweeping survey of a complex region? Can he revive American influence? We hear a variety of opinions.
