Mitchell: For Obama, Iran’s His Last Chance at a Foreign Policy Victory

ALEXANDER: "Of course, political consequences as well?" 
MITCHELL: "Yeah, this is a legacy issue clearly for Barack Obama. What else is working well in foreign policy, with the withdrawals from Iraq and Afghanistan have not exactly gone as predicted. ISIS and all of those threats, the failures in Yemen and Libya, this is a big deal. And John Kerry has put his heart and soul into this after the failure of the Middle East peace talks, this is it, Peter. Thank you."
