My enemy's enemy is my friend? It's a line that's pervaded discussions this week about the possibility that the United States and Iran teaming up to address a rapidly destabilizing Iraq.
In an interview with Yahoo! News on Monday, Secretary of State John Kerry said simply that the U.S. would be "open to discussions" if it seemed "something constructive" could come from a collaboration with Iran.
But on CBS, news form U.S. Ambassador to Iraq Ryan Crocker suggested caution.
“This is a sectarian struggle and if we are seen as cooperating too closely with Iran it is going to further alienate the Sunni element of the Iraqi population," said Crocker.
Hillary Mann Leverett, co-author of "Going To Tehran: Why America Must Accept the Islamic Republic of Iran" and a senior lecturer at American University's School of International Service, joins The Takeaway to weigh in.
