On Wednesday, October 16, 2013, the Middle East Institute hosted author and Brookings senior fellow Ken Pollack for a discussion of his book, Unthinkable: Iran, the Bomb, and American Strategy(Simon & Schuster, 2013). In his latest work, Pollack explores the protracted tensions underlying the U.S.-Iranian relationship, how it evolved to its current status, and how the U.S. should best address Iran's nuclear ambitions. Drawing on his experience as a former CIA analyst and 25 years of working on Middle East issues, Pollack addresses the key questions of the Iran nuclear issue and assesses the various policy alternatives U.S. policymakers face today.
