Ambassador Sherman will deliver the Ambassador Dave and Kay Phillips Family International Lecture at 6 p.m. in the Sanford School of Public Policy's Fleishman Commons. The lecture is free and open to the public. In the talk, "Negotiating Change: The Inside Story Behind the Iran Nuclear Deal," Amb. Sherman will reveal details of the process that ultimately earned her the National Security Medal. Peter Feaver, Duke professor of political science and public policy and director of the university's Program in American Grand Strategy, will host the discussion. "She has spent more time with Iranian counterparts than any other senior American leader," Feaver said, "and thus has a unique perspective on how the deal emerged and what it means for geopolitics today and in the coming years." As undersecretary for political affairs from September 2011 to October 2015, Sherman led the series of U.S. negotiations with Iran that culminated in an agreement last July. Now a senior fellow at both Harvard's Institute of Politics and Belfer Center for Science and International Affairs, Ambassador Sherman recently stepped down as Undersecretary of State for Political Affairs after four years overseeing every region of the world, dealing with every major opportunity and crisis, and, leading the U.S. negotiating team to a successful conclusion of the Iran nuclear deal.
