In May 2011, Robert Art (Brandeis University, Politics), Barry Posen (MIT, Political Science), William Hitchcock (University of Virginia, History), and Jeremi Suri shared their work on U.S. grand strategy with a group of diplomats, think-tank researchers, and scholars at a seminar convened by the Tobin Project and Georgetown University’s Institute for the Study of Diplomacy. Participants – including former U.S. diplomats Dr. Chester Crocker, Ambassador Howard Schaffer, and Ambassador Donald McHenry – discussed contemporary and historical aspects of grand strategy as well as the role of diplomacy in strategy.
