Biography
Barry R. Posen is Ford International Professor of Political Science at MIT and serves on the Executive Committee of Seminar XXI. He has written three books, Restraint-A New Foundation for U.S. Grand Strategy, Inadvertent Escalation: Conventional War and Nuclear Risks and The Sources of Military Doctrine. The latter won two awards: The American Political Science Association's Woodrow Wilson Foundation Book Award, and Ohio State University's Edward J. Furniss Jr. Book Award. He is also the author of numerous articles, including "The Case for Restraint," The American Interest, (November/December 2007) and "Command of the Commons: The Military Foundation of U.S. Hegemony," International Security, (Summer, 2003.) He has been a Council on Foreign Relations International Affairs Fellow; Rockefeller Foundation International Affairs Fellow; Guest Scholar at the Center for Strategic and International Studies; Woodrow Wilson Center Fellow; Smithsonian Institution; Transatlantic Fellow of the German Marshall Fund of the United States, and most recently Visiting Fellow at the John Sloan Dickey Center at Dartmouth College.
Research
Professor Posen studies U.S. grand strategy and national security policy. His current research examines whether the diffusion of power away from the United States can best be understood as the emergence of a multipolar structure of power, and if so, how the United States should navigate this change.
Posen’s project aims to research the “rules of the road” of 21st Century multipolarity. To do so, he looks at how states and statesmen navigated multipolar systems in the past. But there are limits to drawing lessons from history, due to the truly global nature of a future multipolar system, if it emerges. Further, nuclear weapons have changed security competition among states, and the past half-century has seen major changes in conventional warfare as well. Posen aims to imagine the kind of multipolar security competition that might prevail, given these changes. Posen published an article exploring the impact of multipolarity on the management of civil wars in Daedalus (Fall 2017).
Posen continues to study current U.S. national security policy. He published his interpretation of the grand strategy of the Trump Administration, "Illiberal Hegemony," in Foreign Affairs (March/April 2018). And he contributed to the debate on how to address the North Korean nuclear weapons program in the New York Times."The Price of War With North Korea" (December 2017). He remains actively engaged in the debate on U.S. Grand Strategy, promoting Restraint whenever there is an opportunity. Finally, he follows European security issues, and lives in hope that one day Europeans will assume responsibility for their own security.
