Bio

 Stephen Wertheim is a senior fellow in the American Statecraft Program at the Carnegie Endowment for International Peace. He is a historian of U.S. foreign policy and analyzes contemporary problems in American strategy and diplomacy. Wertheim is also a visiting lecturer at the School of Public and International Affairs at Princeton University.

He is the author of Tomorrow, the World: The Birth of U.S. Global Supremacy (Harvard University Press, 2020), which reveals how U.S. leaders, in the months leading up to the attack on Pearl Harbor, decided to pursue global military dominance as an effectively perpetual project. Wertheim has published scholarly research on a range of subjects and concepts in U.S. foreign policy, including humanitarian intervention, international law, international organization, colonial empire, public opinion, and “isolationism.”

Named one of “the world’s 50 top thinkers for the Covid-19 age” by Prospect magazine, Wertheim regularly comments on current events. His essays have appeared in the Atlantic, Foreign Affairs, Foreign Policy, the Guardian, the New York Review of Books, the New York Times, the New Yorker, the Washington Post, and elsewhere. He has also appeared on C-SPAN, Deutsche Welle, MSNBC, NPR, and PBS. His commentary may be viewed here.

During the 2022-23 academic year, Wertheim was a distinguished lecturer in history at Catholic University and a visiting lecturer in law at Yale Law School. He previously held faculty positions in history at Columbia University and Birkbeck, University of London, and postdoctoral research fellowships at Princeton University and King’s College, University of Cambridge. Before coming to Carnegie, Wertheim was director of grand strategy at the Quincy Institute for Responsible Statecraft, a think-tank he co-founded in 2019.

He received a PhD from Columbia University in 2015 and an AB summa cum laude from Harvard University in 2007.
