Christopher Preble served as co-director of the New American Engagement Initiative in the Scowcroft Center for Strategy and Security. In this role, he led a team of scholars who challenged prevailing assumptions surrounding US foreign policy, and who offered a range of policy options that went beyond the use of force and coercion. His own work focused on the history of US foreign policy, contemporary US grand strategy and military force posture, alliance relations, and the intersection of trade and national security.

Preble is the author of four books, including Peace, War, and Liberty: Understanding U.S. Foreign Policy (Cato Institute, 2019); and The Power Problem: How American Military Dominance Makes Us Less Safe, Less Prosperous, and Less Free (Cornell University Press, 2009). He co-authored, with John Glaser and A. Trevor Thrall, Fuel to the Fire: How Trump Made America’s Broken Foreign Policy even Worse and How We Can Recover (Cato Institute, 2019), and he has also co-edited several other books and monographs, including A Dangerous World? Threat Perception and U.S. National Security (Cato Institute, 2014), with John Mueller. His work has appeared in major publications including the New York Times, the Washington Post, the Los Angeles Times, the Financial Times, Survival, Foreign Policy, National Review, and The National Interest, and he is a frequent guest on television and radio.

In addition to his work at the Atlantic Council, Preble co-hosts the “Net Assessment” podcast in the War on the Rocks network, and he teaches the US Foreign Policy elective at the University of California, Washington Center. He has also taught history at St. Cloud State University and Temple University. He is a life member of the Council on Foreign Relations.

Before joining the Atlantic Council, Preble was vice president for defense and foreign policy studies at the Cato Institute from 2011 to 2020, and director of foreign policy studies from 2003 to 2011. Preble was a commissioned officer in the US Navy, and served aboard the USS Ticonderoga (CG-47) from 1990 to 1993.

Preble graduated from George Washington University in 1989 and received a PhD in history from Temple University in 2002.
