Christopher A. Preble contends that the vast military strength of the United States has induced policymakers to broaden the perception of the “national interest.”

Christopher Preble is senior fellow and director of the Reimagining US Grand Strategy Program at the Stimson Center. He is the author of Peace, War, and Liberty (2019) and co-​author, with John Glaser and A. Trevor Thrall, of Fuel to the Fire: How Trump Made America’s Broken Foreign Policy Even Worse (and How We Can Recover) (2019). Preble was formerly the vice president for defense and foreign policy studies at the Cato Institute, and he holds a PhD in history from Temple University.

Numerous polls show that Americans want to reduce our military presence abroad, allowing our allies and other nations to assume greater responsibility both for their own defense and for enforcing security in their respective regions. Why haven’t we done so? In The Power Problem, Christopher A. Preble contends that the vast military strength of the United States has induced policymakers in Washington to broaden the perception of the “national interest,” and ultimately to commit ourselves to the impossible task of maintaining global order.

Preble holds that the core national interest — preserving American security — is easily defined and largely immutable. In his view, military power is purely instrumental: if it advances U.S. security, then it is fulfilling its essential role.
