This Perspective examines the gap between U.S. defense aspirations and the reality of current policy. In this Perspective, the author surveys grand strategy principles that call for a U.S. ability to project power to help deter major war in key regions, defines the U.S. defense strategic approach of the post–Cold War era and its key assumptions, and explains the reasons why these assumptions are no longer valid. The author suggests six leading barriers to reform—reasons why the U.S. Department of Defense’s responses have been unable to generate the degree of change required. The Perspective concludes with a description of principles of a new U.S. defense strategy.
