“This assessment of the strategic forces balance employs the methodology Andrew W. Marshall developed during his tenure as the director of the Pentagon’s Office of Net Assessment (ONA), a position he held for over 40 years following its founding in 1973. But while Marshall offered a definition of net assess- ment, he persistently refused requests to provide a definitive structure for how to craft one. This is easily understandable when one realizes that there are different kinds of net assess- ments: regional, functional, and technical. Moreover, by refusing to provide a cookie-cutter process for net assessments, Mar- shall left the door open to improve upon the methodology.”

In The Last Warrior, Andrew Krepinevich and Barry Watts—both former members of Marshall’s staff—trace Marshall’s intellectual development from his upbringing in Detroit during the Great Depression to his decades in Washington as an influential behind-the-scenes advisor on American defense strategy. The result is a unique insider’s perspective on the changes in U.S. strategy from the dawn of the Cold War to the present day.
