This monograph offers key considerations for DoD as it works through the on-going defense review. The author outlines eight principles for a risk management defense strategy. He argues that these principles provide “measures of merit” for evaluating the new administration’s defense choices. This monograph builds on two previous works—Known Unknowns: Unconventional “Strategic Shocks” in Defense Strategy Development and The New Balance: Limited Armed Stabilization and the Future of U.S. Landpower. Combined, these three works offer key insights on the most appropriate DoD responses to increasingly “unconventional” defense and national security conditions. This work in particular provides DoD leaders food for thought, as they balance mounting defense demands and declining defense resources.
