Richard Betts’ 1995 book, Military Readiness: Concepts, Choices, Consequences, was extensively cited in War on the Rocks (3/15/21) by the Chief of Staff of the Air Force and Commandant of the Marine Corps, who argued that the “current readiness model strongly biases spending on legacy capabilities for yesterday’s missions, at the expense of building readiness in the arena of great-power competition and investing in modern capabilities for the missions of both today and tomorrow.”  You can read their piece, entitled “Redefine Readiness or Lose”, here.
