A National Security Strategy Primer provides students with a common point of reference for material covered in the National War College curriculum. We use the Primer as a point of departure for discussions about strategy, and as a principal tool for understanding and achieving core course learning objectives. The Primer specifically addresses the concept of national security strategy and an approach for developing it, one that should be studied closely. In addition to using current joint and service-specific doctrine, extant procedures, and existing policy guidance, A National Security Strategy Primer uses the literature on national security strategy found in academia, the business sector, and elsewhere. While the Primer is geared towards the National War College core curriculum, it can also serve as a useful tool for interagency practitioners charged with designing or assessing national security strategies.
