In some manner, shape, or form, every nation state in the international system has a national security strategy or strategies. These strategies are intended to guide the state as it makes its way through the labyrinth of challenges that every nation state faces in the 21st century. The strategy could represent the nation’s overall grand strategy or it could be a national security-related strategy for one particular issue, like force structure development for the armed forces. This book discusses how nation-states create their own national security strategies, and continues to provide mandates, execution to dates, and issues involved for Congress in national security strategies.
