The seventh edition of this highly successful textbook analyzes the history, evolution, and processes of national security policies.
It examines national security from two fundamental fault lines - the end of the Cold War and the evolution of contemporary terrorism dating from the 9/11 terrorist attacks - and traces their path up to ISIS and beyond. The book considers how the resulting era of globalization and geopolitics guides policy. Placing these trends in conceptual and historical context and following them through military, semimilitary, and nonmilitary concerns, National Security treats its subject as a nuanced and subtle phenomenon that encompasses everything from the global to the individual with the nation at its core.
