The book examines the evolving nature of national and international security in the post-Cold War era, focusing on non-military threat potentials and how these may best countered. Six specific issues are discussed: terrorism, the heroin and cocaine trade, privacy, environmental degradation, the spread of disease, and uncontrolled migration. The book concludes that greater national coordination, inter-agency cooperation, and international collaboration is needed if these problems are going to be dealt with effectively.
