This clear and concise new edition offers a comprehensive comparison of national, international, and human security concepts and policies. Laura Neack skillfully argues that security remains elusive because of a centuries-old ethic insisting that states are the primary and most important international actors, that they can rely ultimately only on themselves for protection, and that they must keep all options on the table for national security. This is particularly apparent with the increase in glocalized terrorism and the forced migration of millions of people. Although security as a concept can be widened to encompass almost any aspect of existence, Neack focuses especially on security from physical violence. Case studies throughout bring life to the concepts. New cases in this revised edition include the Syrian refugee crisis and the responses from European states, the growth and reach of jihadist terrorist groups and the unilateral and multilateral military actions taken to confront them, drug trafficking organizations and the Mexican government's failure to protect citizens, the overt use of preventive war by major and regional powers and the increasing American reliance on drone warfare, multilateral train-and-assist operations aimed at peacekeeping and counterterrorism in Africa, UN civilian protection mandates in Libya and Cote d'Ivoire and their absence in Syria, and how terrorism and refugee crises are intimately connected. The first edition of this book was published under the title Elusive Security: States First, People Last in 2007.
