Outstanding anthology exploring the full array of military and non-military factors--political, economic, historical, social, cultural, demographic, environmental, technological--that influence national and international security problems. All of the contributors are widely recognized and widely published, and all have some connection to Georgetown University--the home of the largest academic center for security studies in the United States. Highlights include John McNeill's chapter on environmental change and security, and Roy Goodson's chapter on transnational crime, corruption, and security. Michael E. Brown, director of the security studies program at Georgetown, is co-editor of the journal International Security (Harvard University Press), the leading academic journal in the security studies field. He was for several years co-editor of the leading book series on security studies, published by MIT Press, while he was teaching at Harvard. This is not simply another book about terrorism. Rather, this rich book has three objectives: to advance understanding of current threats to national and international security; to assess the prospects for the next decade or two and to derive policy lessons that will foster national and international security in the future. As Brown and the contributors make clear, security is not just a military issue.
