Terrorism: Commentary on Security Documents is a series that provides primary source documents and expert commentary on various topics in the worldwide effort to combat terrorism. Among the documents collected are transcripts of Congressional testimony, reports by such federal government bodies as the Congressional Research Service (CRS) and the Government Accountability Office (GAO), United Nations Security Council resolutions, reports and investigations by the United Nations Secretary-General and other dedicated UN bodies, and case law from the U.S. and around the globe covering issues related to terrorism. Most volumes carry a single theme, and inside each volume the documents appear within topic-based categories. The series also includes a subject index and other indices that guide the user through this complex area of the law.Volume 127, The Changing Nature of War, tackles how the approach to training for and fighting wars and readying national security is likely to evolve as the United States moves further into the 21st Century. Professor Douglas Lovelace, Jr. has organized and provided framing and illustrative commentary on Congressional Research Service reports, Presidential policy statements, Department of Defense strategy papers, and research reports from the U.S. Army War College's Strategic Studies Institute on contemporary national security topics as: United States war planning; the inter-related policy and force-related concerns of shifting from counterinsurgency-based efforts abroad to a focus on counterterrorism both domestically and abroad; transnational organized crime, with particular emphasis on the Mexican drug cartels operating along the U.S.-Mexico border; and the ever-expanding national security and private economic ramifications of cyberwarfare.
