Terrorism: Commentary on Security Documents is a series that provides primary source documents and expert commentary on the worldwide counter-terrorism effort. 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), and case law 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 124, U.S. Approaches to Global Security Challenges, analyzes U.S. strategy toward security threats across the globe and identifies the beginnings of a shift away from a reliance on military power to the application of various types of civilian power which utilize a multinational approach. The documents introduced by Douglas Lovelace include U.S. perspectives on the international security situation generally as well as reports on more specific topics, such as the security situation in Afghanistan, terrorism in East Africa, the evolving role of NATO, and cooperation between the U.S. and other governments (such as the EU and China) in the fight against terrorism.
