Space Warfare and Defense: A Historical Encyclopedia and Research Guide provides comprehensive coverage of the development of space as a possible arena for warfare, exploring the military uses of space--past, present, and future--and specific details of actual space weapons systems. The encyclopedia spans the breadth of U.S. military space policy; comparable programs in the Soviet Union, China, and the European Union; and the full array of international agreements designed to regulate the military uses of space. In addition, the encyclopedia includes an extensive reference guide (nearly 40 percent of the book) directing readers to the essential literature on space weapons and defense systems produced by the United States, other governments, research institutions, and additional sources. At a time when space is becoming an increasingly important place of military competition and potential conflict, Space Warfare and Defense dispels the myths and examines the realities of what may become humanity's ultimate battlefield.

Human experience with nuclear, biological, and chemical (NBC) warfare has been limited, especially in comparison to conventional forms of warfare. Our experience with nuclear warfare is confined to a period of less than one week during the end of World War II, when the United States successfully used two nuclear weapons against targets in Japan. The course of biological warfare and modern use of biological weapons are difficult to track owing to the difficulty of differentiating deliberate use from natural outbreaks. However, the keen potential of biological weapons in acts of terror was shown in the mass disruption caused in the fall 2001 experience in the U.S. with the release of anthrax through the American postal system. Chemical weapons have been used in a handful of conflicts since their introduction to modern warfare during World War I, most recently during the Iran-Iraq War during the 1980s. Despite this limited experience, NBC warfare continues to exert a certain fascination among states. The A to Z of Nuclear, Biological, and Chemical Warfare covers the development and use of NBC weapons as well as efforts to limit or control the use of these weapons through a chronology, a bibliography, an introductory essay, and dictionary entries. Over 500 cross-referenced dictionary entries provide a unique selection of terms related to NBC warfare, ranging from basic descriptions of substances used in NBC warfare to details on incidents and episodes where NBC weapons were used. Entries are structured around historical events, persons important to NBC warfare, countries where such weapons have been developed or used, and international treaties and treaty-related organizations.

There is a wide spectrum of potential threats to the U.S. homeland that do not involve overt attacks by states using long-range missiles or conventional military forces. Such threats include covert attacks by state actors, state use of proxies, independent terrorist and extremist attacks by foreign groups or individuals, and independent terrorist and extremist attacks by residents of the United States. These threats are currently limited in scope and frequency, but are emerging as potentially significant issues for future U.S. security. In this comprehensive work, Cordesman argues that new threats require new thinking, and offers a range of recommendations, from expanding the understanding of what constitutes a threat and bolstering Homeland defense measures, to bettering resource allocation and improving intelligence gathering and analysis. No pattern of actual attacks on U.S. territory has yet emerged that provides a clear basis for predicting how serious any given form of attack might be in the future, what means of attack might be used, or how lethal new forms of attack might be. As a result, there is a major ongoing debate over the seriousness of the threat and how the U.S. government should react. This work is an invaluable contribution to that debate.
