This dictionary is a wonderfully concise and comprehensive resource on a very important topic. It provides a thorough and lucid set of definitions in a subject area which too frequently has been ``left to the experts.'' In 268 detailed entries, the authors provide a wealth of information on such topics as the arms race, conventional and nuclear weapons, nuclear strategy, and disarmament. The entries are cross-referenced and an index is provided. Each entry provides definitions of words and concepts, as well as paragraphs on historical context and current significance. This book will be of great value to general readers as well as specialists, and will be indispensable in both academic and public libraries.-- Jennifer Scarlott, World Policy Inst., New York - Library Journal.
