This is a clear, non-technical and comprehensive study of nuclear strategy and the balance of power. The book is intended for both supporters and opponents of nuclear deterrence--indeed for all who believe that nuclear issues cannot be wished away or laid aside but must be addressed with knowledge, even if this means thinking about the unthinkable. Within a coherent system of thought, this volume addresses the most fundamental issues of our time, such as the first-strike advantage, arms-control agreements, the Star Wars program, the "nuclear winter" hypothesis, and nuclear conflict itself. The book is packed with valuable factual information, including notes, diagrams, illustrations, and appendices.
