In From Lambs to Lions, Thomas Preston examines current trends in the proliferation of nuclear and biological weapons capabilities, know-how, and technologies for both state and non-state actors-and then projects these trends over the coming ten to fifteen years to assess how they might impact existing security relationships between states. For answers to questions about security in the face of biological and nuclear weapons proliferation, and for some potentially surprising reassurances, this clear and informative book will be invaluable.
