From the introduction: "As I continued to teach, though, I noticed another gap in the literature. The arguments policymakers and academics were making on how nuclear weapons reductions related to preventing further nuclear proliferation were, at best, uneven. Each of the basic views-official, hawkish, and academic-spotlighted some important aspect of the truth, but each was incomplete and surprisingly optimistic. [...] This brief volume covers each of these points. First, it reviews the key popular views on nuclear proliferation. Second, it considers how much worse matters might get if states continue with relatively loose nuclear constraints on civilian and military nuclear activities. Finally, it offers several policy recommendations."
