The global threat of nuclear weapons is one of today's key policy issues. Using a wide variety of sources, including recently declassified information, Nathan E. Busch offers detailed examinations of the nuclear programs in the United States, Russia, China, Iraq, India, and Pakistan, as well as the emerging programs in Iran and North Korea. He also assesses the current debates in international relations over the risks associated with the proliferation of nuclear weapons in the post–Cold War world.

Busch explores how our understanding of nuclear proliferation centers on theoretical disagreements about how best to explain and predict the behavior of states. His study bridges the gap between theory and empirical evidence by determining whether countries with nuclear weapons have adequate controls over their nuclear arsenals and fissile material stockpiles (such as highly enriched uranium and plutonium). Analyzing the strengths and weaknesses of various systems of nuclear weapons regulation, Busch projects what types of controls proliferating states are likely to employ and assesses the threat posed by the possible theft of fissile materials by aspiring nuclear states or by terrorists.

No End in Sight provides the most comprehensive and up-to-date analysis of issues at the forefront of contemporary international affairs. With the resurgence of the threat of nuclear terrorism, Busch's insights and conclusions will prove critical to understanding the implications of nuclear proliferation.
