Over the past fifteen years, The Spread of Nuclear Weapons has been a staple in International Relations courses because of its brevity and crystal-clear explanations. The new edition, An Enduring Debate, continues the important discussion of nuclear proliferation and the dangers of a nuclear-armed world. With new chapters on the questions surrounding a nuclear North Korea, Iran, and Iraq and the potential for a world free of nuclear weapons, this Third Edition will continue to generate a lively classroom experience.
