Book excerpt: Arms control and disarmament are key elements in promoting international peace and security. In recent decades the scope of disarmament law has broadened from a traditional focus on weapons of mass destruction to encompass conventional weapons. In this new volume in the Elements series, Stuart Casey-Maslen provides a concise and objective appraisal of international arms control and disarmament law. In seven concise chapters, he traces the history of arms control and disarmament in the modern era, addressing the issues surrounding biological and chemical weapons, the Non-Proliferation of Nuclear Weapons, and conventional weapon and arms transfer regimes. He concludes by considering how, in order to remain relevant, disarmament and arms control will need to adapt to rapidly evolving technologies that defy traditional means of verification and control. Arms Control and Disarmament Law is an accessible, go-to source for practicing international lawyers, judges and arbitrators, government and military officers, scholars, teachers, and students.
