This book focuses on an even more urgent and inconvenient truth than global warming. At the nuclear precipice, humanity s choices are catastrophe or transformation. This book explores the present nuclear predicament, and how to step away from the precipice and assure humanity s future. It examines the intersections between international law and national policies; and between nuclear proliferation, nuclear terrorism and nuclear disarmament. The book offers a way out if policy makers of leading countries can summon the vision and political will to move in a new direction."
