We are at a time when international law and the law of war are particularly important. The testing of nuclear weapons that is being used in the rhetoric surrounding threats of war is creating new fears and heightening current tensions. Richard Falk has for decades been an outspoken authority calling for nuclear disarmament and the enforcement of non-proliferation treaties. In this collection of essays, Falk examines the global threats to all humanity posed by nuclear weapons. He is not satisfied with accepting arms control measures as a managerial stopgap to these threats and seeks no less than to move the world back from the nuclear precipice and towards denuclearization. Falk's essays reflect the wisdom and innovative thinking he has brought to his long career as a scholar and activist, as he reminds nuclear weapons states of their obligation under international law and moral imperative to seek nuclear disarmament.
