This book recapitulates and extends Ned Lebow’s decades’ long research on conflict management and resolution. It updates his critique of conventional and nuclear deterrence, analysis of reassurance, and the conditions in which international conflicts may be amenable to resolution, or failing that, a significant reduction in tensions. This text offers a holistic approach to conflict management and resolution by exploring interactions among deterrence, reassurance, and diplomacy, and how they might most effectively be staged and combined.
