How and when should we end a war? What place should the pathways to a war's end have in war planning and decision-making? This volume treats the topic of ending war as part and parcel of how wars begin and how they are fought - a unique, complex problem, worthy of its own conversation. New essays by leading thinkers and practitioners in the fields of philosophical ethics, international relations, and military law reflect on the problem and show that it is imperative that we address not only the resolution of war, but how and if a war as waged can accommodate a future peace. The essays collectively solidify the topic and underline its centrality to the future of military ethics, strategy, and war.
