The great philosopher of war Carl von Clausewitz analyzed this problem, discussing what he called “the culminating point of victory”—the optimum moment to end the war. To recognize the culminating point of victory, you must know your own resources, how much you can handle, the morale of your soldiers, any signs of a slackening effort. Fail to recognize that moment, keep fighting past it, and you bring on yourself all kinds of unwanted consequences: exhaustion, escalating cycles of violence, and worse.
