While wars invariably end, the underlying disagreements often remain. The peace is tenuous and interrupted by spasms of violence. The way a war ends—whether through outright victory, exhaustion or mutual deterrence—might make a difference, with exhaustion less likely to prevent future flare-ups than, say, the wholesale defeat of one party. But this is not guaranteed. It certainly does not mean that some types of peace are not worth pursuing.
