"It does seem that there are lineages of war and that wars are the causes of wars. And it seems unlikely that wars cause peace. Wars cause victory and defeat, equivocal terms because in wars both sides lose much that they would rather keep, and they cause exhaustion. But victory, defeat, loss, and exhaustion don’t define peace. It is certain that peace does not cause war. Wars, moreover, tend not to end. Damage from our Civil War continues today. We are still under the influence of World War II. We still suffer the effects of the succession of wars that have followed."
