On August 6, 1945, an atomic bomb was dropped on Hiroshima, instantly killing up to 80,000 civilians, with another 40,000 dying soon after from burns and radiation poisoning. The bombings of Hiroshima and Nagasaki led to the surrender of the Japanese Army, marking the end of the most destructive war in history.

War has been a constant throughout history. Since the dawn of agriculture, humans have waged war against one another. Some argue that war is ingrained in human nature, from our ancestors battling over resources and empires seeking expansion, to biblical genocides and acts of human sacrifice—Homo sapiens are seemingly insatiable for conflict. Others, however, believe war is not inevitable and that we have the capacity for humility, justice, and kindness without resorting to armed conflict.

We must remember that explaining war is not the same as justifying it. While pacifism, as exemplified by Jesus and Gandhi, is often seen as noble, is non-violence truly effective against regimes intent on ethnic cleansing? If not, how do we determine when war is justified and what defines proportional force? Can the killing of innocent civilians ever be justified? And, if not, how do they differ from innocent combatants? War, huh, good god, what is it good for?
