How should we judge wartime atrocities?: The Story

The room

Concrete walls, bad coffee, a long table, August 1945. A map of the Japanese home islands pinned to the wall. On one side: casualty projections for Operation Downfall — 250,000 to over a million Allied dead. Japanese casualties several times that. On the other: a single device, tested once in the New Mexico desert three weeks earlier. The people in the room are deciding how many people to kill. The only question is which number is smaller.

On August 6, the Enola Gay dropped Little Boy on Hiroshima. Between 70,000 and 80,000 died instantly. By year’s end, approximately 140,000. Three days later, Fat Man killed roughly 70,000 in Nagasaki. Japan surrendered August 15. Truman later said the decision was not difficult. Whether he was lying or telling the truth, each possibility is horrifying in its own way.

The forgotten fire

The fire raids killed more and generated less debate. On March 9, 1945, 334 B-29s dropped incendiary clusters on Tokyo. Roughly 100,000 civilians burned to death in six hours — more than either atomic bomb would kill on impact. Curtis LeMay, who planned the raid, later said that if the United States had lost the war, he would have been tried as a war criminal. He was not wrong about the asymmetry. The firebombing of sixty-seven Japanese cities was already killing civilians at industrial scale before the bomb existed.

The absolute moralists hold that deliberately targeting civilians is a line no calculus can cross — Hiroshima was murder regardless of what it prevented. The contextualists have read Stimson’s diary and the intercepted cables showing the Japanese military’s determination to fight on beaches with sharpened bamboo. They find peacetime moral certainty a luxury purchased by the people who made the decisions. The consequentialists have done the math — the invasion toll dwarfs the atomic toll by every serious estimate. The just war reformers want to move past the Hiroshima debate entirely and build institutions that make the room unnecessary.

If a previously classified document surfaces proving the inner circle knew Japan was ready to surrender before the bombs dropped, every frame shifts. Eighty years of argument. The archive still has rooms nobody has opened.
