Abstract: Numerous polls show that U.S. public approval of Truman’s decision to drop atomic bombs on Hiroshima and Nagasaki has declined significantly since 1945. Scholars and pundits have suggested that this is a sign of the emergence of a “nuclear taboo.”  Such polls, however, do not force respondents to contemplate the tradeoff the U.S. government believed it faced in 1945: choosing between the use of nuclear weapons and a ground invasion of Japan to end the Pacific War. This paper reports on survey experiments recreating that kind of a tradeoff in a hypothetical war with Iran. In order to avoid a ground assault on Tehran that was predicted to kill 20,000 American soldiers, 60% of the U.S. public approved of an atomic attack on an Iranian city that would kill 100,000 civilians and 60% approved of an atomic attack that would kill 2,000,000 civilians. Sixty-seven percent preferred a conventional bombing attack that was estimated to kill 100,000 Iranian civilians. Moreover, the prospect of killing more noncombatants appeared to trigger beliefs in retribution and complicity, as a way of justifying the decisions. Our findings suggest that U.S. public support for the principle of noncombatant immunity is shallow.
