When private bands of fanatics commit atrocities we call them "terrorists," which they are, and have no trouble dismissing their reasons. But when governments do the same, and on a much larger scale, the word "terrorism" is not used, and we consider it a sign of our democracy that the acts become subject to debate. If the word "terrorism" has a useful meaning (and I believe it does, because it marks off an act as intolerable, since it involves the indiscriminate use of violence against human beings for some political purpose), then it applies exactly to the bombings of Hiroshima and Nagasaki.
