For more than a half century scholars and nonscholars alike have debated the ethics of dropping the atomic bomb, but rarely have they studied the American plan to invade Japan, the alternative to using the bomb to end the Second World War. Widely held beliefs about the strength of Japanese forces and the projected loss of American lives have been invoked to justify the decision to drop the bomb. John Ray Skates, however, argues that the invasion plan, code named Operation Downfall, until now has not been sufficiently studied to allow such a justification. In The Invasion of Japan he remedies that shortcoming and disputes many myths that have grown up around the plan.
