A Beaten Country
Apart from the moral questions involved, were the atomic bombings militarily necessary? By any rational yardstick, they were not. Japan already had been defeated militarily by June 1945. Almost nothing was left of the once mighty Imperial Navy, and Japan's air force had been all but totally destroyed. Against only token opposition, American war planes ranged at will over the country, and US bombers rained down devastation on her cities, steadily reducing them to rubble.
What was left of Japan's factories and workshops struggled fitfully to turn out weapons and other goods from inadequate raw materials. (Oil supplies had not been available since April.) By July about a quarter of all the houses in Japan had been destroyed, and her transportation system was near collapse. Food had become so scarce that most Japanese were subsisting on a sub-starvation diet.
On the night of March 9-10, 1945, a wave of 300 American bombers struck Tokyo, killing 100,000 people. Dropping nearly 1,700 tons of bombs, the war planes ravaged much of the capital city, completely burning out 16 square miles and destroying a quarter of a million structures. A million residents were left homeless.
On May 23, eleven weeks later, came the greatest air raid of the Pacific War, when 520 giant B-29 "Superfortress" bombers unleashed 4,500 tons of incendiary bombs on the heart of the already battered Japanese capital. Generating gale-force winds, the exploding incendiaries obliterated Tokyo's commercial center and railway yards, and consumed the Ginza entertainment district. Two days later, on May 25, a second strike of 502 "Superfortress" planes roared low over Tokyo, raining down some 4,000 tons of explosives. Together these two B-29 raids destroyed 56 square miles of the Japanese capital.
Even before the Hiroshima attack, American air force General Curtis LeMay boasted that American bombers were "driving them [Japanese] back to the stone age." Henry H. ("Hap") Arnold, commanding General of the Army air forces, declared in his 1949 memoirs: "It always appeared to us, atomic bomb or no atomic bomb, the Japanese were already on the verge of collapse." This was confirmed by former Japanese prime minister Fumimaro Konoye, who said: "Fundamentally, the thing that brought about the determination to make peace was the prolonged bombing by the B-29s."
