Atomic bombings of Hiroshima and Nagasaki
By August 1945, the Allies' Manhattan Project had produced two types of atomic bombs, and the 509th Composite Group of the United States Army Air Forces (USAAF) was equipped with the specialized Silverplate version of the Boeing B-29 Superfortress that could deliver them from Tinian in the Mariana Islands. Orders for atomic bombs to be used on four Japanese cities were issued on July 25. On August 6, one of the modified B-29s dropped a uranium gun-type bomb codenamed "Little Boy" on Hiroshima. Three days later, on August 9, a plutonium implosion-type bomb codenamed "Fat Man" was dropped by another B-29 on Nagasaki. The bombs immediately devastated their targets. Over the next two to four months, the acute effects of the atomic bombings killed 90,000–146,000 people in Hiroshima and 39,000–80,000 people in Nagasaki; roughly half of the deaths in each city occurred on the first day. Large numbers of people continued to die from the effects of burns, radiation sickness, and other injuries, compounded by illness and malnutrition, for many months afterward. In both cities, most of the dead were civilians, although Hiroshima had a sizable military garrison.
Debate over the atomic bombings of Hiroshima and Nagasaki
In 1959, Mitsuo Fuchida, the pilot who led the first wave in the surprise attack on Pearl Harbor, met with General Paul Tibbets, who piloted the "Enola Gay" that dropped the atomic bomb on Hiroshima, and told him that:
Some historians see ancient Japanese warrior traditions as a major factor in the resistance in the Japanese military to the idea of surrender. According to one Air Force account,
Japanese militarism was aggravated by the Great Depression, and had resulted in countless assassinations of reformers attempting to check military power, among them Takahashi Korekiyo, Saitō Makoto, and Inukai Tsuyoshi. This created an environment in which opposition to war was a much riskier endeavor.
