Charles Sweeney
Poor bombing visibility and an increasingly critical fuel shortage eventually forced "Bockscar" to divert from Kokura and attack the secondary target, Nagasaki. As they approached Nagasaki, the heart of the city's downtown was covered by dense cloud, and Sweeney and the plane's weaponeer, Commander Ashworth, initially decided to bomb Nagasaki using radar. However, a small opening in the clouds allowed "Bockscar's" bombardier to verify the target as Nagasaki. As the crew had been ordered to drop the bomb visually if possible, Sweeney decided to proceed with a visual bomb run. "Bockscar" then dropped "Fat Man", with a blast yield equivalent to 21 kilotons of TNT. It exploded 43 seconds later at above the ground, at least northwest of the planned aim point. The failure to drop "Fat Man" at the precise bomb aim point caused the atomic blast to be confined to the Urakami Valley. As a consequence, a major portion of the city was protected by the intervening hills, and only 60% of Nagasaki was destroyed. The bombing also severed the Mitsubishi arms production extensively and killed an estimated 35,000-40,000 people outright, including 23,200-28,200 Japanese industrial workers, 2,000 Korean slave laborers, and 150 Japanese soldiers.
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.
