At 1:15 p.m. on April 12, 1945, Franklin Roosevelt was sitting for a portrait at his cottage in Warm Springs, Georgia, when his face suddenly fell forward. He raised his left hand to his temple and whispered to his cousin Daisy: "I have a terrific pain in the back of my head." He was dead by 3:35. That evening, Harry Truman, a former farmer and failed haberdasher who had been vice president for eighty-two days and had met with Roosevelt only twice, placed his hand on a Bible and became the thirty-third president of the United States. He had never been briefed on the atomic bomb. Thirteen days later, War Secretary Henry Stimson handed him a three-page memo that began: "Within four months we shall in all probability have completed the most terrible weapon ever known in human history, one bomb of which could destroy a whole city."
Today's guest is James M. Scott, author of Empire of Ashes: Truman, Hirohito, and the Descent into Total War. We discuss how a Hungarian physicist who did his thinking in the bathtub tracked down Einstein by asking a boy on a Long Island street corner to launch the Manhattan Project, why Oak Ridge, Tennessee, became a secret city of 75,000 people who had no idea what they were building, and how the firebombing of Tokyo killed 105,000 people in a single night months before the atomic bombs fell. We look at why Groves wanted to destroy Kyoto for its two thousand temples and Stimson stopped him because he had honeymooned there, how Japan's military leaders refused to surrender even after two atomic bombs and forced an unprecedented intervention by an emperor who had spent the war collecting marine specimens in a palace while his cities burned, and why a group of young officers assassinated the commander of the Imperial Guards and seized the palace on the eve of surrender in a coup that came within hours of succeeding. Scott argues that the historical record supports Truman's decision but lets the last word belong to the survivors, and to a war minister who committed seppuku wearing the white shirt the emperor had personally given him, with a photograph of his dead son folded on top of his dress uniform.
