Atomic Tragedy offers a unique perspective on one of the most important events of the twentieth century. As secretary of war during World War II, Henry L. Stimson (1867-1950) oversaw the American nuclear weapons program. In a book about how an experienced, principled man faltered when confronted by the tremendous challenge posed by the intersection of war, diplomacy, and technology, Sean L. Malloy examines Stimson's struggle to reconcile his responsibility for "the most terrible weapon ever known in human history" with his long-standing convictions about war and morality. Ultimately, Stimson's story is one of failure; despite his beliefs, Stimson reluctantly acquiesced in the use of the atomic bomb against heavily populated Japanese cities in August 1945.
