Colonel Stimson was worried. A week earlier, a few days after the atomic bomb had exploded over Hiroshima, he had a small heart attack. With intimations of mortality, the weary secretary of war, who was nearly 78, had decided to resign. His deepest concern, however, may not have been his health but the future of the atom.
