The supreme commander of NATO reported directly to the president, not to the Joint Chiefs of Staff, and Norstad was fiercely protective of his authority. He disliked General Thomas Power, the head of the Strategic Air Command, and wanted to preserve NATO’s ability to destroy the Soviet Union without any help from SAC. The thermonuclear warheads atop NATO’s Jupiter missiles were aimed at Soviet cities. With those missiles, and the hundreds of other nuclear weapons under NATO command, Norstad could conceivably fight his own war against the Soviets, on his own terms.
