"Midway through the Cold War, American leaders began to worry that a rogue US officer might launch a small, unauthorized strike, prompting massive retaliation. So in 1962, Robert McNamara ordered every nuclear weapon locked with numerical codes. Irritated by the restriction, Strategic Air Command set all the codes to strings of zeros. The Defense Department didn't learn of the subterfuge until 1977."
