Moreover, Defense Secretary James Schlesinger recalled years later that in the final days of the Nixon presidency he had issued an unprecedented set of orders: If the president gave any nuclear launch order, military commanders should check with either him or Secretary of State Henry Kissinger before executing them.

Nixon himself had stoked official fears during a meeting with congressmen during which he reportedly said, “I can go in my office and pick up a telephone, and in 25 minutes, millions of people will be dead.” Senator Alan Cranston had phoned Schlesinger, warning about “the need for keeping a berserk president from plunging us into a holocaust.”
