United States law vests the power to control the use of nuclear weapons exclusively in the person of the President or his legal successor. The degree to which this power has been located in a single individual has come into question several times in the history of nuclear weapons, including much more recently. This talk will  will discuss the somewhat convoluted and unintuitive history of how this system was established during the Cold War, the moments at which it has been previously called into question, and discuss some of the policy questions that seem to face us on this matter in the post-Cold War.
