Dean Rusk -- the sole cabinet member addressed by President John F. Kennedy as "Mr. Secretary" -- was the second-longest-serving secretary of state: his service spanned the Kennedy and Lyndon B. Johnson administrations, from 1961 to 1969. His interview conducted for War and Peace in the Nuclear Age illustrates Rusk and Kennedy's close relationship during the Cuban missile crisis and conveys the President's emotions and approach to decision-making as events unfolded. While Rusk was part of the Executive Committee inner circle during the missile crisis, he was also a separate entity: he reserved his recommendation "until the President and I heard from all of these working groups." Throughout the two-week crisis, Rusk avidly pursued a diplomatic resolution, helped build consensus, and facilitated out-of-channel communications. Beyond the missile crisis, Rusk talks about European fears that the United States' commitment to the North Atlantic Treaty Organization (NATO) would be weakened by the "flexible response" strategy.
