President John F. Kennedy assumed office on January 20, 1961, following an eight-year career in the Senate. The first Catholic president, Kennedy was also the second youngest to ever serve in the office. In his inaugural address, Kennedy proclaimed “Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe, in order to assure the survival and the success of liberty.” Kennedy came into the presidency determined to reenergize the foreign policy establishment. To that end, he assembled a team of young White House and National Security Council advisers—the so-called “best and the brightest”—which included McGeorge Bundy, Walt Rostow, Ted Sorensen and Arthur Schlesinger, Jr.

Kennedy selected Dean Rusk, a taciturn Southerner and president of the Rockefeller Foundation, as his Secretary of State. Respected within foreign policy circles, Rusk had served in several positions at the Department of State, including Deputy Under Secretary of State and Assistant Secretary of State for East Asian and Pacific Affairs. Rusk believed that the Secretary of State served at the pleasure of the President and thus did not seek control of foreign policy. Kennedy selected Robert S. McNamara, the president of Ford Motor Company, as his Secretary of Defense. Harvard dean McGeorge Bundy served as his National Security Adviser. The Director of the Central Intelligence Agency, Allen W. Dulles, continued in that position, which he had held since 1953.

The Kennedy administration inherited the containment doctrine of the 1940s and 1950s, and maintained the belief that Communism was a threat to the United States. However, the brinksmanship of the Eisenhower era seemed archaic to the Kennedy idealists in their new international vision. Kennedy implemented the “flexible response” defense strategy, one that relied on multiple options for responding to the Soviet Union, discouraged massive retaliation, and encouraged mutual deterrence.
