Why was President Kennedy's Cold War foreign policy called New Frontier?

Kennedy's close advisers believed that Eisenhower's foreign policy establishment was stultified, slow moving, overly reliant on brinksmanship and massive retaliation, and complacent. Their fear was that after eight years, the State Department would be unable to implement their new international vision. The new President was determined to control foreign policy through a young and energetic White House and NSC staffers who would make their own informal contacts within the foreign affairs bureaucracy. Furthermore, Kennedy thought that Eisenhower and Secretaries Dulles and Herter had all but ceded the newly emerging states in Latin America, Asia, and Africa to the communists.
