In 1957 Kissinger published ''Nuclear Weapons and Foreign Policy,'' which proposed a flexible defense posture, including provision for "limited warfare" and the strategic employment of nuclear weapons as an alternative to the doctrine of "massive retaliation" against direct foreign aggression, which dominated military thinking during the mid-1950s. The book brought Kissinger to national attention, and he became an mid-level advisor on security questions under presidents [[Dwight D. Eisenhower]], [[John F. Kennedy]], and [[Lyndon B. Johnson]]; he was foreign policy advisor in [[Nelson Rockefeller]]'s 1968 quest for the Republican party nomination, but Nixon won the nomination and Kissinger switched to the winner.
