President John F. Kennedy expanded U.S. special forces in 1961 as part of a strategic shift toward flexible response, a policy designed to move the United States away from an over-reliance on the doctrine of massive retaliation.1

Kennedy and his advisers viewed the rise of communist-led insurgencies in Asia, Africa, and Latin America as a direct challenge to global stability. They identified these movements as "wars of national liberation," which utilized guerrilla warfare to subvert and overthrow emerging governments. By increasing the training and capabilities of special forces, Kennedy aimed to provide the United States with the specialized tools necessary to conduct counterinsurgency operations. This expansion was intended to demonstrate American resolve in meeting the challenge of communist expansion in the Third World and to ensure the United States could effectively support its allies against unconventional threats.21
