How did George Kenman's containment doctrine change during the Truman Eisenhower's and Kennedy administration?

Answer 1

George Kennan's containment doctrine evolved through the administrations of Truman, Eisenhower, and Kennedy. Under Truman, containment focused on military and economic aid to countries resisting communism, exemplified by the Marshall Plan. Eisenhower introduced the concept of "massive retaliation," emphasizing nuclear deterrence and the use of covert operations to counteract communist influence. By the Kennedy administration, containment adapted to include flexible responses, promoting a range of military and non-military strategies to address diverse global challenges, reflecting a more nuanced approach to Cold War tensions.
