To what extent did President Eisenhower continue the containment policy of Harry Truman?

Answer 1

The death of Stalin and the development of the hydrogen bomb by both the US and Russia led to a less confrontational approach by Eisenhower, but the policy of containment remained in place until the collapse of the Soviet Union in the late 1980's.

Answer 2

He continued it to a more moderate scale. The Truman Doctrine involved forceful containment, where the host country really has no say in the containment process. The Eisenhower Doctrine was different in that the host country has to call on the US for aid against Communism before they can initiate containment in that country.
