What were the three major elements of the US foreign policy under Truman and Eisenhower?

The main elements of Dwight D. Eisenhower were: (1) maintaining the vitality of the U.S. economy while still building sufficient strength to prosecute the Cold War; (2) relying on nuclear weapons to deter Communist aggression or, if necessary, to fight a war; (3) using the Central Intelligence Agency (CIA) to carry out secret or covert actions against governments or leaders "directly or indirectly responsive to Soviet control"

Sorry I could only come up with Eisenhower, I hope it is helpful
