The correct answer is Containment and Rollback.
The phases in which military force most likely used U.S. Security policies after World War II were Containment and Rollback.
For the United States, Rollback is the most aggressive foreign policy. It meant that the government could overthrow communist regimes in some parts of the world in order to replace them with a better system for the U.S, interests. Containment in a “not so aggressive” policy. It meant that the government of the United States tried only to contain the spread of Communism in areas of the world. There was another phase called “Detente”, in which the U.S. government would have a cooperative attitude with the Soviet Union.
