Answer:
There were more than one. We have the Truman Doctrine and the Marshall Plan.
Step-by-step explanation:
The term Truman Doctrine refers to a set of practices of the United States government on a world scale, at the time of the Cold War, which sought to contain the advance of communism along the so-called "weak links" of the capitalist system.
The Marshall Plan, a deepening of the Truman Doctrine, officially known as the European Recovery Program, was the main plan of the United States for the reconstruction of the allied countries of Europe in the years following World War II.
