How did the U.S try to stop the spread of communism?

Cold War

The Cold War was a stand-off between the two major superpowers left at the end of World War II: the United States and the Soviet Union. They both tried to further their own ends by influencing nations around the world. The period was marked by conflict and increasing tension that only resolved with the fall of the Berlin Wall and the break up of the Soviet Union in 1991.

Domino Theory

With the fall of North Vietnam to the Communists in 1954, President Dwight Eisenhower explained America's stance in a press conference. As Eisenhower stated when asked about the strategic importance of Indochina: "...you have broader considerations that might follow what you would call the 'falling domino' principle. You have a row of dominoes set up, you knock over the first one, and what will happen to the last one is the certainty that it will go over very quickly...." In other words, the fear was that if Vietnam fell completely to communism, this would spread. This Domino Theory was the central reason for America's continued involvement in Vietnam over the years.

Berlin Airlift

Trying to strengthen their hold on the eastern sector, and perhaps irritated by the Marshall plan and anti-Communist rhetoric, the Soviets cut off ground access to Berlin in June, 1948. President Truman's response was the ordering of what became known as the Berlin Airlift. All available transport aircraft were pressed into service and began operating around the clock to provide Berlin with everything its population needed to survive, from food to fuel to clothing and other necessities of life. The Berlin Airlift was carried on into 1949 when the Soviets eventually backed down and reopened the ground access to Berlin. In all, some 2,200,000 tons of supplies were airlifted into Berlin in 267,000 flights. The airlift, which was opposed by some of the President Truman's advisers, was a diplomatic triumph for the president.

Two fairly simple ways to find your answers, first, grab an encyclopedia.

I know, I know, it is more work than just asking.

Next, type both phrases in Google, again I know it isn't like being spoon fed, but that is life.
