Two attempts the USA made with efforts to stop the spread of communism were the Marshall Plan and the Truman Doctrine. The Marshall Plan was created to help out Europe economically with aims to recreate the European economy before the second world war. The second attempt made to stop the spread of communism was the Truman Doctrine, implemented by the president of the time, Harry Truman. It essentially was the promise and idea to help out any democratic nation, politically, economically, and militarily. This assistance from the US surely helped cease the further spread of communism in Europe from 1945-1950. These plans were in motion for about 4 years and they did what they were created to do.
“We are going to continue to fight communism. Now I am going to tell you how we are not going to fight communism. We are not going to transform our fine FBI into a Gestapo secret police. That is what some people would like to do. We are not going to try to control what our people read and say and think. We are not going to turn the United States into a right-wing totalitarian country in order to deal with a left-wing totalitarian threat.” - Harry Truman
