Containment was a foreign policy strategy followed by the United States during the Cold War. First laid out by George F. Kennan in 1947, the policy stated that communism needed to be contained and isolated, or else it would spread to neighboring countries. American foreign policy advisors believed that once one country fell to communism, each surrounding country would fall as well, like a row of dominoes. This view was known as the domino theory. Adherence to the policy of containment and domino theory ultimately led to U.S. intervention in Vietnam as well as in Central America and Grenada.
