A. Plan of the Investigation This historical investigation will discuss about the following question: To what extent was the U.S. successful in containing communism in Vietnam during the Cold War while still maintaining order in the US? The investigation will examine: Foreign and Containment Policies, The Domino Theory, The Vietnam War and The Anti-War Movement. Government documents, speeches, academic journals, and newspaper articles are mainly used to investigate the U.S. involvement and whether or not they were successful in the containment of communism. In this investigation two primary sources were utilized to evaluate their origins, purposes, values and limitations. The first source will be "The Truman Doctrine," by Harry S. Truman. The second will be "The Row of Dominoes" speech by Dwight Eisenhower. B. Summary of Evidence - Foreign Policy and Containment Policies The Truman Doctrine The spread of communism from Greece to Turkey was the main fear of the U.S. Government after the Greek Civil War.

Vietnam used to be a French colony but after World War 2, they declared themselves independent with the outcome of the north being communist and the south being democratic. The Soviet Union sided with the north because they were communist and the United States ended up siding with the south because they
