After the Second World War ended in 1945, there started a phase of Cold War. The President, Harry Truman came up with Truman doctrine. The Truman Doctrine of containment was a policy adopted by United States in order to control the expansion of Soviet Union. According to this policy, U.S. was there to support any country, with both military and economy whose stability was threatened by communism. President Harry Truman said, “It must be the policy of the United States to support free people who are resisting attempted subjugation by armed minorities or by outside pressures.” In 1947, US signed a defense treaty with Latin-America, called the Inter-American Treaty of Reciprocal Assistance (also called Rio Treaty), according to which an attack against one was considered as an attack against all. It aimed at maintaining peace and security in the continent, in order to strengthen the relations of friendship and good neighborliness Furthermore, in 1948, the Organization of American States (OAS) was created during the ninth Conference of American States, which aimed at achieving an order of peace and justice in the continent, promoting democracy with non-interference of other states, settling disputes among the countries, seeking solutions for the political, economical and judicial problems that may arise between them, establishing cooperation among its member states and so on (Friedman & M.P., 2003).
The result of all these steps can be observed in the case of Guatemala. Since 1930, the dictator General, Jorge Ubico, with the support of the United States, ruled over Guatemala. His period of rule is considered as one of the toughest situation that the Latin America has ever gone through. In return of the support of his rule, United States got thousands of hectares of land for the American United Fruit Company (UFCO) as well as bases for U.S. military in Guatemala.
