Henry Kissinger (probably one of the most influential American diplomats of the 20th century) said in his era that "George George has made him like other diplomats in our history I told the diplomatic doctrine of that era "(Kissinger, 1979: 135). But the assessment of this doctrine by Kissinger is worth paying attention to what was successful in his era - not always, even in the Kissinger era. The academic consensus surrounding the ideology that is the classic of Kainan's strategy is relatively lacking, but a small number of people deny that Kenan had a profound influence on the exercise of US foreign policy during the Cold War maybe.
American diplomat George F. Kenan detailed the foundation of this doctrine in the 1946 telegram. As an explanation of the foreign policy of the United States, this term derives from a report submitted to Kennan in 1947 to the US Defense Secretary James Foresta, later used in journal articles. It is a translation of the French codon that described the Western policy towards the Soviet Union in the 1920s. The term confinement is closely related to the policy of President Harry Truman (1945 - 53), including the establishment of the North Atlantic Treaty Organization (NATO) which is a joint defense agreement. President Dwight Eisenhower (1953 - 1961) complied with the competitor's rollback principle, but refused to intervene in the Hungarian uprising in 1956. President Lyndon Johnson (1963 - 1966) constrains the reasons for his policy in Vietnam. President Richard Nixon (1969-74) cooperated with consultant Henry Kissinger to follow a policy called mitigation or mitigation tension
In order to prevent the spread of such communism, the United States pursues containment policies. This containment policy was first proposed by George F. Kenan in the "X" article of 1947. It remains a policy of the United States for the next 25 years. (Columbia Encyclopedia, 2007) The "containment" policy was adopted in a form not engaging in full-scale war with the Communist Soviet Union. Instead, it proposes to limit Communism and the Soviet Union to existing borders. This doctrine led directly to the Vietnam War. "Containment" is based on several arguments. (Chomsky, 2003)
