During the mid-twentieth century, the United States became increasingly involved in the world affairs. As there were problems in different parts of the world, the United States, as the emerging world power, took its responsibility and sought for ways of tackling the problems. Notable among these is the Vietnam War (1955-1975) that the U.S. involvement was largely felt. Initially, the conflict was internal between South Vietnam and North Vietnam, but it soon shot up into a limited international conflict in which the U.S. supported the government forces of the South. During the war, the roles of Presidents Dwight Eisenhower and John Kennedy were pronounced . President Dwight Eisenhower was the thirty-fourth president of the U.S. who served two terms in office from 1963 to 1961.Under his administration, the U.S. became increasingly involved in global affairs so as to counter the increasing threat to dominance of the Soviet Union. In particular, he used the emerging role of the United States to assist in establishing a non-Conformist state in South Vietnam. His action resulted in catastrophic long-term outcomes that largely increased his effectiveness as the President of the U.S. Eisenhower inherited the foreign policy of his predecessor, Harry S. Truman, in providing financial and military assistance to the South Vietnamese (Solheim, 2008). On November 1, 1995, Eisenhower’s action to give military training to the government of South Vietnam marked the official start of the U.S. involvement in the Vietnamese conflict. On this day, he sanctioned the deployment of the Military Assistance Advisory Group to South Vietnam. Eisenhower’s dynamic leadership style made the Vietnam War to become America’s war. In addition to the military training, he provided the CIA’s (Central Intelligence Agency) Air America services and intelligence assets to assist in the war. Consequently, France, which had tried to re-establish its presence in Vietnam after the Second World War, left the country by April 1956. As much as these actions were effective in defining the role of the U.S. in world affairs, some of his actions inhibited his role as the president. For example, in 1958, he did not take a strong stand when North Vietnam conquered Laos and controlled some sections of the nation. Most Americans believed that he used behind-the-scenes leadership style to exert America’s influence in the world. Eisenhower’s indirect tactics, both at home and abroad, were effective in increasing the engagement of the U.S. in the Vietnam War. Under President John Kennedy, the United States became increasingly engaged in global affairs, particularly in the Vietnam War. On assuming office, he continued with the policy of his predecessor, Eisenhower, in providing more military as well as financial assistance to South Vietnam (Peake, 2008). He was determined not to see the rise of communism in South Vietnam. Therefore, he actively participated in the affairs of the country. Kennedy believed that America should be able to “pay any price, bear any burden, meet any hardship, support any friend…to assure the survival and success of liberty” (Trueman, 2010, para. 3). This is what defined his resolute leadership style in increasing the enga
