Introduction Since early fifties the government of the United States began to pay special attention to Vietnam and political situation in this country, because, it was one of the most important regions in the Southeast Asia. In fact, American forces became involved in this war in 1950 when they assisted French troops in fighting against Vietnamese National Army. The main objective of the then administration was to prevent the spread of the Soviet Union influence. However, more active measures were taken only in the sixties. These events should be discussed within the context of the Cold War, and at that moment the relations between the two superpowers were rather tense. During his presidency John Kennedy tried to resolve this conflict and pacify the opposing sides. This policy might have produced results yet after Kennedy assassination, his successor Lyndon Johnson gave preference to the use of military force. In turn, Vietnamese National army received support from the USSR. Many politicians argue that its major goal was to bring democracy and freedom to Vietnamese people and liberate them from the yoke of the Communist Party. Nevertheless, it seems that the major or strategic objective was to win the palm of supremacy in this region. Historians give various explanations concerning the defeat of the US forces. In part, it can be ascribed to the lack of experience. First, many battles were held in jungles and American officers and soldiers were not accustomed to such conditions. The major problem was that face-to-face battle virtually deprived our soldiers of the superiority in number and technology. Moreover, there are some scholars who maintain that the underlying cause of failure was the lack of motivation. In other words, many people did not see the point of fighting in Vietnam. In this regard, it should be mentioned the US allies such the Great Britain and Canada were reluctant to send their troops to this country, and to some extent this contributed to the defeat. There is a widely held opinion among some military officers that this war could have been won if command had continued strategic bombing. According to them, such method would have compelled their rival to yield. Naturally, such argument has some rationale, but such bombings would have caused death to thousands of civilian people. The government abandoned such strategy, because it could tarnish the international reputation of the United States. It is rather difficult to say whether the United States could win this war or not. In theory, the victory was achievable, but it would have taken immense sacrifices, military and civilian. Additionally, this victory would have turned the United States into some kind of an international bully, or even an Evil Empire, seeking to dominate other states. To conclude, the War in Vietnam eloquently demonstrates that military force should only be a last resort. On the whole, this conflict was the failure of both American and Soviet diplomacy. Perhaps, Lyndon Johnson administration should have taken Kennedys approach, aimed at peace negotiations. This might have saved lives of many innocent people.
