During the Cold War, a battle between American capitalism and Russian communism, the United States found themselves fighting in Vietnam, but if the battle was against Russia, then why was Vietnam involved? The reason for this, simply stated, is because Vietnam was supporting the Soviet Union, and America needed to put a stop to it. At this time, Vietnam was divided in two parts: North Vietnam(Democratic Republic of Vietnam) and South Vietnam(Republic of Vietnam). North Vietnam was supporting the USSR, and South Vietnam was being aided by the United States to defeat North Vietnam. The Vietnam War refers to specifically the battle between the USA and North Vietnam. Once it was established that a war between these two countries had begun, other surrounding nations took their stances and supported their preferred side. As was already instituted, North Vietnam was aided by the USSR, but the People’s Republic of China also joined the fight in favor of the communist takeover. South Vietnam, however, was supported by many more nations. Those being the USA, Korea, Australia, New Zealand, Thailand, and the Philippines.
