The Cold War started to develop after the Second World War when the USA and the USSR no longer had a common goal of Hitler’s Nazism. As soon as Cold War was instigated, the differences in ideology and other factors worsened the relationship between the USA and the USSR. This meant that many events such as Cuban Missile Crisis and arms race nearly led to a hot war. As Cold War progressed until the collapse of the Soviet Union, Cold War had significant impact on American , Cold War instigated strong anti-communism within the USA. The hatred towards Communism was so great that it eventually led to McCarthyism. During McCarthyism, Americans were obsessed with the process of identifying the Communists and removing those Communists from American society. The strength of this obsession increased greatly that Americans started to forget the fact that the US constitution guaranteed all Americans freedom to believe what they wanted to believe. The purpose of organisations such as the Federal Bureau of Investigation and the House Un-American Activities became the ‘removal of Communists’ and laws such as the Communist Control Act were passed to facilitate the process of identifying, capturing and removing Communists. The McCarran Act was also introduced, which forced all Communist organisations to be registered within the US government and banned Communists carrying US passports and working in defence industries. Inevitably, many were questioned without having done anything wrong, many lost their jobs and some even lost their lives like the Rosenbergs, who were blamed for having passed secret information about atomic bombs to the Soviet Union. This red scare continued to dominate the American society until late , Cold War made many Americans to live in fear of danger of war. This fear of war was instigated by the arms race. One example is Cuban missile crisis, which caused high tension within the USA as the missiles in Cuba could reach the USA at any time. Until the U-2 planes found the missiles in Cuba, the fear was not significant as people knew that the missiles in the USSR could not cover such long distance to reach the USA. However, the missiles in Cuba threatened the USA’s security to a significant extent that many Americans had to live in fear. Although the attitude of Mutual Assured Destruction (MAD) was existent, the missiles in such proximity alarmed many Americans at that time. Apart from Cuban missile crisis, Americans lived in constant fear as the Cold War could turn into a hot war at any , Cold War had an impact on American people economically. The impact was caused mainly by the increase in the amount of taxes. The United States used to adopt isolationism previously, meaning that the USA did not intervene in any other foreign matters to only concentrate on the domestic issues. As soon as the USA decided to intervene in foreign matters, Americans had to pay more taxes to support the USA’s actions. These actions, including the arms race and other wars, required massive amount of capital. For instance, the Vietnam War was one of the factors that used up massive amount of capital. The Vietnam War was very different from any other wars because it was a guerrilla war between Vietcongs. The Vietcongs had successfully planned the strategies to kill many Americans without having America’s latest technology such as tanks and airplanes. As the war developed, it was estimated that it costed Americans $400,000 to kill one Viet conclude, although the Cold War never actually led to a hot war between two major powers, the USA and the USSR, it caused massive impact upon the world, including American society. The main impacts include anti-Communism, fear of war and economic damage. Of all the impacts, I believe that anti-communism is the one that caused everlasting impact on American society. The fear of war and the economical impact had short term effect while the hatred towards communism still exists within American society.
