Cuban Missile Crisis Nature Of The Cold War - 1092 Words

COLD WAR ASSIGNMENT (Cuban missile crisis) Nature of the Cold war The cold war was a clash between two superpowers with competing ideologies, or sets of ideas. Although they had been allies against the common enemies of Germany and japan during World War 2, both sides distrusted each other. After the war this distrust evolved into a long term hostility. This era was called the ‘Cold war’ because the two superpowers never directly assaulted each other. This war was very political as it was fought through propaganda, by proxy (the actual battle was fought by too different and not as powerful countries), and threats that could lead to massive conflicts. People have debated whether the Cold War was more a war of ideas and soft power rather than a war dominated by the importance of nuclear weapons and military strength. Nature and causes of the event (Cuban Missile Crisis) The Cuban missile crisis was a very political issue. To discuss its nature, I will first explain the events that led into the happening of the Cuban missile crisis. In 1959, Fidel Castro’s communist government took control of Cuba and the Soviet Union gave the new government economic aid. John F Kennedy became aware of the CIA’s plan to use anti-communist Cubans to overthrow Fidel. The attempted invasion at the Bay of Pigs failed. This event had convinced Castro that the United States had decided to get rid of the communist government, and himself along with it. Castro then turned to the Soviet Union forShow MoreRelatedThe Cuban Missile Crisis During The Cold War1378 Words   |  6 PagesThe Cuban Missile Crisis occurred in 1963 in a setting that was the high point of tension in the Cold War. The most significant background cause of the Cuban Missile Crisis was the underlying cold war ideology of capitalism vs communism. This was dramatically increased by the second ke y cause, a series of events that quickly built tensions between the super powers from 1959 such as the U2 incident, JFK’s response to the Berlin Wall, and the Bay of Pigs incident.
