1946 In March, former British Prime Minister Winston Churchill delivered an "Iron Curtain Speech" in Fulton, USA, which officially kicked off the Cold War. The implementation of Truman Doctrine in the United States from 65438 to 0947 marked the beginning of the Cold War. The establishment of the Warsaw Pact in 1955 marked the formation of a bipolar pattern. 199 1 the disintegration of the Soviet union in showed the failure of socialism under the Soviet model, marked the end of the cold war and the end of the bipolar pattern, which lasted for 44 years. The United States has become the only superpower in the world (the world pattern has become "one superpower and many powers" in the process of world multipolarization).
Both the United States and the Soviet Union are "superpowers" in the world. In order to compete for world hegemony, the two countries and their allies have fought for decades. During this period, although there were serious differences and conflicts, both sides tried their best to avoid the outbreak of a large-scale world war (World War III), and their confrontation was usually carried out by "cold" means such as local proxy war, science and technology and arms race, space competition and diplomatic competition, that is, "mutual containment" without resorting to force, so it was called "Cold War".
The cold war is mainly manifested in the confrontation between two major military groups headed by the United States and the Soviet Union. The struggle between the two superpowers, the United States and the Soviet Union, is the main source of long-term turmoil in the world. The strength of the two military groups is equal, and no one dares to use force easily. Both the United States and the Soviet Union have stored a large number of nuclear warheads and promised each other to destroy them. After two world wars, people all over the world longed for peace and opposed war.
