COLD War and the Arms Race

Cold War and Army Competition The essence of international security has undergone an irreversible change when President Truman approved the use of two nuclear weapons against Japan in Japan in Hiroshima and Nagasaki for the conclusion of World War II. At that time, the United States has been told that it had the exclusive right of the atomic bomb. Shortly thereafter, the Soviet Union started researching nuclear weapons. In 1949, it exploded the first atomic bomb, and the tension between the two countries began to get hot.

After the war, it experienced a long Cold War (1945-1991). The momentum of technological development in the two major wars led to innovation in the Cold War era. Nuclear weapons competition may be the only regrettable technical use during the Cold War. Other innovations during this period offered a very good service to humans. The most important invention of the Cold War was transistor (1945), which led to integrated circuits. Today's world is mainly affected by semiconductor applications. Transistors enable computers. One of the first computers built was ENIAC (1946), using 19,000 vacuum tubes consuming 150 kilowatts of power, and rarely operated continuously for more than an hour without maintenance. Transistors revolutionized the reliability, size, and ease of use of electronic devices. The value of the computer was immediately recognized, and in 1976 the first super computer CRAY - 1 was used.

Along with the beginning of the Cold War arms race in the 1950s, the apocalyptic war between the US and the Soviet Union became a reality. During the Cold War (1947 - 1991), several military incidents were said to be very close to causing the Third World War. The Korean War was a war between the Communist alliance including the two Union, North Korea, China, and the Soviet Union, who tried to rule the Korean Peninsula, and the capitalist alliance including South Korea, the United States, and the United Nations. Many people believe that this conflict may soon expand to a full-blown war between the three countries, the US, the Soviet Union and China. Mr. Bill Downs, a local correspondent at CBS wrote in 1951, "In my opinion, the answer is as follows: Yes, South Korea is the beginning of World War III, winning Korea's victory
