Although both leaders were determined to end the Cold War, it is surprising that it intensified rather than diminished. It became clear that Khrushchev actually meant “peaceful competition” instead of “peaceful coexistence” when he began visiting countries like Burma and Afghanistan to provide them with economic aid if they agreed to support Russia. Following the Western Allied powers' formation of the North Atlantic Treaty Organization (NATO), Khrushchev responded by forming a military alliance of communist countries called the Warsaw Pact. Members of the Warsaw Pact included Albania, Poland, Hungary, Romania, East Germany, and the Soviet Union. The formation of these alliances had been preceded by an arms race in which both of the two major powers sought to overwhelm each other in military terms. equipment. The Soviet Union had tested its first atomic weapon in 1949, and this greatly shocked the Americans as this happened much sooner than expected. Truman had responded by authorizing the development of thermonuclear weapons or hydrogen bombs. They controlled the Asia effect by detonating the H-bomb which was smaller in size than the Hiroshima atomic bomb but 2500 times more powerful than it. The Russians, however, did not want to give up and in 1953 they even managed to produce an H-bomb. Despite Khrushchev's efforts to surpass American military equipment, the Americans have always believed in the existence of a missile gap between them and the Asians. This motivated them to increase their missile forces. The Soviet Union shocked the world when it launched the world's first artificial satellite (Sputnik 1), further threatening Americans who had never thought of it. Khrushchev's idea of ​​criticizing his predecessor... half of paper ......ar of a military attack, he decided to blockade Cuba. Fortunately, Khrushchev sent two telegrams: in the first he proposed to dismantle the nuclear sites if the 'America had agreed not to invade Cuba and in the second he asked for the dismantling of American sites in Turkey. In contrast, an American U2 plane was shot down in Türkiye around that time, but JF Kennedy decided to ignore the incident following the turn of events at the time. Peace crept in when President Kennedy finally publicly agreed not to invade Cuba and proceeded to dismantle the sites in Türkiye. Although both leaders had a crisis, they agreed to set up a hotline to discuss the issue, and in 1963 they agreed to sign a treaty banning the testing and use of nuclear weapons. The Cuban crisis ended up becoming very significant while from then on the Cold War began to become insignificant.
