Answer:
The Cold War was a period of tension and hostility between the United States of America and the Soviet Union from the mid-40s to the late 80s. It began with the end of the Second World War. It was called the Cold War because there was no active war between the two nations, which was probably due to the fear of nuclear escalation. There were many indirect conflicts like the Vietnam and Korea wars. There was the Cuban missile crisis in 1962 which was the closest the world ever came to a nuclear war. An American U2 spy plane took photographs of Soviet intermediate ballistic missiles capable of carrying nuclear payloads. The Soviet Union sent a total of 42 medium range missiles and 24 intermediate range missiles to Cuba. The US threatened to invade Cuba over the issue. Ultimately the Soviets removed the missiles on America’s promise of not invading Cuba
Russian historians blamed Churchill (the British Prime Minister) and Truman (the American president, 1945-1953). They said Truman and Churchill wanted to destroy the USSR, which was just defending itself.
The Traditional View: At first, western writers blamed Russia. They said Stalin was trying to build up a Soviet empire.
The Revisionist View: Later, however, some western historians blamed America. They said Truman had not understood how much Russia had suffered in the Second World War.
The Post-Revisionists: Later still, historians think BOTH sides were to blame – that there were hatreds on both sides.
Most recently, historians agree that the Cold War was primarily a clash of beliefs – Communism versus Capitalism.
The Soviet Union wanted to spread its ideology of communism worldwide, which alarmed the Americans who followed democracy.
The acquisition of atomic weapons by America caused fear in the Soviets.
Both countries feared an attack from each other.
The Soviet Union’s action of taking control over Eastern Europe was a major factor for US suspicions.
The US President had a personal dislike of the Soviet leader Josef Stalin.
America was annoyed by the Soviet Union’s actions in the part of Germany it had occupied.
The Soviets feared that America would use Western Europe as a base to attack it.
The United States and the Soviet Union represented two opposing systems of government. In the United States, the government was elected by free elections unlike the Soviet Union. The people could form political parties to voice their political opinions.
Economic: The United States wanted to encourage free trade throughout the world. The Soviet Union wanted to shield off her own sphere from international commerce
Power rivalry: After the Second World War, with the decline of Europe, power was largely shared between the Soviet Union and the United States. As one wanted ‘to dominate the other, conflicts were inevitable.
Incipient conflict between the Soviet Union and the United States began at the peace-time conferences. Their conflict was intensified after President Truman declared the Truman Doctrine and launched the Marshall Plan in 1947.
Extension of Russian influence in Europe: Even before the end of the war, the Soviet Union had gradually extended her influence in Europe. As the war was drawing to a close in May 1945, the Soviet Union quickly consolidated her control of Eastern Europe. The Red Army began by influencing the post-war elections.
The Cold War was the result of a clash between communism and capitalism, two opposing world-views. Another cause of the build up to the Cold War was the intransigent attitude of both sides. The Soviet Union was extremely concerned about its security after having been invaded twice in the twentieth century. In 1945 America created and used the atomic bomb against Japan and the USSR was determined to create one of its own. Both the USSR and the USA built up huge arsenals of Inter-Continental Ballistic Missiles (ICBMs). The United States tested a hydrogen bomb in 1952 and in November 1955, the USSR developed one too. After that the USA moved its bombers into Europe
