The Cold War is a stage in the development of relations between the USSR and the United States, which is characterized as confrontation and increased hostility of countries towards each other. This is a huge period in the formation of Soviet-American relations, which lasted almost 50 years.
Historians believe that the official beginning of the Cold War was Churchill's speech in March 1946, in which he invited all Western countries to declare war on communism.
After Churchill's speech, Stalin openly warned US President Truman about the dangers of such statements and the possible consequences.
Expansion of the USSR's influence on Europe and third world countries
Perhaps the emergence of this kind of war was associated with the strengthening of the role of the USSR on the continent and in the world after the victory in World War II. The USSR at that time actively participated in the UN Security Council, on which they had great influence. All countries became eyewitnesses of the strength of the Soviet army, the magnitude of the spirit of the Russian people. The American government saw the growing sympathy of many countries for the Soviet Union, how they bow their heads before the merits of its army. The USSR, in turn, did not trust the United States because of the nuclear threat.
Historians believe that the main root cause of the Cold War was the desire of the United States to crush the growing power of the USSR. Thanks to the expansion of the Soviet Union's sphere of influence, communism spread slowly but surely across Europe. Even in Italy and France, the communist parties began to gain more influence and support. The economic devastation in European countries basically led people to think about the correctness of the positions of communism, about the equal distribution of benefits.
It was this that horrified powerful America: they were the most powerful and richest from World War II, so why are they not asking for help from the United States? Therefore, politicians developed first the Marshal Plan, then the Truman Doctrine, which were supposed to help liberate countries from communist parties and devastation. The struggle for European countries is one of the reasons for waging the Cold War.
Not only was Europe the target of the two powers, their cold war also affected the interests of third world countries that did not openly adhere to any of the countries. The second precondition of the Cold War is the struggle for influence in African countries.
Arms race
The arms race is another reason and then one of the stages of the Cold War. The United States was hatching a plan to drop 300 atomic bombs on the Union - its main weapon. The USSR, which did not want to obey the United States, had its own nuclear weapons by the 1950s. It was then that they left the Americans no chance of using their nuclear force.
In 1985, Mikhail Gorbachev came to power in the USSR, who sought to end the Cold War. Thanks to his actions, the Cold War ended.
In the 60s, the USSR and the USA signed treaties on the refusal to test weapons, on the creation of nuclear-free spaces, etc.
