Answer:
To produce mutual defense against the Soviet Union, is the right answer.
Explanation:
The requirement for the North Atlantic Treaty Organization (NATO) emerged from the ongoing tension between the Soviet Union and partnered countries in North America and Western Europe. In 1948, Soviet-controlled East Germany forced a bar on West Berlin, which was constrained by the U.S., United Kingdom, and France. Simultaneously, communist uprisings began in Greece, Turkey, and Czechoslovakia, accepted to be prodded by the USSR.
Tragically, most nations in Western Europe felt that they couldn't both guard themselves against the amazing USSR and effectively battle the communist danger emerging in different nations. In 1949, the United States, Canada, and other Western European nations marked the North Atlantic Treaty that expresses an attack on one-part country ought to be viewed as an assault (attack) on all part countries. Therefore, the main reason why NATO was formed is to produce corporate defense against the Soviet Union.
