The Cold War was a very important event that changed the history of not only the United States and the Soviet Union, the two greatest superpowers in the conflict, but of the entire world. The conflict between the two greatest superpowers could have led to a potential threat to all countries which had been crucial to prevent. The Nixon administration pursued a very active foreign policy that was the basis for marking the end of the Cold War. During the Nixon administration one of the biggest political scandals in the history of the United States known as the Watergate Affair took place. Watergate is a complex network of political scandals that occurred from 1972 to 1974 during the Nixon administration that ultimately resulted in the president's resignation. The main research question is: How did the Watergate affair affect the development of the Cold War? The research premise is that the Nixon administration had an immense influence on the emergence of the détente policy, and thus the knowledge of the Watergate affair accelerated said détente policy in the Cold War. The research goal, in addition to describing the Watergate affair, is to show the influence of the Nixon presidency in the context of the external political influence of the Cold War.
