What was the decades long conflict between the US and the soviet uninon referred to?

The decades-long conflict between the United States and the Soviet Union is referred to as the "Cold War." This period, spanning roughly from the late 1940s to the early 1990s, was characterized by political tension, military rivalry, and ideological differences between the capitalist West and the communist East. Rather than direct military confrontation, the conflict involved proxy wars, nuclear arms races, and intense espionage. It ultimately ended with the dissolution of the Soviet Union in 1991.
