Why was the possibility of superpower conflict a frightening one?

The possibility of superpower conflict was frightening due to the immense destructive capacity of nuclear weapons possessed by the United States and the Soviet Union during the Cold War. A direct confrontation could lead to a catastrophic global war, resulting in unprecedented loss of life and widespread devastation. Additionally, the ideological divide between capitalism and communism heightened tensions, making diplomatic resolutions seem increasingly difficult. This environment of fear and uncertainty contributed to a pervasive anxiety about the future and the safety of humanity.
