Deterrence is a criminological theory. Deterrence is the idea that someone can be prevented from committing a crime by fear of the potential consequences. Deterrence is the primary theory of punishment in the United States legal system.
It was also a theory in the Cold War, mainly supported by Ronald Reagan and Margaret Thatcher, and on the other side by the Soviets, according to which the deployment of strong weapons was essential to threat the enemy in order to prevent the use of the very weapons. It is also known as Mutual assured destruction and it is opposed to the theory of the unilateral disarmament.
