Deterrence Theory is a concept in political science and military strategy that suggests the prevention of unwanted actions, such as aggression or crime, by instilling fear of consequences. It operates on the premise that if potential offenders believe the costs of their actions outweigh the benefits, they are less likely to engage in those actions. This theory is often applied in the context of nuclear strategy, where the threat of retaliation is intended to deter attacks. It also influences criminal justice policies, where harsher penalties aim to discourage criminal behavior by making the risks more apparent to potential offenders.
