Which term denotes the policy of dissuading aggression by threatening credible punishment?

• A. Containment
• B. Deterrence
• C. Détente
• D. Escalation

Answer: (B)

Deterrence is the policy of dissuading aggression by threatening credible punishment. The idea rests on the belief that an attacker will weigh the expected costs of an action against its potential gains, and if the costs are perceived as unacceptable, they will refrain from acting. The word “credible” is crucial—the punishment must be believable, supported by real capability and a willingness to apply it if needed, or the threat loses its deterrent value.

This concept became central in Cold War strategy, where nations relied on the prospect of substantial retaliation (for example, a secure second-strike capability) to prevent others from launching first strikes. Understanding deterrence helps explain why states sometimes act cautiously even during tense moments: the fear of unacceptable consequences keeps the peace.

Other terms describe different approaches. Containment aims to prevent the spread of influence or expansion through alliances and pressure rather than a direct threat of punishment. Détente refers to easing tensions and improving relations rather than coercive threats. Escalation involves increasing the severity of responses to provocation, rather than deterring beforehand.
