Deterrence works by increasing the enemy's fear of what?

• A. Failure
• B. Success
• C. Loss of Legitimacy
• D. Strategic Surprise

Answer: (A)

Deterrence is about shaping the adversary’s risk calculus by threatening costly outcomes that discourage aggression. The best way to deter is to make the attacker fear a failure to achieve their objectives, because if they believe their plan will fail or provoke overwhelming costs, they’ll think twice before acting. This focus on the risk of not attaining strategic aims—and paying a steep price for it—drives the decision to refrain from aggression. The other potential fears don’t align as directly with the deterrent effect. Fear of success would imply the attacker is motivated to act, which is the opposite of deterrence. Loss of legitimacy involves internal political costs and legitimacy concerns rather than the immediate calculation of whether an attack will work, making it a less direct deterrent lever. Strategic surprise is a factor that can influence outcomes, but deterrence itself rests on preventing action by making failure and its consequences seem too costly.
