Question

which of the following is the best definition of the term nuclear deterrence?
the belief that a nuclear war would have no winner
the idea that no nuclear weapon was as strong as armed forces
the idea that the threat of nuclear war was enough to stop an attack
the competition to acquire more and deadlier weapons

Explanation:

Nuclear deterrence is based on the concept that the threat of a nuclear response (the existence of nuclear weapons and the willingness to use them) can prevent an adversary from taking hostile actions. The first option is more about the nature of nuclear war itself rather than deterrence. The second option is incorrect as nuclear weapons are extremely powerful. The fourth option describes an arms - race rather than deterrence. The third option correctly captures the essence of nuclear deterrence - using the threat of nuclear war to prevent an attack.

Answer:

the idea that the threat of nuclear war was enough to stop an attack
