Which of the following best describes “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

Nuclear deterrence is a preventive military strategy used during the Cold war. It aims to discourage the enemy by the destructive power of Nuclear Weapons. For example, if a country has a nuclear weapon and shows how destructive it can be, its enemies will deter and avoid attacks because they will want to avoid being hit  afterwards by the nuclear weapon. Thus, the right option is "the idea that the threat of nuclear war was enough to stop an attack".
