idea that the threat of nuclear war is enough to prevent an enemy attack
taking a dispute to the edge of conflict to force the enemy to back down

Explanation:

1. The term for the competition to acquire more and deadlier weapons is "arms - race". During the Cold War, the US and the Soviet Union engaged in an intense arms - race to gain military superiority.
2. The belief that a nuclear war would have no winner is known as "mutual assured destruction (MAD)". The logic was that if either side launched a nuclear attack, the other would retaliate, resulting in the destruction of both.
3. The idea that the threat of nuclear war is enough to prevent an enemy attack is also based on the concept of "deterrence". The threat of massive retaliation acts as a deterrent to potential aggression.
4. Taking a dispute to the edge of conflict to force the enemy to back down is called "brinkmanship". It involves pushing a situation to the verge of war to gain an advantage.

Answer:

1. Arms - race
2. Mutual assured destruction (MAD)
