How does deterrence differ from defense?

The concept of deterrence fundamentally revolves around preventing an adversary from taking aggressive actions by instilling the belief that the costs of such actions would outweigh any potential benefits. This approach seeks to prevent conflict entirely by creating a credible threat of retaliation or consequence, thereby discouraging any would-be aggressors from initiating hostilities.

The choice emphasizing that deterrence seeks to prevent conflict altogether accurately captures this strategic intent. The aim is not to engage in battles or confrontations but to maintain peace through the fear of repercussions. This psychological and strategic framework is essential in international relations and military strategy, distinguishing it from defense, which is focused more on protecting assets or responding to an attack.

In contrast, defense typically involves the active protection of one's territory and interests once an attack has already occurred, thereby requiring different strategies, resources, and readiness compared to the preventive nature of deterrence.
