What concept suggests that a large arsenal of weapons can deter an enemy from launching an attack?

The concept that a large arsenal of weapons can deter an enemy from launching an attack is known as deterrence. This principle is based on the idea that the possession of significant military capabilities, particularly nuclear weapons, can discourage adversaries from taking aggressive actions. The rationale is that the potential consequences of a retaliatory strike, including devastating loss of life and destruction, would outweigh any potential gains from an initial attack. This creates a stable environment where both sides recognize the high stakes involved, hence reducing the likelihood of conflict.

In the context of international relations and military strategy, deterrence plays a crucial role during conflicts, influencing decisions made by states regarding military engagement. By maintaining or showcasing a formidable military presence, a nation aims to ensure its security through the threat of overwhelming retaliation, effectively preventing hostile actions from other states. Understanding deterrence helps in analyzing historical and contemporary military strategies and the dynamics of power between nations.
