In deterrence theory, what role does showcasing military capability play?

Showcasing military capability plays a crucial role in deterrence theory primarily by serving to intimidate potential adversaries. The essence of deterrence is to prevent aggression by demonstrating that a state possesses the means and readiness to respond forcefully to threats. By visibly exhibiting military strength, such as through military exercises, weapon displays, or advancements in technology, a nation signals to potential aggressors that there would be severe consequences for hostile actions. This display aims to create a perception of strength and resolve, ultimately discouraging adversaries from contemplating an attack or hostile actions due to the perceived risks involved. The underlying principle is that the cost of acting aggressively outweighs any potential benefit, thereby achieving a state of stability and peace through a calculated display of power.
