Deterrence
A strategy of maintaining sufficient military capability and credible willingness to use it so that an adversary is dissuaded from attacking, for fear the costs would outweigh any gains.
Deterrence is the strategy of preventing adversary aggression not by physically blocking it but by convincing the adversary that the consequences of an attack would be unacceptable. Successful deterrence requires two elements: the capability to inflict costs the adversary cannot tolerate, and the perceived willingness to use that capability. If either element is missing, deterrence fails.
Nuclear deterrence is the most prominent form, built on the concept of mutually assured destruction (MAD). The United States maintains a nuclear triad of ICBMs, submarine-launched ballistic missiles, and strategic bombers to ensure that no adversary could destroy America's retaliatory capability in a first strike. This guarantees devastating retaliation, making nuclear aggression suicidal for any attacker.
Conventional deterrence operates on similar principles at lower levels of conflict. Forward-deployed forces like those in South Korea and NATO's eastern members signal commitment to allies and impose immediate costs on any aggressor. The credibility of conventional deterrence depends on visible military presence, demonstrated capability through exercises, and clear political commitment to respond to aggression.
