Nuclear brinkmanship

Nuclear brinkmanship uses threats and deliberate risk-taking to pressure an opponent during a nuclear confrontation, often by creating a danger that neither side can fully control.

Deterrence theory: The theory that threats of costly retaliation can prevent an adversary from taking an unwanted action. Brinkmanship strengthens deterrence by making the risk of nuclear escalation part of the threat.
Cuban Missile Crisis: The 1962 confrontation between the United States and the Soviet Union over Soviet missiles in Cuba. The crisis became a defining case of nuclear threats and controlled escalation.
Compellence: A strategy that uses threats or limited force to make an opponent change an existing policy or action. Brinkmanship can serve compellence, but compellence does not require nuclear risk-taking.
Nuclear war: Armed conflict involving the detonation of nuclear weapons by one or more states. The worst-case outcome that brinkmanship tries to threaten without actually causing.
Escalation ladder: A model of progressively more intense steps in a conflict, from limited actions to nuclear war. Each step can signal resolve while increasing the danger that a confrontation will climb further.
Able Archer 83: A 1983 NATO command-post exercise that Soviet leaders may have misread as preparation for a real attack. The episode shows how military signaling can be mistaken for an imminent nuclear strike.
Deterrence: A strategy that prevents an opponent from acting by threatening unacceptable costs. Deterrence seeks to preserve the status quo; brinkmanship may force a change through escalation risk.
Accidental nuclear war: A nuclear war begun unintentionally through error, false warning, or unauthorized action. The risk of accident rises when crises compress decision time and intensify alert postures.
Mutual assured destruction: A strategic condition in which nuclear retaliation would destroy both the attacker and the defender. The prospect of reciprocal catastrophe gives nuclear threats their coercive force.
Berlin Crisis of 1961: A Cold War confrontation over Berlin that included a standoff between American and Soviet tanks. Military deployments and resolve signaling created pressure without direct combat.
