Zusammenfassung	Deterrence modeling uses game theory to analyze when a defender can dissuade a challenger from aggression by threatening unacceptable costs. Classical deterrence theory, rooted in Schelling's work and Cold War nuclear strategy, was reformulated by Frank Zagare and D. Marc Kilgour in Perfect Deterrence (2000) into a family of incomplete-information games. These models make precise the two requirements a deterrent threat must meet — capability (the means to inflict the cost) and credibility (a genuine willingness to carry it out) — and identify the equilibrium conditions under which deterrence succeeds, fails, or collapses into conflict.	A crisis bargaining game is a formal, usually extensive-form model in which two states sequentially choose to challenge, escalate, stand firm, or back down during an international dispute, and the analyst solves for the equilibrium pattern of escalation and concession. Building on Schelling's strategy of conflict and given an influential treatment in Fearon's (1994) model of escalation as a war of attrition, these games make explicit how incomplete information about each side's resolve, and the costs each pays for backing down, shape whether a crisis ends in mutual accommodation, capitulation, or war.
