In bargaining, the power to constrain an adversary often depends on the power to bind oneself: a negotiator who visibly and irreversibly commits to a position forces the other side to make the final concession or accept breakdown. Burning bridges, delegating to an agent with no authority to yield, or staking public reputation on a demand converts inflexibility into leverage, so limiting your own options can be rational.
When parties must coordinate without communicating, they converge on the option that stands out as salient, unique, or conventional: a 'focal point' whose prominence lets each predict what the other will predict. In Schelling's classroom experiments, most people told to meet a stranger in New York with no prior arrangement chose Grand Central Station at noon, showing that shared cultural and perceptual cues, not payoffs, often decide the outcome.
Schelling points to limited wars such as Korea, where fighting was held to boundaries that neither side had formally negotiated, including geographic lines like rivers and the distinction between using and not using nuclear weapons. These limits held because they were qualitative, obvious, and easy to recognize, while a limit defined by degree, such as 'a few small bombs,' offers no natural stopping place once crossed.
A threat to do something self-damaging, such as launch a nuclear war, is not credible if its execution is fully under deliberate control. Brinkmanship makes such a threat believable by manipulating a shared risk of things spiraling out of control, where neither side can be sure of stopping the process, so the threat's force comes from an uncontrollable probability of disaster rather than a decision to carry it out.
Most real conflicts are not zero-sum contests but mixed-motive games in which adversaries share an interest in avoiding mutually destructive outcomes while competing over the division of gains. Viewing war, strikes, or extortion this way shifts attention from winning to influencing the other side's expectations and choices, so that deterrence, threats, and promises become forms of communication and bargaining.
