Brinkmanship is a strategic tactic in which you take a dangerous dispute or conflict and escalate it to the closest possible point to disaster (usually war or some other military conflict), only to back off at the last second. It is often used to attempt to steer negotiations in one's preferred direction. It entered widespread use in most Western countries during the Cold War, especially with reference to the Cuban missile crisis.
