边缘政策
边缘政策：通过创造一种印象来寻求利益的国际政治实践，即一个人情愿并能够把高度危险的局势推到极限而不是退避
Brinkmanship is the practice of pushing a dangerous situation to the verge of disaster in order to achieve the most advantageous outcome. It occurs in international politics, foreign policy and (in contemporary settings) in military strategy involving the threatened use of nuclear weapons.
This maneuver of pushing a situation to the brink succeeds by forcing the opposition to back down and make concessions. This might be achieved through diplomatic maneuvers by creating the impression that one is willing to use extreme methods rather than concede. During the Cold War, the threat of nuclear force was often used as such an escalating measure.
