"The ability to get to the verge without getting into the war is the necessary art. If you cannot master it, you inevitably get into war. If you try to run away from it, if you are scared to go to the brink, you are lost."The quote was widely criticized by the Eisenhower Administration's opponents, and the first attested use of brinkmanship seems to have been in such a context, a few weeks after the magazine appeared, by Democratic presidential candidate Adlai Stevenson criticizing Dulles for "boasting of his brinkmanship, ... the art of bringing us to the edge of the nuclear abyss."
The policy of a nation that pushes a dangerous situation to the limits of safety (the “brink”) before pulling back; an aggressive and adventurous foreign policy.
