How was president eisenhower's brinkmanship a change from the foreign policy of truman?

Hi my dear friend,

In an article written in Life Magazine, John Foster Dulles then defined his policy of brinkmanship as "The ability to get to the verge without getting into the war is the necessary art." During the Cold War, this was used as a policy by the United States to coerce the Soviet Union into backing down militarily.
