Who was known for his policy of massive relations and his approach to war called a brick kinsman ship?

The individual known for his policy of massive retaliation and the approach to war referred to as "brinkmanship" was U.S. Secretary of State John Foster Dulles during the Cold War. Brinkmanship involved pushing dangerous situations to the edge of conflict to compel an opponent to back down. This strategy was part of a broader framework of containment and deterrence against the spread of communism, particularly in relation to the Soviet Union.
