Answer:
Who was known for his policy of massive retaliation and his approach to was called brinkmanship was John Foster Dulles, Secretary of State from 1953 to 1959.
Explanation:
Brinkmanship is a type of strategic policy developed during the Cold War by John Foster Dulles, member of Eisenhower's administration. After World War II, the countries of the capitalist and communist blocs began to accumulate conventional and nuclear weapons, which led to a real arms race. In this process of accumulation of military power, the strategy went through two distinct phases during the first years of the Cold War: "massive retaliation" and brinkmanship. The latter refers to a type of strategy based on cowarding and impressing the enemy through military superiority, to the point of bringing threats against the enemy or adversary of war to the brink of conflict. This tactic was used to keep the enemy at bay and even to propitiate his withdrawal from a certain territory it had occupied.
