Answer 1

Dulles was Eisenhower's Secretary of State, which is someone who represents the United States to other foreign countries. He advocated an aggressive stance against Communism, and absolutely despised the idea of it. He also advocated for heavy reparations against Germany after World War 1. 

Answer 2

Answer:  Secretary of State

Further context/detail:

The office of Secretary of State is the USA's cabinet-level official in charge of foreign relations and foreign policy.  In other countries, a similar position would be called "Minister of Foreign Affairs."

John Foster Dulles was Secretary of State under President Eisenhower.  He held the office from 1953 to 1959.  He wanted a change from what had been the "containment policy" which the US had followed during the Truman Administration, as recommended then by American diplomat George F. Kennan.   Dulles felt the containment approach put the United States in a weak position, because it only was reactive, trying to contain  communist aggression when it occurred.

Dulles sought to push America's policy in a more active direction; some have labeled his approach "brinksmanship."  In an article in LIFE magazine in 1956, Dulles said, "The ability to get to the verge without getting into the war is the necessary art."  He wasn't afraid to threaten massive retaliation against communist enemy countries as a way of intimidating them.
