How did President Eisenhower and John Foster
Dulles change the tone of the arms race?

The government of the 35th President of the United States, Dwight Eisenhower (1953-1961), was called the “Cabinet of 17 Millionaires,” as it included representatives of the largest US corporations that enriched themselves on military orders during the war and the first post-war years. It was obvious that the new government would be even more active in developing the arms race and escalating international tension in the interests of "big business." John Foster Dulles became US Secretary of State; he proclaimed the “policy of liberation” as the basis of US foreign policy. Dulles demanded the "liberation" of "Latvia, Lithuania, Estonia, Poland, Czechoslovakia, East Germany, Hungary, Bulgaria, Romania, Albania, Mongolia, Tuva, China, North Korea, the Habomai and Shikotan islands. Two military doctrines were associated with the concept of "liberation," in other words called the concept of "dropping communism," which was intended to provide a general justification for the US foreign policy platform - "a new look" and "massive retaliation."

At a meeting in the White House in late December 1953, Eisenhower announced his readiness to unleash a preventive "total" thermonuclear war. The buildup of the country's military potential was accompanied by a buildup of fears about the likelihood of an outbreak of war. In purely military terms, it was decided to concentrate US efforts on improving strategic thermonuclear weapons and strategic aviation as a means of their delivery in order to dictate the terms to the USSR from a position of strength.
