John Foster Dulles, as Secretary of State under President Eisenhower, coined the term "captive nations" to describe the Eastern European countries under Soviet control.

Nixon, Acheson, and Hiss were all notable American statesmen, but they did not play a significant role in the formation or implementation of this policy.
