This document discusses how the 1958 Brussels World's Fair (Expo 58) served as a stage for the ideological battle of ideas during the Cold War. It provides examples of how the U.S. and Soviet pavilions portrayed their countries, with the U.S. pavilion featuring a controversial "Unfinished Business" exhibit highlighting ongoing civil rights issues. The Soviet pavilion promoted communism and technological achievements like Sputnik and color TV. Both superpowers used their exhibits and promotional materials to portray their ideologies in a favorable light and criticize the other on the global stage.
