When United States dropped atomic bombs in Hiroshima, and three days later in Nagasaki, it marked the end of World War II. This also marked the start of a nuclear arms race between the two dominant forces of the world: United States and the Soviet Union. This nuclear arms race was a key issue of the Cold War, having a series of tests that increase the tension between the two countries who looked for supremacy in nuclear warfare.
George Creel headed the Committee on Public Information
during the time the U.S. joined the First World War. They used every method
within their disposal to convince Americans to support the war effort. They used printing posters, radio programs
and even the movies to convince public opinion that it was necessary for
America to take part in the war.
