Much of the Cold War was conducted by espionage. The Soviets had their spy agency, the NKVD, which later became the KGB. The British had their spy agency, MI6. But the United States was late to come to the spy game. Because of the lack of decent intelligence, the United States was caught unawares on December 7, 1941. The United States had warnings but they were not heeded. To prevent this from happening again, the Central Intelligence Agency was created in 1947.
The CIA saw as part its mission the shaping of public opinion in foreign country through the promotion of literature. This was made clear in a 1953 government report: "In most parts of the world, the radio and television are still novelties; magazines have low circulation; and newspapers circulate mostly among political groups whose opinions are already formed...Books--permanent literature--are by far the most powerful means of influencing the attitudes of intellectuals." (White, p.9)
