This 1953 Journalism Quarterly article by Burton Paulu entitled "Smith-Mundt Act- A legislative history" (3.7mb PDF) is an interesting and short read for anyone wanting to know more about the early discussions around the start of U.S. public diplomacy. The timing of this particular paper is interesting.
It was based on Burton Paulu's PhD thesis that he completed in 1949 and was published in 1950. The title of the original work is typical of a PhD thesis: Factors in the attempts to establish a permanent instrumentality for the administration of the international broadcasting services of the United States. A short title could simply be 'The Challenges of Creating VOA, 1945-1949'.
Paulu likely timed the publication of this article in with the ongoing reviews of U.S. public diplomacy underway in 1952 and 1953. These included efforts by the Advisory Commission on Information and a committee lead by Nelson Rockefeller. Both led to removing the information activities from the State Department and establishing the United States Information Act.
By this time, the support from State for these activities had waned considerably. Even contemporary watchers noted that State was overall an unwilling owner of the programs and that the departure of key leadership meant the bureaucracy was working to eject what it did not want, regardless of changes in the conduct world affairs. Even former supporters of empowering State were reconsidering whether the Department was capable of effectively running these programs. The debates Mr. Paulu describes have a striking resemblance to modern discussions, particularly those between 9/11 and 2010.
Despite Mr. Paulu's proximity to events, there are a couple minor errors in his paper. One such example is the history of the bill starts with Congressman Karl E. Mundt, Republican of South Dakota, in January 1945. The Chairman of the House Foreign Affairs Committee, Sol Bloom, Democrat of New York, took Mundt's bill and reintroduced it under his own name in July, and again in October 1945, which is when Mr. Paulu picks up the story. The October edition had been quickly modified following President Truman abolishing the Office of War Information and moving several operations, and a massive number of personnel, into the State Department.
The excerpt above is important. The 'the question of whether it is safe to expose the American people to unsecured radical opinions, especially those from abroad' was aimed at the exchange of people, not U.S. international broadcasting. A strong resistance to exchanges was the potential to 'corrupt' American minds by exposing them to Communism, either here in the U.S. or abroad.
