This study analyzes U.S. regulations on government propaganda, and provides suggestions for Taiwan. This paper focuses on the following three main questions: What are the U.S. regulations against improper government propaganda? How does the U.S. government rectify this problem? What is the difference between Taiwan and the U.S. on government propaganda regulations? To address these questions, this paper is divided into the following three sections: (1) an introduction of U.S. regulations on government propaganda; (2) a review of two significant cases that demonstrate how the U.S. government investigates and rectifies inappropriate propaganda; and (3) an analysis of the strengths and weaknesses of U.S. regulations. A comparison between the relevant regulations in Taiwan and those in the U.S. is also preformed. Finally, this study concludes with suggestions for how the Taiwanese government can further revise laws to ensure that regulations on government propaganda are comprehensive. Amendments to related laws should include the following: (1) defining government propaganda and categorizing the different features of propaganda; (2) developing a penalty for violating the laws; (3) requiring the media to disclose sponsor information; and (4) defining the social responsibility of the media and its workers.
