This chapter examines the academic debates over the relationship between US public opinion, media, and foreign policy. It first considers the nature of US media and public opinion, including democratic expectations of mass media and public opinion, before discussing pluralist and elite approaches to understanding the links between media, public opinion, and foreign policy. It then explores the role of propaganda and persuasion with respect to US power projection, with particular emphasis on the ways in which public opinion and media can be understood as a source of power for — and as a constraint upon — US foreign policy. It also reviews contemporary debates regarding the impact of technological developments, such as the emergence of global media like the internet and social media, upon US power and influence.
