Societal factors such as public opinion, interest groups, and the media can influence foreign policy choices and behavior. To date, the public opinion and foreign policy literature has focused largely on data derived from the US, although this trend has begun to change in recent years. However, while much of the scholarly work suggests that public attitudes on foreign policy are both reasonable and structured, significant controversies exist over the public’s general influence on policy as well as the influence of elections on foreign policy. Meanwhile, the study of interest groups as a domestic source of foreign policy is dominated by two points of emphasis: ethnic groups acting as interest groups and the US case. These are most often considered together. This ethnic interest group literature stands largely apart from the literature on trade interest groups, which takes its inspiration from the economics literature. Finally, two aspects of media are specifically relevant to media and domestic sources of foreign policy. The first is the way the media serve as an arena of domestic political competition within democracies, and the second is the communicative role that media play in the formation of public opinions that are specific to and critical to foreign policy decision making.

Terrorist violence appeals to and pivots on the creation and dissemination of fear. In that respect, it hinges on public perceptions and threat manufacturing to have policy impact. Scholars have long recognized that terrorist actors appeal to multiple audiences, including the public audience. By sowing fear, actors hope that the public will put pressure on the target regime to enact policy concessions to militants or that policymakers, fearing the erosion of public support, will bend to the terrorists’ demands. Recognizing this, it behooves scholars to delineate the mechanisms that shape perceptions and parse the different types of emotional and cognitive responses that terrorist violence arouses. Violence inculcates a range of public responses, most notably, anxiety, fear, anger, and perceptions of threat. These responses may vary with individual demographics, such as gender and age, but are also guided by the political environment in which individuals are embedded. Variegated emotive responses have important policy consequences as distinct emotions are associated with different policy demands. On the whole, psychological reactions to terrorism underlie the effectiveness of terrorism and have downstream social, political, and cultural ramifications.
