The "Essential Domino" of Military Operations: American Public Opinion and the Use of Force

Abstract

It is a commonly held belief that the foreign policy issue to which the American public is most sensitive is the use of military force. Because American public opinion regarding the use of force is highly palpable, salient, and organized, and because decisions regarding the use of force are some of the most important decisions the nation ever has to consider, the analysis of public opinion regarding military involvement is academically significant and policy relevant. The indication from policymakers is that American military operations require public support. As a result, scholars and analysts have come to realize that public opinion is the “essential domino” of military operations. The relationship between mass American public opinion and the use of military force has become, therefore, the focus of numerous studies and surveys. There are currently several competing explanations—schools of thought—in the literature on why the mass public supports the use of force. This article is an attempt to identify the most prominent schools of thought on public opinion and the use of force, and the central factors associated with each school. Such a review is important to generating policy–relevant guidance pertaining to public opinion and the use of force—an objective made more pressing by the current war against terrorism.
