Explaining US unilateral military intervention in civil conflicts: A review of the literature

Abstract

Recent third-party use of force in hastening the exit of Libyan leader Muammar Gaddafi illustrates that third-party military intervention is one foreign policy tool among many that leaders may use to achieve desired ends. Numerous works from international relations and foreign policy scholars explain third-party intervention using a variety of approaches and methods, and examining multiple levels of analysis. The survey of the literature provided here contributes to our understanding of US unilateral intervention by examining this phenomenon using both general theories of third-party intervention, as well as more refined foreign policy theories explaining US intervention in particular. As such, the survey includes works employing various approaches and levels of analysis, and thus serves two purposes: (a) to assist in the cumulation of knowledge pertaining to US unilateral intervention through consolidation of theory and empirical findings; (b) to serve as a source from which scholars can identify contradictions and future avenues of research pertaining to third-party intervention.
