Unipolarity and the increasing frequency of US military intervention
Ever since the end of the Cold War, scholars have debated whether unipolar international systems promote peace or foster conflict. Yet decades later, the empirics of this question remain underexplored, as the debate has mostly been addressed from a theoretical perspective. We advance this debate by systematically comparing the frequency of US military interventions abroad during the bipolar Cold War (1945–1990) and the unipolar post-Cold War era …
Blowback Operations as Rebel Strategy: How Sectarian Violence Spread from Syria into Lebanon, 2013-14
Why and how do conflict and violence spread across international borders? This article introduces a new theoretical framework for blowback operations, where a civil war combatant launches terrorist attacks in the home country of a foreign actor to compel this actor to end a military intervention. Using this framework, we explain how military intervention by Hezbollah in Syria sparked a bombing campaign by Sunni jihadi groups inside Lebanon. Novel…
Friend or Foe: Militia Intelligence and Ethnic Violence in the Lebanese Civil War
Starvation as Siege Tactics: Urban Warfare in Syria
Famine is on the rise across conflict zones worldwide. Yet in Syria – unlike other contemporary wars – the phenomenon is concentrated in urban areas, and intensified significantly after 2015. To explain these outcomes I delve into the nature of urban warfare. Urban combat operations favor the defender, and many military organizations resort to siege warfare to conquer urban territory; starvation remains a powerful siege tactic. Qualitative eviden…
When Do Displaced Persons Return? Postwar Migration among Christians in Mount Lebanon
Under what conditions will forcibly displaced persons return to their original homes after wars end? We draw on theories of labor migration to show that even displaced persons who have positive feelings toward their original location may nevertheless choose to return as regular visitors rather than permanent residents unless the location offers attractive economic opportunities. Furthermore, we argue that violence can create negative emotions not…
Toxic waste dumping in conflict zones: Evidence from 1980s Lebanon
Records show that numerous countries experiencing civil wars – including Angola, Eritrea, Lebanon, and Somalia – witnessed environmental crime, such as the dumping of toxic waste. To explore the dynamics of waste crime in conflict zones I combine a historic overview of the international trade in toxic waste with a case study of the 1987 toxic waste dumping scandal in Lebanon. I show that conflict zones provide ideal conditions for waste criminals…
Ethnic Cleansing and the Politics of Restraint: Violence and Coexistence in the Lebanese Civil War
What happens when an armed group has military incentives to engage in ethnic cleansing, but political incentives to abstain? I argue that militants can solve this dilemma by collecting intelligence that allows them to discriminate between neutral and militant non-coethnics and target only the latter. Armed groups are better able to do so in intermixed areas, where loyal coethnics provide intelligence, and thus more likely to perpetrate selective …
