The Conduct and Consequences of War

The academic study of warfare has expanded considerably over the past 15 years. Whereas research used to focus almost exclusively on the onset of interstate war, more recent scholarship has shifted the focus from wars between states to civil conflict, and from war onset to questions of how combatants wage and terminate war. Questioned as well are the longer-term consequences of warfare for countries and their populations. Scholarship has also shifted away from country-conflict-year units of analysis to micro-level studies that are attentive to individual-level motives and explanations of spatial variation in wartime behavior by civilians and combatants within a country or armed conflict. Today, research focuses on variations in how states and rebel groups wage war, particularly regarding when and how wars expand, whether combatants comply with the laws of war, when and why conflicts terminate, and whether conflicts end with a clear military victory or with a political settlement through negotiations. Recent research also recognizes that strategic behavior continues into the post-conflict period, with important implications for the stability of the post-conflict peace. Finally, the consequences of warfare are wide-ranging and complex, affecting everything from political stability to public health, often long after the fighting stops.
