Wartime rape is neither ubiquitous nor inevitable. The level of sexual violence differs significantly across countries, conflicts, and particularly armed groups. Some armed groups can and do prohibit sexual violence. Such variation suggests that policy interventions should also be focused on armed groups, and that commanders in effective control of their troops are legally liable for patterns of sexual violence they fail or refuse to prevent. Wartime rape is also not specific to certain types of conflicts or to geographic regions. It occurs in ethnic and non-ethnic wars, in Africa and elsewhere. State forces are more likely to be reported as perpetrators of sexual violence than rebels. States may also be more susceptible than rebels to naming and shaming campaigns around sexual violence. Perpetrators and victims may not be who we expect them to be. During many conflicts, those who perpetrate sexual violence are often not armed actors but civilians. Perpetrators also are not exclusively male, nor are victims exclusively female. Policymakers should not neglect nonstereotypical perpetrators and victims. Wartime rape need not be ordered to occur on a massive scale. Wartime rape is often not an intentional strategy of war: it is more frequently tolerated than ordered. Nonetheless, as noted, commanders in effective control of their troops are legally liable for sexual violence perpetrated by those troops. Much remains unknown about the patterns and causes of wartime sexual violence. In particular, existing data cannot determine conclusively whether wartime sexual violence on a global level is increasing, decreasing, or holding steady. Policymakers should instead focus on variation at lower levels of aggregation, and especially across armed groups.
