Russian intervention in the Syrian Civil War braced the regime during its nadir and helped reestablish President Bashar al-Assad’s political dominance over much of Syria just two years later. Despite its importance, Russian intervention did not change the character of the counterinsurgency campaign. Rather, the similarities in Russian and Syrian approaches to counterinsurgency preserved Assad’s strategy and optimized Russian intervention, integrating formidable capabilities into an already brutal campaign. Leaders in Moscow and Damascus were aligned in their approaches. Effective patron-client politics facilitated strategic and tactical cooperation and enabled counterinsurgent forces to strike the insurgencies’ center of gravity by targeting Syrian civilians. Forced displacement and the intentional slaughter of noncombatants became a primary means for Russia and Syria to achieve key strategic objectives and turn the tide of the war. However, favorable short-term outcomes do not necessarily presage long-term success. The counterinsurgents punished civilians instead of addressing root causes. Assad has largely avoided addressing popular grievances and influential conditions and his brutality has left Syria ripe for insurgent exploitation. Although Assad’s short-term success seemingly demonstrates the efficacy of authoritarian approaches to counterinsurgency, the conflict’s long-term outcomes remain unclear. As with all insurgencies and counterinsurgencies, it is essential to consider that the results of the Syrian Civil War may change over time.
