Russia’s manipulation of Ukraine, which culminated in the 2022 invasion, demonstrated that Russia was willing to resort to all means necessary to secure a regional sphere of influence that included Ukraine. But events could have taken a different direction. Using the concept of national identity as a starting point, RAND researchers developed a framework to illuminate the underlying causes of the Russia-Ukraine war.

Understanding Russia’s grand strategy can help U.S. decisionmakers assess the depth and nature of potential conflicts between Russia and the United States and avoid strategic surprise by better-anticipating Moscow’s actions and reactions. The authors of this report review Russia’s declared grand strategy, evaluate the extent to which Russian behavior is consistent with stated strategy, and outline implications for the United States.

The challenge of deterring territorial aggression is taking on renewed importance, yet discussion of it has lagged in U.S. military and strategy circles. The authors aim to provide a fresh look, with two primary purposes: to review established concepts about deterrence, and to provide a framework for evaluating the strength of deterrent relationships. They focus on a specific type of deterrence: extended deterrence of interstate aggression.
