Leaders in both the United States and Europe are scrambling to figure out how to deter Russia from invading Ukraine and how to respond if Moscow does in fact go through with military aggression. In continuation of our series of rapid reactions to this constantly developing crisis, Michael Kofman and Angela Stent join Andrea Kendall-Taylor and Jim Townsend to discuss how events are likely to unfold in the coming weeks. Michael Kofman serves as an Adjunct Senior Fellow for the Transatlantic Security Program at the Center for a New American Security, as well as Research Program Director in the Russia Studies Program at CNA and as a Fellow at the Kennan Institute at the Woodrow Wilson International Center in Washington, DC. His research focuses on Russia and the former Soviet Union, specializing in Russian armed forces, military thought, capabilities, and strategy. Angela Stent is Senior Adviser to the Center for Eurasian, Russian and East European Studies and professor emerita of government and foreign service at Georgetown University. She is also a nonresident senior fellow at the Brookings Institution and co-chairs its Hewett Forum on Post-Soviet Affairs.
