Russia’s unjustified aggression against Ukraine has revitalized NATO, and this new energy was on display at the recent 75th anniversary summit of the alliance. While there were some long-term decisions to boost European deterrence against the Russian threat, other key questions were left unanswered. Can Ukraine become a full member of the alliance? When can this happen? The open-ended confrontation in Eastern Europe, and the risks posed by a belligerent Russia, have resulted in a situation that is more ripe for escalation than the darkest days of the Cold War.

In this episode, renowned historian Mary Elise Sarotte discusses the roots of the current crisis. Author of Not One Inch: America, Russia, and the Making of Post–Cold War Stalemate, Mary Elise Sarotte is also Marie-Josée and Henry R. Kravis Distinguished Professor of Historical Studies at Johns Hopkins University. What should the U.S. and Europe do before it’s too late to help Ukraine? How are the historical cases of Norway and West Germany joining NATO relevant to Ukraine today? What can history teach us when it comes to preventing the security situation in Europe from getting even worse?
