Last month, Uncommon Knowledge with Peter Robinson asked Princeton Professor and Hoover Institution Senior Fellow Stephen Kotkin 5 questions, all in the foreign policy and history realm. Since then, the world has changed in ways that were unimaginable just 3 weeks ago. So we asked Professor Kotkin to come back for a second round of questions, this time all dedicated to one topic: the Russian invasion of Ukraine. And as usual, his answers are concise, incisive, and analytic. If you want to understand this crisis and some possible outcomes, don’t miss this conversation.
