In Eastern Europe, tens of thousands of Russian troops are gathering along Russia’s border with Ukraine. US intelligence officials see this as a potential planned invasion into Ukrainian territory. The Biden administration has been warning US allies in Europe and has tried to rally a resolute response to Russian pressure. On Tuesday, President Joe Biden will have a much-anticipated virtual meeting with Russian President Vladimir Putin. Host Marco Werman speaks with Andrea Kendall-Taylor, a senior fellow at the Center for a New American Security and the director of their trans-Atlantic security program.
