Today we're bringing you a bonus episode on the Russian troop buildup on the Ukrainian border, from Crisis Group's global podcast Hold Your Fire!. Olga Oliker, our War & Peace host and Crisis Group’s Europe and Central Asia director, and Oleg Ignatov, senior Russia analyst, join Hold Your Fire! host and Interim President Richard Atwood to discuss what led to the crisis. These include the move forward – for the second time this year – of 100,000 Russian troops, the breakdown of a ceasefire in eastern Ukraine’s Donbas region between Russian-backed separatists and Ukrainian security forces, and Russian President Vladimir Putin’s increasingly testy statements about Ukraine’s relations with NATO member states. Ukrainian officials warn of a potential Russian invasion; Western leaders warn of severe consequences if that happens.  Olga, Oleg and Richard look at what Putin may hope to gain with the army deployments, whether Moscow is really prepared to use force, what a military intervention might entail and how Ukraine and its Western partners might respond. They also look at what Western powers could do to deter an attack. For more information, explore Crisis Group’s analysis on our Ukraine and Russia pages.
