Ukraine's counteroffensive, launched three months ago amid increasing pressure to turn the tide of the war, has made meager gains on its eastern and southern fronts against tough Russian defenses of minefields and trenches. Russia's war of aggression is now a war of attrition, and it's unclear which side may crack first. The high casualty figures -- an estimated 500,000 dead and wounded since the war began 18 months ago -- and lack of offensive progress are drawing comparisons to the First World War, whose aggressors also believed it would be over quickly. In this episode, Anatol Lieven of the Quincy Institute for Responsible Statecraft discusses what it will take to bring the war to an end, and why we should all be concerned with the darker parallels to the Great War a century ago.
