ISW Update: Ukraine Advances Amid Russia’s Strained Economy and Ongoing Attacks
ISW’s May 15, 2026 assessment notes Putin portraying Russia’s economy as strong despite clear strain, while Zelensky warns of Russia reconnoitering near Kyiv. Sanctions relief paired with slowed Patriot interceptors could raise the threat of missile strikes on Ukraine. A Russian state poll shows a small rebound in Putin’s approval. The two sides exchanged 250 prisoners as part of a 1,000-for-1,000 deal. On the battlefield, Ukrainian forces advanced near Kharkiv and Kostyantynivka; Russia launched missiles and drones overnight, while Ukraine struck Russian oil infrastructure in Ryazan Oblast, naval assets in Dagestan, and aircraft in Krasnodar Krai.
