ISW: Russian Offensive Stalls as Ukraine Regains Ground Across Front

ISW says Russia has failed to make significant operational progress in the past year, while Ukraine has regained territory across the front—including parts of Kupiansk and major gains in the south—driven by Ukrainian counteroffensives and long-range strikes. The May ceasefire lacked enforcement mechanisms, suggesting it won’t hold without stronger monitoring, and Moscow’s capacity for large-scale offensives remains constrained ahead of Victory Day.
