ISW: Russian Offensive Stalls in June 2026 Amid Ukrainian Counterattacks
ISW reports that Russia’s spring-summer 2026 offensive has failed to secure operationally significant gains; June 2026 saw only about 30.4 square kilometers gained at an average pace of 1.01 sq km per day, far slower than June 2025. Ukrainian counterattacks in Kupyansk and Oleksandrivka remain effective, with gains concentrated in Kostyantynivka’s urban terrain at high cost. In the first six months of 2026 Russia seized or infiltrated about 622.6 square kilometers, roughly 28% of the 2025 six-month total, and suffered heavy casualties and equipment losses. Ukrainian long-range and intermediate-range strikes are disrupting Russian logistics and oil infrastructure, causing gasoline shortages and pressuring refinery capacity. Russia has closed seven railway border crossings with Finland, Latvia, and Estonia and is leaning on crude exports while importing refined fuels from India. Belarusian airspace and signal repeaters remain contested. Overall, ISW expects no rapid Russian breakthrough and continued attrition in the near term.
