Ukraine preparing for another winter campaign Shmyhal said Ukraine hopes its long-range strikes against Russian oil refineries and tougher Western sanctions will pressure Moscow into ending the war this autumn. However, he warned Kyiv is preparing for another winter of large-scale attacks on critical infrastructure if the fighting continues. According to the minister, Ukraine is constructing protective shelters for electricity, water, and gas facilities while expanding the use of modular boilers and power generators that are harder for Russia to destroy than large centralized plants. “Ukraine has acquired the ability to adapt very quickly to crises, to challenges,” Shmyhal said.
