When Russia invaded Ukraine in February 2022, the conventional wisdom was that the capital, Kyiv, would soon fall and the rest of the country wouldn’t last long against a much larger enemy.

Russia launched “one of the largest air attacks” of the war overnight, Ukraine’s foreign minister said, firing more than 200 missiles and drones at the country’s energy infrastructure. Andrii Sybiha said Russia targeted “critical infrastructure” in “peaceful cities,” causing “preventative” outages.
