On June 1st Ukraine took military raiding into the 21st century. It did so with little more than ingenuity and 117 drones, which emerged from trucks across Russia—everywhere from Siberia to the Chinese border—and destroyed a dozen or so planes in Vladimir Putin’s long-range air fleet. The raid came amid the Russian president’s relentless bombardment of Ukraine. On June 9th he launched his biggest drone strike of the war, sending 479 machines to hit Ukrainian airfields, cities and factories.
