Ukraine has become a proving ground for many of the tactics, techniques, and technologies that will transform that next era of warfare. One recent development foreshadows a novel, potentially strategic threat against the U.S. homeland. CNN reported last week that pro-Ukraine partisan forces have conducted drone strikes, covertly launched from within Russian territory, against targets of both material and symbolic importance — including the Kremlin, a neighborhood in Moscow, and an oil refinery. While those strikes have, for the most part, caused limited damage, their psychological impact has been more significant, undercutting the myth of Russia’s military superiority, as well as the overall rationale of Russian President Vladimir Putin’s so-called special military operation.
