Russia’s invasion of Ukraine has settled into a grinding, no-end-in-sight war of attrition. Tens of thousands of drones now swarm the skies, threatening the lives of millions of Ukrainians near the frontline as well as western cities like Kyiv. Russian drones are now capable of flying nearly 40 or 50 kilometers, putting entire cities near the border within striking distance. Urban warfare in Ukraine’s eastern Donetsk region has become slow, bloody and devastating for the Ukrainians who still live there. Miller says that drone warfare means nowhere in Ukraine is safe.
