On September 20th, Ukraine sent more than a thousand drones toward Moscow in the largest aerial assault of the war — a moment that reframes what it means to wage modern conflict without air superiority. A nation that did not manufacture combat drones before the invasion has, in less than three years, built the industrial and strategic capacity to strike deep into the heart of its adversary. The attack is less a single event than a threshold crossed: the costs of this war are no longer contained to the front lines, and the distance between combatants no longer offers the protection it once did.
