The war has entered the phase of mathematics: cheap Russian missiles are destroying Ukraine's scarce interceptors

Russia launched a major drone-and-missile strike on Kyiv, including the Oreshnik ballistic missile, in apparent retaliation for Ukrainian attacks.

The attack was designed to overwhelm Ukraine’s air defenses, and Kyiv intercepted only part of the barrage.

The strike exposed Ukraine’s shortage of Patriot interceptors and the growing strain of a long air war.

It also highlights Russia’s strategy of exhausting Ukraine’s scarce and expensive defenses to gain an advantage.
