“The Kh-47M2 Kinzhal (in Russian: Х-47М2 Кинжал, “Dagger”, NATO reporting name Killjoy) is a Russian nuclear-capable hypervelocity aero-ballistic air-to-surface missile. It has a claimed range of more than 2,000 km (1,200 mi), Mach 12 speed (2.5 mi/s), and an ability to perform evasive maneuvers at every stage of its flight.”

I have been pulling for a swift end to the SMO. After reading this article, I am coming to believe that it will last until AI, communication technology and drone/robotics become mature enough to efficiently clear trenches and citiscapes.
This is all pretty frightening when you think how these technologies may be used in "peacetime."
