The Second United Nations Conference on the Exploration and Peaceful Uses of Outer Space — UNISPACE-82 — convenes in Vienna with explicit hopes of negotiating a binding ban on weapons in space. Both the United States and the Soviet Union refuse to surrender the option, and the conference closes with a non-binding final report and an exhausted secretariat.
The pattern recurs at UNISPACE-III in 1999 and at every UN COPUOS session since. The lesson, drawn quietly across forty years of multilateral diplomacy, is that the great powers will not agree to a treaty constraining what they can do in orbit. Sovereignty in space is, by default, do-it-yourself.
