Nuclear Treaties - 6 - Intermediate-Range Nuclear Forces Treaty
The NATO forces in Western Europe had enjoyed clear military dominance over the Soviet Union up to the late 1970s. The U.S. and other NATO forces bombers and missiles were clearly superior to the old Soviet missiles and bombers. The Soviets moved to balance the NATO arsenal by development and deployment of a new more power generation of mid-range nuclear missiles called SS-20 and Tu22M.
