A Treaty Banned This Missile System for 32 Years. Russia Broke the Treaty, and Now the US Army Has It.

The 1987 Intermediate-Range Nuclear Forces Treaty banned American and Russian ground-launched missiles with ranges between 500 and 5,500 kilometres for more than three decades. The United States withdrew in 2019 after Russia developed, flight-tested and deployed a prohibited system known as the 9M729. Typhon is the most visible result.
