On August 2, 2019, the Intermediate-Range Nuclear Forces Treaty ended after the United States and Russia both withdrew. The US suspended its obligations in February 2019, citing Russia's deployment of the 9M729 ground-launched cruise missile as a treaty violation. Russia denied noncompliance and characterized the US withdrawal as dismantling arms control architecture. The treaty's collapse ended 32 years of binding elimination of intermediate-range nuclear weapons. Both parties subsequently announced development of missile systems previously prohibited under the treaty.
