Russian Compliance with the Intermediate Range Nuclear Forces (INF) Treaty: Background and Issues for Congress [October 20, 2016] [open pdf - 746KB]
"The United States and Soviet Union signed the Intermediate-Range Nuclear Forces (INF) Treaty in December 1987. Negotiations on this treaty were the result of a 'dual-track' decision taken by NATO in 1979. [...] The U.S. State Department, in the 2014, 2015, and 2016 editions of its report 'Adherence to and Compliance with Arms Control, Nonproliferation, and Disarmament Agreements and Commitments,' stated that the United States has determined that 'the Russian Federation is in violation of its obligations under the [1987 Intermediate-range Nuclear Forces] INF Treaty not to possess, produce, or flight-test a ground-launched cruise missile (GLCM) with a range capability of 500 km to 5,500 km, or to possess or produce launchers of such missiles.' [...] The United States has raised its concerns about Russian compliance with the INF Treaty in a number of meetings during the past few years. [...] The United States could also consider a number of options for how it might respond if Russia withdraws from the INF Treaty and deploys new INF-range missiles. It could develop and deploy new military capabilities--including, possibly, new land-based INF-range missiles or new missile defense capabilities--to offset the threat posed by new Russian INF-range missiles. The United States could also take other steps with its allies to assure them of the U.S. commitment to their defense. Congress is likely to continue to conduct oversight hearings on this issue, and to receive briefings on the status of Russia's cruise missile program. It may also consider legislation authorizing U.S. military responses and supporting alternative diplomatic approaches."
