Recurring pro-Kremlin disinformation narrative about the INF Treaty. Extensive evidence has been provided of Russia's violations of the INF Treaty.
Russia bears primary responsibility for the end of the INF Treaty, because it has produced, tested and deployed the 9M729 missile, which violates the agreement. In July 2014, then-US President Obama officially accused Russia of testing a missile in violation of the INF Treaty, which prohibits the US or Russia from possessing, producing or test-flying ground-launched ballistic and cruise missiles with a range between 500 and 5500 kilometres.
In a joint statement released after the meeting held at NATO Headquarters in Brussels on Tuesday 4 and Wednesday 5 December 2018, NATO Foreign Ministers stated that the United States has remained in full compliance with its obligations under the INF Treaty since it entered into force and that Russia has developed and fielded a missile system, the 9M729, which violates the INF Treaty and poses significant risks to Euro-Atlantic security."
US and NATO have repeatedly engaged with Russia to preserve the INF treaty. For background on pro-Kremlin myths on the INF Treaty see here.
