“Russia has for years been developing, testing and deploying a missile that violates a landmark nuclear weapons treaty, a senior White House official said Tuesday, making a case for the administration’s planned withdrawal from the accord ahead of a scheduled meeting between the leaders of the two nations. The nuclear-capable missile, the official said, can reach over 300 miles (500 kilometers), in violation of the Intermediate-Range Nuclear Forces Treaty, which was signed amid Cold War hostilities in 1987 and which the Trump administration is now seeking to exit. Russia developed the weapon between 2000 to 2010 and completed testing by 2015, the official said. But when questioned about it in recent years, Moscow officials have denied violating the treaty and demanded to know how the U.S. detected the apparent violation, the official said. The official said the Trump administration believes it was Russia’s intention to keep the U.S. constrained by the treaty while they developed and deployed the illegal missiles that threaten Europe. Russia has denied that it has violated the treaty, saying the 9M729 has not been tested for the range that would make it prohibited. Moscow has also alleged the United States has also breached the accord.”
