RUSSIA-US-MISSILE-DEFENCERussia is covertly developing and testing nuclear missiles in violation of the 1987 Intermediate-range Nuclear Forces (INF) Treaty and the Obama administration to date has failed to hold Moscow accountable, according to arms control specialists. “The Russians have basically violated every major treaty they’ve ever entered into, certainly every major weapons treaty,” said Sen. Marco Rubio (R., Fla.), a member of the Senate Foreign Relations and Intelligence Committees. He is also a leader of a Senate arms control group. The comments were made at a panel discussion Tuesday at the Heritage Foundation on Russian violations of the INF treaty. The Free Beacon first reported in October that a Russian test of a new missile, the RS-26, violated the INF treaty. The accord prohibits ballistic missiles with ranges of 5,500 kilometers (3,415 miles) or less, and cruise missiles with ranges less than 500 kilometers (310 miles). More
