A group of US lawmakers have called for strategic dialogue with Moscow. They feel that the matter is “more urgent” following Russian President Vladimir Putin’s unveiling of a number of cutting-edge weapons systems. “A US-Russia Strategic Dialogue is more urgent following President Putin’s public address on March 1st when he referred to several new nuclear weapons Russia is reportedly developing, including a cruise missile and a nuclear underwater drone,” a letter signed by US Senators Edward J. Markey (D-MA), Jeff Merkley (D-OR), Dianne Feinstein (D-CA), and Bernie Sanders (I-VT) reads.
