Trump Says US to Exit Nuclear Treaty, Russia Vows Retaliation

President Donald Trump said Washington will exit the Cold-War era treaty that eliminated a class of nuclear weapons due to Russian violations, triggering a warning of retaliatory measures from Moscow. Russian Deputy Foreign Minister Sergei Ryabkov said on Sunday that a unilateral U.S. withdrawal would be "very dangerous" and lead to a "military-technical" retaliation. German Foreign Minister Heiko Maas said that for 30 years the treaty had been a pillar of Europe's security architecture. "We now urge the United States to consider the possible consequences," of quitting the pact, Maas said in a statement issued on Sunday.
