“Russian President Vladimir Putin, in a decision that was widely expected, suspended his country’s observance of a key nuclear arms control pact on Saturday in response to a similar move by the United States a day before,” the New York Times reports.
“But adding to a sense that the broader architecture of nuclear disarmament has started to unravel, Mr. Putin also said that Russia would build weapons previously banned under the treaty and would no longer initiate talks with the United States on any matters related to nuclear arms control.”
