Russia’s ‘Nuclear Saber-Rattling’ Under U.S. Scrutiny

The U.S. and NATO are studying the ramifications of Russia’s Cold War-style rhetoric about its nuclear preparedness, America’s ambassador to NATO said, as the Western alliance steps up reinforcement of its eastern borders.

Military chiefs are assessing “the possible implications of what Russia says about it nuclear weapons -- its doctrines, its pronouncements, its rhetoric -- and what we actually see on the ground,” Douglas Lute, U.S. envoy to the North Atlantic Treaty Organization, told reporters in Brussels on Tuesday.
