The head of Britain’s armed forces has warned that the world stands at the cusp of a “third nuclear age,’’ defined by multiple simultaneous challenges and weakened safeguards that kept previous threats in check.
Admiral Tony Radakin, chief of the defense staff, said Britain needs to recognize the seriousness of the threats it faces, even if there is only a remote chance of Russia launching a direct nuclear attack on the U.K. or its NATO allies.
