North Korea has threatened nuclear attacks on Seoul and Washington as South Korea and the US began annual military drills on Monday.
Nuclear weapons, as they say, are under the control of “imperfect humans inside imperfect organizations,” so things from time to time go wrong. “The systems are not failsafe,” Mark Fitzpatrick, head of the Americas office of the International Institute for Strategic Studies, tells The National Interest. “There have been too many cases of mistaken symbols. We’ve just been lucky they didn’t result in retaliation by mistake.”
