Three Steps to Avert an Accidental Nuclear War
Human error, cyberattacks and Cold War postures are increasingly likely to set off a global disaster.
by Ernest Moniz and Sam Nunn

Some salient points -
American leaders have been warned more than once of incoming Russian missiles -- in each case, it was a false alarm resulting from technical or human error. Former Russian President Boris Yeltsin was mistakenly alerted to a possible U.S. missile strike after the launch of a Norwegian scientific rocket.
The risks of human error involving nuclear weapons are compounded by the potential for deliberate cyber-threats to warning and command-and-control systems. Hackers could insert a false warning of a nuclear attack into national warning and alert systems and falsely attribute that attack to an innocent country. At a time of heightened global tensions -- with too little communication or cooperation between nuclear rivals, and only minutes of decision time -- how would leaders of states with nuclear weapons respond?
