Obama hit North Korea's nuclear program with cyber attacks

Former President Barack Obama wasn't impressed by the United States' missile defense systems. They constantly missed incoming blasts in practice, to say nothing of how they might fare in the face of an actual assault. 

Obama was thinking about North Korea and its leader, Kim Jong-un, who's often going on about developing a nuclear warhead that can be fired atop an intercontinental ballistic missile. If this ever happened, U.S. defenses may well not be able to stop it. So, according to a Saturday report by The New York Times, Obama ramped up American cyber-attacks on North Korean computer networks.
