What really happens if North Korea launches a nuclear missile
If North Korea launched a nuclear missile, the United States would have minutes to react. Infrared satellites would detect the launch, radar systems would track it, and a network of missile defenses would attempt to destroy it mid-flight.
Matt Korda, the associate director of the Nuclear Information Project at the Federation of American Scientists, assisted USA TODAY in identifying 50 silos near Malmstrom Air Force Base, Montana, that were deactivated in the late 2000s and later destroyed. That left USA TODAY with a list of 450 targets for our strike simulations.
