In his newly published book, Nuclear High-Attitude Electromagnetic Pulse, Steven Starr shows that all it takes is one nuclear explosion to shut down  the United States and throw the population back into the Dark Ages.  The electric power grid would be destroyed along with the communications system, the cooling systems at nuclear power plants and all electronic devices.  The reason is that civilian infrastructure is not protected from ElectroMagneticPulse (EMP). The military has taken steps to shield its weapon and communication systems, but nothing has been done to protect civilian infrastructure.  Bills mandating EMP protection have been defeated in Congress.
