Amazon.com description: Product Description: Military strategists in four countries have boasted that they can cripple the U.S. with an EMP attack. Other countries have protected their power grids from an EMP attack. The U.S. power grid is still vulnerable. A widespread power outage could take years to restore because the EMP destroys electronics including circuits and transformers.

Even unplugged electronics can be damaged. Only electronics stored in a faraday cage are protected. 

Fuel, communications, power, water, and food will be unavailable within hours when emergency fuel runs out. Gas pumps and even pipelines rely on electronics.
Mob violence from mass evacuation of uninhabitable metropolitan areas will be a significant security issue within days. This book describes the risks and details how to prepare and survive.

Readers should also prepare for a potential nuclear attack. Radiation Survival: How to Prepare Now and Survive Radiation Exposure, is now available.
