There have been several, what if, books written through the decades. William_R_Forstchen has created quite a thought provoking, what if, series of books indeed. If William_Forstchen can't get you to think about some big potential problems, then perhaps its better to remain ignorant.
"The highly-anticipated follow-up to William R. Forstchen’s New York Times bestsellers, One Second After and One Year After, The Final Day immerses readers once more in the story of our nation’s struggle to rebuild itself after an electromagnetic pulse wipes out all electricity and plunges the country into darkness, starvation, and terror.
After defeating the designs of the alleged federal government, John Matherson and his community have returned their attention to restoring the technologies and social order that existed prior to the EMP (Electro-Magnetic Pulse) attack. Then the government announces that it’s ceding large portions of the country to China and Mexico. The Constitution is no longer in effect, and what’s left of the U.S. Army has been deployed to suppress rebellion in the remaining states."
