In the event of an EMP attack, the US would be in dire shape and it would last for a very long time. Electricity is the oxygen of America. Without it, we would be back in the 19th century in terms of everyday living with candles and oil lamps. The factories would shut down and many people would freeze to death in their homes. The most vulnerable Achilles heel of America is the power grid. Without electricity, we wouldn't have the use of much of what we take for granted right now. Think about it.....what do you use that is electronic or runs off of a continuous source of electricity?
