Note – An extended grid down situation is one thing that would take America out of the end time equation and accelerate the fulfillment of what the prophets prophesied as taking place around Israel at the end of the age. This grid failure could happen because of a solar or nuclear EMP or it may even take place because of a sophisticated cyber attack.
I have read many articles and written several articles myself on the danger of any EMP attack on America, but I ran across what I think is the best scientific description and analysis of the three components (E1, E2, and E3) from a nuclear EMP that I have read.
