EMP this is something that should scare everyone. Everyone is afraid of nuclear war and we should be but even worst would be an EMP attack. This could be done high up in the atmosphere with an nuclear weapon this would not kill directly but would destroy all electronics this means you electricity, car, telephone, radio, TV, and internet. Also people who have heart passer who not be long and all food in the cities would run out hospitals even the ones that have backup generator would be effected. Prescription drugs would be in short supply. There are estimates that 85% of the population would die in the first year. Even a standard war would not kill that many. There are ways of protecting the power grid but the government is not interested it would rather spend its money on military which can prevent this from happening. The experts say an EMP attack could send the US back to the Stone Age. Newt Gingrich told the members of Congress 2 years ago and nothing done he claimed we need to set up our electrical system to withstand an EMP . We can also get an EMP from the sun which could put the word back to the Stone Age.
