The Iranian government knows that it can not stand toe-to-toe with the United States. The only hope they have of defeating the “Great Satan” is to strike us at our most vulnerable point, our Achilles heel if you will; our electronic infrastructure.
When an EMP nuclear weapon explodes at height (200-300 miles), every circuit board within the line of sight of the weapon will overload and fry. In a matter of seconds, the US would effectively be sent back in time to the 1800′s, without the infrastructure to support 311 Million people. Experts say that up to 90% of the population of the United States could die as a result.
