In a presentation to Congress in 1997, George W. Ullrich (deputy director of the Defense Special Weapons Agency) pointed out many issues regarding EMP (electromagnetic pulse) and HEMP (high-altitude electromagnetic pulse) weaponry.

In addition to discussing the potential damages an EMP bomb could wreak on the U.S., he stated:

EMP Technology has been exploited in movies like Ocean’s Eleven and Matrix: Revolutions and now on Jericho on TV, but do you really know how much damage a real E-Bomb can deliver to your corporate door-step when you are not EMP-proof?” asks James Carlini.
