An EMP Attack, Thinking The Unthinkable – James Carafano

When the 9/11 Commission issued its report, it complained that federal agencies had a colossal “failure of imagination.” Nobody could accuse Newt Gingrich from suffering that shortfall.
When he delivered a major address on national security last week, the former Speaker of the House went after Defense Secretary Robert Gates for planning for the future the Pentagon wants, rather than dealing with the many serious problems it may actually face. Gingrich mentioned one challenge that many find too terrible to contemplate — which is why our government should spend a lot more time doing exactly that.
I’m referring to the Electro-Magnetic Pulse (EMP). This method of attack is usually associated with a nuclear blast. In addition to thermal, radiation, heat and concussive force, an atomic detonation throws off an incredible amount of electro-magnetic energy.
Picture a massive tsunami, but with lightning instead of water. And, like the surge produced by lightning, electrical systems act like antennas sucking down a rush of electrons that fry circuits and burn out micro-chips.
EMP is not normally addressed when talking about nuclear attack, because most nuclear strikes are planned as low-air bursts where most of the energy, EMP included, go straight into the ground (and flattening the city in-between). In such scenarios, electrical systems would be disabled by EMP, though few would notice, because most people would have been crushed or melted in the firestorm following the detonation.
A deliberate EMP attack, however, would be different. If, for example, an enemy detonated a nuclear weapon carried on a ballistic missile 200 miles or so above the earth, people on the ground might never know an attack occurred. But if the explosion happened high enough over North America, the blossom of EMP might cover the entire United States.
