Contemplating a defense for a futuristic weapon

The topic of a resolution introduced by request of the Joint Legislative Armed Services committee, sounds like something from a 1950's era science fiction movie, but those involved in planning to guard against an Electromagnetic Pulse Attack are serious about the threat's implications. Congress formed a commission to look at how to plan for such an attack a few years ago. An electromagnetic pulse attack, or EMP, results from a nuclear device detonating high in the atmosphere creating a shock wave that moves rapidly across the magnetic spectrum-- knocking out electric generation and transmission.Lori Townsend, APRN - Anchorage
