North Korea: After successfully testing a missile capable of launching a satellite, Pyongyang works toward a nuclear warhead small enough for it to carry an electro-magnetic-pulse weapon of our worst nightmares.

When North Korea orbited a failed satellite in December aboard an Unha-3 long-range missile, it was treated in some quarters as a stunt of no real significance or threat. The last Stalinist regime on earth had no deliverable warhead small enough to place on this missile which itself had no great accuracy.

Serious observers, however, noted that any nation capable of putting an object in orbit could deliver an object to any point on the plant, and the ability of North Korea to develop a missile warhead would be a question of when, not if.

Even so, skeptics say, the U.S. already has in place the missile defense, the once-maligned "Star Wars" technology of President Ronald Reagan's dream and developed by prior administrations, to shoot down a solitary missile with a solitary warhead aimed at the U.S.

But would we shoot down another "harmless satellite"?

Such a satellite might not be so harmless at all, and even if carrying only a low-yield nuke, might be capable of a devastating attack in a single orbit at relatively low altitude as it passes over an unsuspecting U.S. by using a technology known as electromagnetic pulse, or EMP.
