The Pentagon is moving the headquarters for the North American Aerospace Defense Command (Norad) back into Cheyenne Mountain near Colorado Springs, Colo., a decade after having largely vacated the site.
Why the return? Because the enormous bunker in the hollowed-out mountain, built to survive a Cold War-era nuclear conflict, can also resist an electromagnetic-pulse attack, or EMP. America’s military planners recognize the growing threat from an EMP attack by bad actors around the world, in particular North Korea and Iran.
An EMP strike, most likely from the detonation of a nuclear weapon in space, would destroy unprotected military and civilian electronics nationwide, blacking out the electric grid and other critical infrastructure for months or years. The staggering human cost of such a catastrophic attack is not difficult to imagine.
