North Korea’s Secret Weapon: A Huge Electromagnetic Storm

The diplomatic circuit is awash in optimism as the proposed summitbetween North Korean dictator Kim Jong Un and President Donald Trump draws near. Indeed, Trump is right to go to the table with the North Koreans and negotiate for full denuclearization.
The short burst of vastly powerful electrical and magnetic shocks involved in an EMP could potentially devastate everything from your iPhone to the entire U.S. power grid. Imagine thousands of lightning strikes hitting every home and business in America.
Immediately after the E1 would follow an E2 burst, which is of lesser magnitude and may last as little as a microsecond. Yet these pulses are still able to cause significant damage, in large part because many protection systems will have been wiped out by the E1.
How likely are these scenarios? The idea of either a terrorist group or a rogue state using a high-altitude EMP burst has been seriously examinedby scientific and government groups, but there is no agreement on the potential size of the effect.
Some analysts insist an EMP would not be as apocalyptic as described in the widely referenced 2011 dystopian novel “One Second After,” which portrays an America brought to its knees by such a strike. Others contend that it’s highly unlikely that any hostile power would attempt one, given the overwhelming U.S. nuclear counterstrike that would quickly follow.
Still, even as talks progress, there are military options the U.S. can take simultaneously for a higher level of defense.
First and foremost, we can harden our key systems, beginning with intercontinental ballistic missiles and other nuclear strategic weapons. Next comes vital infrastructure — the electric grid, water supplies, transportation systems, financial and medical networks, and so on. The cost would run to the billions — but probably not the trillions. And it would make us safer not only against rogue nuclear strikes but also EMP effects from huge solar storms, which occur on a regular basis every century or two.
Second, the military needs to increase its ballistic missile defenses against the “single shot” attack that would use EMP. This could include more ground-based interceptors to knock down attacks over the North Pole — a route that North Korea or Iran could attempt. The Navy should plan how it would position its destroyers and cruisers equipped with Aegis combat systems off our coasts in times of rising tension.
Third, the U.S. should be pursuing a variety of advanced systems that can counter long-range missiles through non-kinetic means: lasers (which can be deployed on aircraft or from space); cyber systems that can disable enemy missiles in pre-launch and possibly while airborne; and electronic jamming that can counter cruise missile variants of EMP systems.
Finally, we need to focus more intently on intelligence and early warning systems, primarily based in space, that can detect the movement of launch systems, indications of pre-launch activity, a launch itself, and then track incoming threats. Part of this involves stitching together the various components of the “detect-to-kill chain” in an overarching system that itself is hardened against a preemptive cyber-attack.
We can all hope that the coming spring brings a thaw to U.S.-North Korean relations. But one swallow does not a spring make, as the saying goes — Americans need to be ready for another winter of confrontation if diplomacy does not succeed, and being prepared for EMP is a vital part of doing so.
