North Korea threatens United States with EMP attack

Published

North Korea may very well have the ability to kill millions of Americans, without directly firing on U.S. soil. For the first time, the pariah country’s state news agency warned it could hit the U.S. with an electromagnetic pulse (EMP) onslaught, a threat that experts contend is both very real and comes with catastrophic consequences.

“The biggest danger would be shorting out of the power grid, especially on the East Coast. Imagine a situation where large sections of the U.S. had no power. Imagine New York or Washington D.C. with no power for just a week. The implications would be hard to fathom,” Harry Kazianis, Director of Defense Studies at the Center for the National Interest, told Fox News. “The casualty rates would be off the charts.”
According to Kazianis, an EMP delivered by a nuclear weapon would not just fry power grids but also carry the destructive power of an atomic device.

“That in it of itself is going to kill thousands if not millions depending on the size of it and where it is dropped. Also, nuclear weapons carry radioactive fallout that would be spread thousands of miles through the atmosphere and oceans,” he continued. “We would be adding to such a casualty count sadly for decades thanks to cancer cases that would arise many years later.”

So how could North Korea pull off an EMP attack? A hydrogen bomb detonated at a high altitude would create an electromagnetic pulse that would knock out key infrastructure – namely prominent parts of the U.S. electrical grid. The higher the bomb’s detonation, the wider the range of destruction. An altitude of just under 250 miles – around the orbit of the International Space Station – would annihilate electronics in majority of the mainland, including parts of neighboring Canada and Mexico, analysts have said. North Korea exhibited its capacity to reach such altitudes in satellite launches in both 2012 and 2016.

An EMP attack, experts warn, doesn’t require definitive guidance systems as the area affected is so widespread.
“An EMP is similar to a lightning strike in some respects, but it acts over a wide area – hundreds of miles,” explained John Gilbert, retired Air Force colonel and senior science fellow with the Center for Arms Control and Nonproliferation in Washington, D.C. “There would be widespread and probably long-lasting power outages and wire-line telecommunications systems such as telephone and TV/internet cable would suffer serious damage. Individual items such as cars and trucks could also be damaged or disabled and damage could occur to electronic devices in homes and businesses.” An attack could cut power to health care facilities and cripple municipal facilities and utilities.

“North Korea consistently exceeds our estimates of what we think they can do, so prudence might indicate we take them at their word,” noted Lieutenant General Wallace Gregson (USMC, Ret.), the former assistant defense secretary, now Senior Director of China and the Pacific at the Center for the National Interest. “The aim is to shut down our electrical grid and all the distribution networks – water, waste, financial, traffic management, air control, radio, computer, others – we depend upon.”
Scientists first discovered the EMP fallout of a hydrogen bomb during a test in 1962, in which lights were burned out in Honolulu – some 1,000 miles from the test location.
Experts have long warned of the plausibility of an EMP attack from the likes of North Korea or Iran. A special task force appointed by Congress and known as the EMP Commission cautioned in 2008 that the largely digitized U.S. could be left black for up to a year as a result of an EMP disruption. They say that even the sensors and monitors that function to re-start electronics after a power outage would be wiped out.
