North Korea Dreams of Turning Out the Lights Pyongyang doesn’t need a perfect missile. Detonating a nuke above Seoul—or L.A.—would sow chaos. Henry Cooper

Mr. Cooper was the U.S. ambassador to the Defense and Space Talks during the Reagan administration and director of the Strategic Defense Initiative during the George H.W. Bush administration.
Conventional wisdom holds that it will be years before North Korea can credibly threaten the United States with a nuclear attack. Kim Jong Un’s scientists are still testing only low-yield nuclear weapons, the thinking goes, and have yet to place them on ballistic missiles capable of reaching America’s West Coast.
While its technological shortcomings have been well documented, North Korea’s desire to provoke a nuclear conflict with the U.S. should not be minimized or ignored. Pyongyang is surely close to getting it right.
For South Korea the danger is more immediate. According to physicist David Albright, the founder and president of the Institute for Science and International Security, the North Koreans have between 13 and 30 nuclear weapons and can build as many as five more every year. If Mr. Kim were to detonate one of these bombs in the atmosphere 40 miles above Seoul, it could inflict catastrophic damage on South Korea’s electric power grid, leading to a prolonged blackout that could have deadly consequences.
The United States has 28,500 soldiers, sailors, airmen and Marines in South Korea stationed below the 38th parallel—and more at sea nearby. An electromagnetic pulse attack on South Korea could play havoc with America’s ability to mount an effective response to North Korean aggression. One hopes the troops manning the two already-deployed batteries of the Thaad ballistic-missile defense system are prepared for such a scenario (in a concession to China, the newly elected South Korean government suspended this week the deployment of four additional launchers).
In 2001 Congress established a commission to study the danger of an electromagnetic pulse generated by the detonation of a high-altitude nuclear weapon. It concluded that while there would be no blast effects on the ground, critical electricity-dependent infrastructure could be rendered inoperable. The commission’s chairman, William R. Graham, has noted that several Russian generals told the commissioners in 2004 that the designs for a “super EMP nuclear weapon” had been transferred to North Korea.
Pyongyang, the Russian generals reported, was probably only a few years away from developing super EMP capability. According to Peter Vincent Pry, staff director of the congressional EMP commission, a recent North Korean medium-range missile test that was widely reported to have exploded midflight could in fact have been deliberately detonated at an altitude of 40 miles.
