Members of Congress were again warned this week about the threat of an electromagnetic pulse (EMP) attack from North Korea or other rogue entities that could have catastrophic effects on the United States, akin to an extinction-level event.

The briefing was given by two members of the former EMP congressional commission, who said that a nuclear detonation delivered from a missile or satellite could create an EMP which could “shut down the U.S. electric power grid for an indefinite period, leading to the death within a year of up to 90 percent of all Americans.”

Dr. Peter Pry and William Graham of the Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack, established in 2001, have followed the EMP threat closely for many years, and are highlighting North Korea’s recent rapid nuclear missile capability as further proof that the U.S. is behind the curve in preventing a disaster.

In a prepared statement, Dr. Pry wrote:

Just six months ago, most experts thought North Korea’s nuclear arsenal was primitive, some academics claiming it had as few as 6 A-Bombs. Now the intelligence community reportedly estimates North Korea has 60 nuclear weapons.

Just six months ago, most experts thought North Korea’s ICBMs were fake, or if real could not strike the U.S. mainland. Now the intelligence community reportedly estimates North Korea’s ICBMs can strike Denver and Chicago, and perhaps the entire United States.

Just six months ago, most experts thought North Korea was many years away from an H-Bomb. Now it appears North Korea has H-Bombs comparable to sophisticated U.S. two-stage thermonuclear weapons.

Just six months ago, most experts claimed North Korean ICBMs could not miniaturize an A-Bomb or design a reentry vehicle for missile delivery. Now the intelligence community reportedly assesses North Korea has miniaturized nuclear weapons, and has developed reentry vehicles for missile delivery, including by ICBMs that can strike the U.S.”
