The government of North Korea has the capability to use an electromagnetic pulse (EMP) weapon to knock out America’s power grid, presidential candidate and US Senator Ted Cruz  (R-Texas) said during the GOP debate February 6.
His comments came when he was asked how he would respond, if he were president, to North Korea test launching a nuclear weapon.
“North Korea wants to launch a satellite, and one of the greatest risks of the satellite is they would place a nuclear device in the satellite,” Cruz  said. “It would orbit around the Earth, and as it got over the United States they would detonate that nuclear weapon and set of what’s called an EMP , or electromagnetic pulse, which could take down the entire electrical grid on the Eastern seaboard, potentially killing millions.”
The exchange was referencing North Korea’s launch of a rocket that its government claimed carried a satellite  into space on February 7. The rocket launch came just a month after the North Koreans claimed to have tested a hydrogen bomb.
“We need to harden the grid to defend ourselves, and we need missile defense to protect ourselves against North Korea,” Cruz said.
