“You believe some fat kid with a bad haircut and 1970’s technology will kill 90% of us Americans?”
EMP was, FYI, discovered back in the early 1960s. Google “Starfish Prime” to find out the facts.
Here are some other facts: Any nation that can build nuclear weapons, and which can orbit a satellite (the Norks can and have done BOTH), can launch an EMP attack on any location on the entire globe. Also, the technology for enhancing the gamma ray production of a nuclear weapon is not all that sophisticated or difficult to master - if you’ve already got the smarts and equipment to build a nuke in the first place. Get out of your mind the silly and uninformed opinion that a huge (or YUUUUGE) nuclear explosion is necessary to a successful EMP attack. The simple fact is that fission weapons (i.e. A-bombs) are FAR more efficient at producing the types of EMP that would be devastating to a modern society than fusion weapons (i.e. thermo-nuclear devices or H-bombs).
Get informed FIRST, then deliver your skepticism. Until then, you’re just another ignorant victim of normalcy bias.
Yield on Starfish Prime was I think 1.4MT detonated at 400 miles.
The warhead itself was probably a two stage thermonuclear weighing around 10klbs.
Way beyond NK technology.
