I still see a cyber attack on the grid as having a higher probability, but that doesn’t mean NK wouldn’t try to do an EMP. Even if he was only able to pull off a small one impacting just one part of the country, it would still have massive nationwide repercussions, and likely worldwide repercussions. WWIII will have begun. He may be too crazy to comprehend this but the big boys (Russia/China) are anything but crazy. They know that no matter what happens to the continental US, each of our ballistic missile subs are capable of destroying any country or set of countries they choose.
