(1,976 posts)NK has already launched several satellites into polar orbit. Going over the south pole that go over the Central USA on their first orbit in less than hour after launch.
One of the major concerns is that if they launched an EMP specific nuke on one of these "satellites" that it would be at a height that the single explosion would affect nearly then entire continent. The explosion would not directly blow up anything on the ground but the ElectroMagnetic Pulse (EMP) would be of such an intensity that it would melt down most high voltage power line transformers and just about every electronic device. No power, no internet, and most vehicles and airplanes with computer controls would be toast. I have seen estimates it would take years to repair, and result in tens of millions of deaths from the resulting lack of food and water. More than an actual ground nuke attack.
I know this sounds over the top, but there have been engineers after congress to "harden" the power grid for years but no one in congress wants to spend the $.
It would take someone truly insane and desperate to attack us this way, but Kim Jong Crazy fits the bill pretty well. Especially if Trump wants to poke that hornets nest with a stick.
