Ok, I've read that part, but what it does not mention other than saying that one could cause an EMP "over a large geographic region".  By using those words they imply that it could be any large area.  They did not imply that "One" bomb would cause the whole of the USA to become disabled, which is what the mainstream media is portraying it as.  I still hold to my original comment.  It take multiple warheads to totally disable the United States.
A problem arises from the statement of Russian EMP experts saying they accidentally gave NK their EMP plans, (for lack of a better word), which also included Pakistan and China I believe.  Now that may be a problem, especially if they also were afforded the plans for the Soviet Scalar/Kinetic weapons as well.
