IMHO, this is overly exaggerated neocon scare mongering.
Do we need to better fortify our grid? Yes.
Can NK take it all down with an EMP attack? No, these are the neocon warmonger’s scare tactic.
Remember, they never like a quick and decisive victory — it’s bad for their “business.”
So you admit that the US electronic infrastructure is vulnerable, yet fail to recognize the utterly horrendous consequences of an attack upon our electronic grid? How many of us would survive when the lights, power, water, were instantly cut off, our cars wouldn’t start, and our local grocery store was shut down?
