Seriously, there are some here who believe an EMP attack would be as or more devastating that an actual nuke strike on a city. Utter nonsense as you state.
If you detonate a nuke in the sky, you can blow out the sun.... just like a puff of air blows out a candle.
Since it would be nowhere near a kill shot if the Norks hit us with a EMP it would give us justification to turn them into an ashtray.
