Can NK actually launch something HIGHER than the ISS? Then they can’t hit that zone. Then of course there’s the fact that at those kind of ranges, plus having to cut through so much of the ionosphere, EMP will lose most of its effectiveness. The EMP threat is grossly overblown, at best it’s an additional damage circle for low altitude explosions, the super bomb 300 miles up is impractical and will functionally render said bomb useless.
Don't know, but the Russians and Chinese certainly can, along with many others. And it's only a matter of time before NK can - IF they can't now.
I don't think there's any excuse for not hardening our power grid, if not most of our other infrastructures such as anything, or any vulnerable system, key to the well being of the nation.
Problem is, people with the sophistication to launch such an EMP know how to optimize the damage to the US other than that which has been presented.
“The EMP threat is grossly overblown, at best it’s an additional damage circle for low altitude explosions, the super bomb 300 miles up is impractical and will functionally render said bomb useless.”
No blast damage from a 300 mile altitude detonation.....
EMP is real, but how intense and how damaging is not known....
