The problem is the Norks have no clue where their missiles will land. :-)

Ghetto people do not have the wherewithal to survive; we all know that. They have no skills and a poor work ethic, and thus cannot even support themselves with day labor.

But “country people”? They are not to be held on a pedestal. I know lots of white trash who live in rural areas, because I am related to them. They are pretty worthless too, and will pose the same threat as urban ghetto dwellers. Like the ghetto dwellers, they won’t be sitting at home quietly starving. No, they will go hunting humans and looting and raping and killing.

I propose we define it further: farmers and those who work the land will have an advantage. Even if they possess a little bit of leftover chemical fertilizer from the previous year, and the ability to put a tiny crop in the ground, that can give them and their family another year.

Folks with good organizational skills and who work well in a team will be more successful than the rebellious lone wolf who thinks he’s hot shit.

People who made the effort to learn survival skills will have a leg up on those that did not. I taught myself how to make water filters out of everyday items, and learned how to make and use activated charcoal for that purpose. It was pretty fun!

People who possess patience will be more successful than those who make rash decisions.

PS: I read that the last mass-produced non-electronic diesel is an early 1990’s Chevy Blazer, and all later models are electronically-controlled. That sucks!

I realize this is “The Internet” where everyone loves their pet fantasies and disregards mundane things like... math, but I did the math for an EMP strike.

No one else, anywhere, has done the math.

So, if you want a math-based perspective (gasp!) instead of wild-eyed thoughts from “The Internet” then let Free Republic be the first to show it off:

A 1 megaton blast at 200,000 km altitude (sweet spot in Ionosphere for EMP effects) would generate ~~ 4.2 *10^15 joules at that point which might translate to ~~ 6.5 Megawatts/200,000 meters on the surface directly beneath the blast, distributed horizon to horizon (~~ 1,200 miles of Earth surface in every direction) so electronics on the surface directly beneath the blast would see an electrical surge from the Hall effect of a magnetic wave passing through conductive surfaces/wire of about 324 watts/square meter.

Obviously the longer length of your wire (circuitry) that is exposed to the EMP the greater your total wattage from the surge will be in your circuit.

Telephone wires could easily spark. Your headlights/taillights might glow bright for a moment, perhaps even pop. Parallel circuits will be less taxed than series circuits.

...but the surge directly below the blast will be orders of magnitude greater than the final EMP that reaches the blast’s 1,200 mile horizon radius (1,931 Km).

Distance matters.

6.5 Megawatts divided by 1,931,000 meters means that the EMP on the end horizon of the blast is only ~~ 3.37 watts per square meter. Pretty much every circuit made can handle that “surge”.

324 watts/sq meter directly under a high-altitude Space EMP blast, trailing down to 3.37 watts/sq meter 1,200 miles horizontally away from the EMP blast.

A nuke in a parked truck in the middle of Manhattan could do some serious damage too.

should be at 200,000 meters not km

The energy from the blast is not that which comprises the EMP. It is electrons knocked loose in the upper atmosphere; and their motion in the Earth's magnetic field which in turn *induces* currents in wiring.

Yes, my numbers above would be at 100% efficiency which isn’t possible in the real world.

Max EMP surge felt on the ground directly beneath the blast will be less than my calculated 324 watts per square meter.

OK, here’s a wargame for y’all:

Missile bloom identified by satellite in DPRK. Two minutes into boost phase, destination is Kansas City.

Attack conference is called. POTUS is presented with the launch authorization codes.

No other inbound tracks.

Question one: Attack DPRK or wait. If attack, provide your attack scenario. If wait:

Warhead lands, explosive charges detonate, no nuclear explosion.

Question two: Warhead is a dud. Provide your response and rationale.

Alternate one: Nuclear detonation 10km west of KC, 8kT, 250 foot wide crater, 500 dead plus livestock, fallout to the NE x 150 miles. Provide your response and rationale.

Alternate two: Nuclear detonation in KC, 100kT, extensive destruction, 50K dead, 200K seriously injured. Provide your response and rationale.

Those giant “fuses” need to be of a specific type in order to respond quickly enough for a HEMP pulse. Most of those fuses are for longer duration pulses - not unlike one’s home fuses. HEMP generated pulses are very quick and these fuses won’t respond quickly enough to protect equipment

There ya go. That is the real concern. However, we do have sensor systems in place to track such a situation.

Kansas City was hit in the 80s you dope! See the missiles coming from the secret silos on the KU campus?! That's Ellsworth Hall in the background ;)

What is it with KCMO always getting nuked. LOL.....Seriesly, though, it IS a primary nuclear target. We build triggering mechanisms for nukes that we ship to Pantex form KCMO (former Richards Gabauer AFB area). Also, nearby is Whiteman AFB, with their estimated 100 B61 nukes.....or none in the WSA.

“The Day After” was a comedy compared to “Threads”.

How a NK attack could turn NORTH KOREA into a nuclear, radioactive wasteland that glows at night.

They try a nuclear attack on the US.

How does one refute nonsense?

Ducks come from Mars. Refute it. I’ll just keep adding endless nonsensical “facts” that add to the story...just like the Internet nerds and their EMP, as with any and all other conspiracy theories.

Whoops: meant to post this:

Ellsworth Hall, Lawrence KS. There is another frame that shows ICBMs launching from Allen Field House and Delta Delta Delta Sorority ;).....90s alum here. Most of my professors were extras in the 83 film. Dumb freshman believed there were secret missile fields around Lawrence.

Actually, many FReepers have nuclear backgrounds. We have command generals, engineers, technicians, missileers, sensor specialists, ANMCC, NMCC, etc.

No one has done the math? Really? You sure about that?

I don't really know, but as President, Trump should have some ideas in the hopper.

I think a quarantine and blockade of NK with nothing going in or out (except via the Chinese border) and a demand to hand over Little Fat Boy for a war crimes trial. You think there's at least a few NORKs with sense enough to not launch a first nuke strike. Very bad public relations blunder to the rest of the world.

I understand that there is much controversy about the actual ramifications of an EMP in the amount of damage that would occur.

But the scary thing about that book, isn’t the EMP attack, but the very realistic scenarios he paints of the breakdown of society should the power grid ever be taken out, no matter how it’s done.

Well, I’ll tell you, the Northeast Blackout of 2003 showed how easily power disruptions can cascade.

The power grid going down is NOT something to be taken lightly.
