I really wanted to talk about this topic first, as it drives any planning or preparation. I suppose it’s part of human nature to obsess about the end of the world, and to scare yourself silly worrying about all kinds of threats to civilization. Some are mose likely than others to suffer from it, but most people think about from time to time. Let’s list them, according to current popularity:
EMP
Definitely the top concern of many preppers, and many ignorant government officials. EMP is short for ElectroMagnetic Pulse, a previously obscure nuclear weapon side effect that has gotten plenty of press as the existential threat to humanity. I won’t dwell on the basics, but EMP is produced by any nuclear blast and is maximized by detonation in the upper atmosphere. It creates an electrical surge that can damage wires and electrical devices over a wide area. It is a real effect, and is a concern but tends to be overrated in terms of the actual effects and likelyhood. So how would this happen in the first place?
Terrorists
According to popular thought, terrorists obtain a warhead and somehow manage to get it optimally postioned over the US midwest at 200,000 ft and set it off. This creates a large EMP event that destroys all power distribution systems and electric devices in the country. No power, no spares, no way to bring the grid back and the SHTF.
Problems with the theory
- Getting a device over the US without NORAD (or whatever the new acronym is) noticing. There are only a few ways to get a warhead to 200,000 ft; ballistic missile, air launch, or inside a satellite. All are tracked by radar nets, and all can be intercepted with current and projected missile defenses. You can bet Sammy is watching all of these very carefully, as there are X-band systems in place to do this. It’s been sort of quiet, but I see notices of deployment of THAAD and the other systems to cover CONUS. So just attempting this has a low probablity of success, IF the Air Force has a reasonable shootdown policy.
- Achieving crippling damage with a single device. From what’s publically available, the effects of a single burst are highly dependent on yield, height, weapon design, and most importantly the vulnerablity of the electrical/electronic systems. Fiction has every electric thing in the entire country fried, but reality would different. No one really knows what damage would be incurred, but it’s a safe bet that many devices would survive, or be repairable following the event. Bottom line is no one really knows how effective this type of attack would be, due to the difficulty in modelling it. It’s impossible to test it, obviously, and designs are getting better because of European electrical immunity requirements. Lighting used to take out a lot more stuff, but burying power lines and including ESD/bypassing has improved that. People are resourceful and would be working their ass off putting thing back on line, and yes there would be parts.
- Death Wish, anyone? Strategic assets would survive (missile silos, aircraft, subs, ships) and would leave full retaliatory capability in place, and it’s a fair assumption we would find out the source of the attack. This event would be a nuclear attack on the US, and I doubt any constraints would be in place as far as responding. No one would be marching around protesting US foreign policy afterwards, it would be Full Hammer Time.
Point 3 assumes the Rational Man theory is in place, but that may not be relevant. Consider Pearl Harbor, 911, Korea, the invasion of Russia, and Gulf War 1/2. These all fall into the “what where they thinking?” category, so maybe we can’t rely on getting killed as a deterrent. But even so, barring a full scale laydown attack by a major power EMP is either less likely or not as horrible as portrayed.
Attack by a major power
A way EMP could be really bad is if an enemy does a Cold War special and launches enough specially designed weapons to overcome BMD and blanket the US with very high levels (>200,000 volts/meter) of EMP. But we’d all have bigger things to worry about at that point….as in a full-scale exchange (see nuclear war).
So I give this a low probability of occuring, and not worth installing EMP hardening on your house, bunker, or stored assets.
Zombies
Yes, really. There are people who actually believe zombies will appear after some unspecified infection and will roam the earth in search of food. I blame the movie industry for this, and not worthy of further comment.
Economic collapse
This rivals EMP as the primary raison d’etre of preppers. I haven’t given this any thought specifically, as it falls into the general emergency category. I suppose it could happen, and if it did it would put a lot more importance on long range planning. Assuming some economic collapse occured, it would tend to play out over months and years and create the need for near total self-sufficiency. This is a lot different from the usual prepper creed of “got my year’s supply of guns, gold coins, and beef jerky”. Given the latest news on Greece, Portugal, and Spain, plus the open season on the value of the dollar by the Fed, I’m giving this a higher probablity that I normally would in better times. Still, collapse? Man that’s hard to imagine.
Civil Unrest
This could be a consequence of economic collapse, as it’s hard to imagine anything else motivating people to leave their homes and go on a massive nation-wide crime spree. Would things ever get bad enough to have widespread civil unrest in the US? Given the number of privately held firearms it would tend to be limited. Most people in the suburbs and rural areas would bust out the gun collection and keep the riff raff at bay, but cities may be at risk.
Natural Disaster
See Civil Unrest, but this one is more likely especially in a region versus the entire country. Remember Katrina? I’ll reference this later, but it showed on a very small scale what SHTF looks like.
Pandemic
This is the original reason I got re-interested in preparedness. Recall the H5N1 scare of 2004/5, this has a VERY real chance of occuring. It hasn’t gotten much press recently, but we have the 2009 H1N1 event as a sample of what’s in store should a pandemic break out. It’s interesting how a pandemic doesn’t have to be particularly lethal to cause a major disruption in our lives, just bad enough to keep people from going to work. No workers, no services and things grind to a halt until it subsides or people get over their fear.
Nuclear War
The original SHTF Classic. Regardless of what the peaceniks say, the threat of a nuclear war is not zero. Getting rid of our arsenal may actually make it more likely, given the advances in BMD. I won’t spend a lot of time talking about it here, but there are a number of ways an exchange could occur:
- Intentional launch by a minor power (think Pakistan) against a local rival
- Accidental launch by a major power (including rogue elements in the military)
- Intentional attack by a major power
This plays out as bad to very bad, since the outcome is at best radioactive fallout/global cooling and at worse the levelleling of all major cities and wide areas of intense radioactivity.
I give this a low probablity of occurance, see EMP.
Volcano eruption/Asteroid strike/Gamma burst
I included this just for completeness. It’s in the Natural Disaster section, but could happen. Very low probablity.
