Former Crypto-Analyst Analyzes the Danger of Nuclear Weapon Stockpiles

An anonymous reader writes "IEEE Spectrum reports that noted encryption pioneer Prof. Martin Hellman has a new passion; estimating the risk of our current nuclear weapons policies. His web site, Defusing the Nuclear Threat, asks the question, 'How risky are nuclear weapons? Amazingly, no one seems to know.' Hellman therefore did a preliminary analysis and found the risk to be 'equivalent to having your home surrounded by thousands of nuclear power plants.' The web site and a related statement therefore urgently call for more detailed studies to either confirm or correct his startling conclusion. The statement has been signed by seven notable individuals including former NSA Director Adm. Bobby R. Inman and two Nobel Laureates."

A smaller offensive measure would be used for retaliation, but not with the intention of assured destruction. The small force would be used to strike back and wear the enemy down over repeated attacks since a defense-centric policy will allow enemies to launched repeated strikes knowing the counter attack will not be large. The goal of the defense-centric policy would be economic control of resources. Eventually the enemy will no longer be able to sustain an offense, in which the small counter force can now entirley destroy the enemy.

      Removing the 'Mutual' from Mutually Assured Destruction greatly increases the chances of nuclear war. If your enemy has no defense against your nukes, then the temptation for you to use your nukes increases dramatically. Meanwhile, your enemy isn't stupid and realizes that he will be at your mercy once your defense is implemented.

      You need to open your mind and think about it from the enemy's point of view. Your enemy can:
      a) build his own missile shield before you finish yours
      b) figure out how to defeat the missile shield before it goes live,
      c) attack before the missile shield is live,
      d) trust that you'll be nice enough to not attack, bully, or force political and economic concessions from your position of superiority.

      A is too expensive for the Russians.

      B is either too expensive, or inherently destabilizing. Russia could put subs closer to the US but that would reduce an already short warning time, thus increasing the chances of a mistake triggering nuclear annihilation. Or they could develop stealth missiles/bombers. Or they figure out how to smuggle nukes into the country, which cuts the warning time to zero.

      C, attack now, is very tempting. You simply state that you will launch before the missile shield goes live. Under MAD, bluffing is not a winning strategy. If the US backs down, we lose face but nobody loses. If we don't back down, then Russia has to do _something_ or it loses. Which means they must launch.

      D, trust your enemy, isn't likely. Even if you're 99% sure that the US wouldn't launch, can you guarantee that the US won't use its advantage to rape you economically and politically? Can you guarantee that the US government will remain stable long enough to not nuke you until you can achieve parity again? (civil war? economic collapse? coup? police sate? religious fundamentalism? pride? stupidity?)

      A counter argument is that the longer we have nukes pointed at each other, the chances of a mistake occurring approach near certainty. However, if the US is immune to Russian nukes, then we're likely to become less concerned about making mistakes ourselves, thereby increasing the chances of mistakes. (Why continue to put a lot of money and attention into something that won't affect you?)

      Thus, taking the Mutual out of Mutually Assured Destruction is almost guaranteed to start a nuclear war.

      So the only practical solution is to build a small scale missile defense shield designed to stop a small number of launches, while you figure out a safer way to defeat your enemies or otherwise provide security for your nation. The economic collapse of the USSR is one example. Converting your former enemies is another way (such as extending NATO membership to former Warsaw Pact countries.) But a full scale missile defense right now is just asking for MAD.

      This is our defense strategy as opposed to focusing on efforts to block or dodge a punch.

    There is an article in April Scientific American which exposes the twin facts that no screening currently exists that can detect significant amounts of weapons grade Uranium being brought into the US or Europe in shipping containers, and that the amount of weapons grade U on the loose is enough to make home made kiloton weapons possible. Although the article only cites public data, there are an awful lot of physicists and engineers about who could design a simple low yield nuclear device given access to enough enriched uranium.

    I also wonder if the murder of the ex-KGB agent using polonium was a covert warning - because, of course, if you have access to enough polonium you can made a gadget to trigger a plutonium weapon, which can be quite small and, even if it fails to create a fission explosion, has enough HE to spread radioactives over a large area.

    Our desire for cheap international trade based around largely uninspected shipping containers exposes us to an enormous risk.If all shipped goods had to be properly inspected at point of entry, trade would suffer a bit, it would be less attractive to make things cheaply in China or Thailand, but a huge hole in the security system would be fixed. It's ridiculous that air travelers are inspected at vast inconvenience and expense when it is literally possible to import a bomb's worth of uranium or plutonium with no real checks at all.

      I find this is the key difference between Real World security and computer security. In computer security, weaknesses, once known, _will_ be exploited on a massive scale. In the Real World, things are often far less grave. This explains both why so few people get computer security right (applying a Real World "it will be ok" attitude to computer security is a mistake), and why I think people should just relax and not worry so much about, for example, terrorists blowing up airplanes.

      Security should, at least in my opinion, always be a cost-benefit trade-off. More severe security measures can reduce the risk of a disastrous security breach, but security measures incur their own cost, which you pay every day, even if no security breach is even attempted. The trick is finding the right balance.

      Your impression of things being alright does not constitute a fact. It's merely an impression. Real world security is very much like computer security: how you feel about security has little or no relation to how secure you are. Hellman knows this.

      The US has used this knowledge to great advantage using propaganda at various times in its history. The anti communist-propaganda in the fifties was a great example. So was the weapons of mass destruction campaign just a few years ago. In both cases the aim was to spread panic in order to do what was perceived as necessary to protect the oil business. Given the oil prices today, this was probably misguided. As was the rest of that war.

      The US government also uses this tool in the opposite way. Major incidents are routinely played down or not reported at all. Or when they are reported the facts are misrepresented. This creates a false sense of security. For example, US marines getting blown up in Iraq on a daily basis was kind of hard to keep out of the news but you can always try to give a positive swing to it and try to keep the pictures of the flag covered coffins out of the news. Like everything George Bush does, he botched that as well since the pictures got out.

      So now the issue is that both the US and Russia have been providing nuclear technology to various unstable regions such as Israel, Taiwan (oops sorry for sending those detonators, yeah right), Pakistan, India, Iran, North Korea and maybe a few others. Luckily, Reagan only sent Stinger missiles to his buddy Bin Laden in Afghanistan in the eighties.

      So, I find the theory that the probability of one of the powers that be in such regions hitting the big red button is much worse than once in a million years to be quite credible at face value. The big question is just how bad things are. I'm hoping the rest of the world is not so trigger happy when it happens but the probability for that might be such that the event is quite likely to happen. Another possibility is of course that at some point somebody repeats the Manhattan project by putting all the little pieces of the puzzle together or by stealing & acquiring the necessary information. This is roughly how Pakistan became a nuclear power.

      So I don't care so much about how you feel about it. Probably for the economy it is actually best if you and most other people are blissfully ignorant. But on the other hand a little recession is a small price to pay for some good quality protection. All I know is that some smart guy that seems to have done a lot of homework seems to be pointing out that facts are pointing towards likely escalation to full nuclear war.

That distance leads to inefficiency with resistive losses over the power lines. The greater the distance, the bigger the loss. And the more current you try to push over those lines, the loss goes up by the square of the current.

"Some could argue with the numbers he used, but he does give logical reasons for using those numbers and admits that they have large uncertainties since the events have been rare in the past."

    Robert N. Charette, who runs the risk-management consultancy ITABHI and is a regular contributor to IEEE Spectrum, agrees with Hines. However, he says Hellman should have also turned the analysis on its head. "The other side of the risk equation is, suppose you get rid of nuclear weapons. Does that increase the probability of war?

Perhaps there is also a new weapons program in Russia but it just hasn't got anything in the press yet.

The Department of Energy (DOE) has admitted that, "economic viability for a nuclear plant is difficult to demonstrate."

Plants with good safety systems and procedures still have accidents, but few to no people are killed. Look at the history of nuclear power accidents and you'll see that almost all of them are like this. A reactor goes critical, but is contained. A worker doesn't follow procedure when replacing a part -- he's killed, but nobody else is.

When we lived in Southern California in the 1950's, I can remember the AEC announcing A-tests and putting directions to the public parking area in the papers, and if the wind shifted they blasted away anyway!

I recall a book there written by the former head of AEC security who stated the Soviets had not made a bomb of their own prior to 1954 except that they had stolen material and or bombs from the US. Given that we used to have prototypes of the latest Soviet tanks and airplanes undergoing testing at various government proving grounds at the time that seems pretty credible (they used to fly the brand new MIG-21, not yet operational in the Soviet Air Force, out of an air base in San Antonio, where we lived, and the newspapers and TV stations were "discreet"). I used to read a lot of heavy literature on MAD, etc., and one of my favorite remembrances of the literature of that era was a parody of the captain of the Titanic which began: "If struck by an iceberg - we would never strike first -....."

The supposed response of the Israelis was to line up their nukes next to attack aircraft for the next overflight of a Russian satellite.

For the next week, all the papers and TV news reports, and I mean all of them, showed pictures of groups of unhappy bored Soviet soldiers still on their bases. In fact, they never left their bases until they returned to the former Soviet Union. Stories were that the Soviets had been given a message about what would happen if the soldiers ever left their barracks. The bizarre staged photos of the troops "still on their bases" seems to support this.

    My point of the three previous comments is that there has probably been a long history of nuclear weapons and nuclear materials escaping from proper command and control - probably literally from the days of the Manhattan Project. The remote detection capabilities of 35 years ago means that any re-assurances that there are no nuclear materials unaccounted for should not be in the least reassuring!!!

I am nowadays, much more concerned about other things. I would be the first to admit that a terrorist use of a nuke is a high probability, but there is virtually zero chance that such an event would lead to a global nuclear war.

    The experience of the first 50 years CANNOT be extended into the future. Those first 50 years were very different animals. We were poised in a 'mexican standoff' with a superpower enemy possessing a vast nuclear arsenal that feared and hated us. We no longer have such a superpower enemy. Even if Russia started to hate us the way the Soviet Union used to, they are no longer a superpower, they are a pale shadow of what the Soviet Union once was. Their existing arsenal is so old and unmaintained, most of their missiles wouldn't launch and the warheads wouldn't detonate. Most of their weapons are no longer in service. They maintain enough to serve as a deterrent against a nuclear attack by an opposing nation, but that is it. They cannot wage nuclear war.

    There is only one nuclear war fighting capable nation on earth right now and that is the US. The US is not about to fight a nuclear war with itself. No other nation will use nukes against the US, unless their very existence was at stake and the US knows to not attack nations that could ship a bomb to us in a shipping crate. Global nuclear war requires two opponents both possessing a nuclear war fighting capacity. Deterrent forces alone are not sufficient for anything other than deterring the other guy from attacking. In order to strike first, you need a 'first strike' capacity, the idea that you have sufficient weapons to knock out with your first strike, the other guy's ability to strike back. Only the US has this capacity.

    From the article:
    "Because this estimate is based on a simplified, time invariant model, it does not apply to the current point in time when relations between the U.S. and Russia are significantly better than they were, on average, during the last 50 years. However that does not invalidate its conclusions."

    Er, yes it does invalidate its conclusions. Obviously. The author suggests that the time may come when US/Russian relations deteriorate and asserts that this would then recreate the old situation. However Russia is no longer a superpower and could never again challenge the US in this regard. The Chinese could in theory build up to challenge the US in a new nuclear stalemate however and if China ever starts to build up it's nuclear forces, we would then have cause to worry. However we would likely see evidence of that sort of a buildup long before the threat matured and hopefully could take diplomatic action to change the situation.

    Note also that China does not need to challenge the US with nukes. They hold a very effective deterrent against US aggression by the quantity of US dollars they hold in their reserve. If they were to ever dump those dollars into the global finance system, it would create a domino effect on the US dollar that would utterly crash the US economy. Both China and the US authorities know this.

    As a total aside; a missile shield in the hands of the US could invalidate the deterrent forces of those nations possessing them. The US in theory could launch a disarming first strike against a nation and then use it's missile shield to shoot down the few missiles the disarming strike missed. This would result in the US being able to initiate a nuclear strike with impunity, even against a nation possessing a nuclear deterrent force. This is why a missile shield is opposed by most nations. In reality of course, such a disarming first strike could not be sure of stopping the shipping crate nukes that likely would be coming in retaliation.

The model was used to investigate the effects of a war involving the entire current global nuclear arsenal, projected to release about 150 Tg of smoke into the atmosphere (1 Tg is equal to 1012 grams), as well as a war involving about one third of the current nuclear arsenal, projected to release about 50 Tg of smoke. In the 150 Tg case they found that:

            A global average surface cooling of -7C to -8C persists for years, and after a decade the cooling is still -4C (Fig. 2). Considering that the global average cooling at the depth of the last ice age 18,000 yr ago was about -5C, this would be a climate change unprecedented in speed and amplitude in the history of the human race. The temperature changes are largest over land ... Cooling of more than -20C occurs over large areas of North America and of more than -30C over much of Eurasia, including all agricultural regions.

  39. Re:Krakatoa only 200mt by Anonymous Coward · · Score: 0

    Actually, krakatoa was only about 200 megatons so it would only take about 10 groundburst detonations, assuming our most powerful 20MT H-bombs to equal that. Of course, the average warhead on an ICBM is smaller than that, usually around 300KT. Assuming an average of 1MT per missile due to multiple warheads, we would be well beyond Krakatoa levels in any kind of nuclear war. Also keep in mind that krakatoa did reduce the amount of sunlight by a fair bit, though not for that long.

  40. Richard Garwin is, uh, WHO? by dsmall · · Score: 2, Insightful


    I am quite annoyed at the incredible sloppiness at the IEEE site.

    I quote from their site thus:

    "Hellman has set up a Web site related to his nuclear deterrence work. From there you can download the Bent article. You can also view a statement signed by Richard L. Garwin, who came up with the design for the first hydrogen bomb;..."

    Where IEEE dreamed this ... whopper ... up is beyond me, especially now that most of the classification barriers are down and the truth is widely known. This goes into the "bonehead" mistake bin.

    First hydrogen bomb was the Teller-Ulam design, who share the patent, tested Nov 1, 1952, yield 10.4 MT, codename 'Mike'. The history of that design is pretty well known (for example, see Rhodes, 'Dark Sun'). Things were very stuck around 1950. The 'Classical' H-bomb design did not work according to computer simulation. So things sat in 1950.

    Then, suddenly, something new: Stan Ulam pointed an new idea out to Teller, and Teller came up with another idea, and it was a *staged* approach, "technically sweet" (as Oppy put it). Mar 9, 1951, a paper with the first half was published (quite classified). Within a month, Teller thought of the second critical part. (Rhodes, pp. 776). Suddenly everyone thought there was a legitimate chance. There was high activity work leading to a full scale test in late 1952. It worked.

    Now, where is 'Inventor Garwin'? He is not even in the index of Rhodes' book. (!!)

    But from fas.org, looking up Garwin, I see: "He received the B.S. in Physics from Case Institute of Technology, Cleveland, in 1947, and the Ph.D. in Physics from the University of Chicago in 1949." and "After three years on the faculty of the University of Chicago, he joined IBM Corporation in 1952, ..."

    Ahh, I see. He got his Ph.D. in Physics, presumably while secretly helping Los Alamos, and joined the U of Chicago, where he sneaked ideas to Stanislav Ulam and Edward Teller across the desk, as it were, you know, down the hall, a mere thousand miles away.

    I've usually found that on nearly anything, when they can't get the basics right, there are serious flaws in the rest. And yes -- there are serious flaws, as to be expected.

    Quick example: tritium. United States weapons are designed to use tritium as a booster in the primary stage. The trouble is, tritium is radioactive, and has a 12 year half-life. It goes bad quickly, in other words. Try to fire a nuke whose tritium has been sitting around for, oh, 24 years (two half lives), and you may get yourself a fizzle yield. This is called "embarrassing", especially if you didn't get a warranty on that nuke from Nukes 'R 'Us.

    At Pantex, in near Amarillo, TX, where we are disassembling nukes to keep up with treaty obligations, the last I read was that we were tearing down 3 warheads to gather enough tritium to refill 1. This means there are, well, boneyards full of nukes that ... just don't work, but somehow get counted as active ... if they make the report more scary.

    I generally find that people who are trying to scare a new "We're All Gonna Die In 20 Years" movement up never think of the tedious reality of these things.

    I'm an older guy.

    I remember the scare tactics.

  41. The problem with deterrents by jandersen · · Score: 1

    A deterrent is, basically, a threat. The problem with threatening other people is that you may end up in a situation where you have to carry out your threat. One can only speculate whether the cold war could have been avoided, but if we want world peace at some point in the future, we have to work towards reducing the level of threats globally. This may be a scary prospect for some, but at the end of the day, it is the only way. The US likes to see itself as 'the leader of the free world' - do you guys have the courage to lead the way towards world peace?
