The statistics of fearIssues

My mom is always worried about her two sons who live on the opposite side of the nation from her. Before cell phones were common I would return home to find messages like the following on my answering machine (I am paraphrasing):

“Abhi, beta. Please tell me that you aren’t eating beef. You will get Mad Cow disease, you will become a vegetable, then you will die.”

After hearing this message on half a dozen occasions I pretty much gave up beef. Why? Because this is how the messages usually ended:

Promise me beta, ok, love mom, bye.”

Or what about this more recent one on my cell phone:

“Abhi, I heard there are fires all around Los Angeles, be careful, stay away from the hills.” [note: I am nowhere near the hills]

My favorite to date has been:

“Abhi, do you drink water out of plastic bottles that you re-fill? The plastic leaks chemicals into the water. You will die.”

Since the World Trade Center attacks and the terrorist attacks that have followed in other parts of the world (like the recent Mumbai Train attacks), many people have established a new dichotomy in their minds. There was before 9/11 and there is after 9/11. “Everything is different now.” I find such sentiments bordering on delusional but until now I have had no really substantial counter-argument to point to that was any more cogent than me calling the person an “idiot” . That changed this week when John Mueller of Ohio State University published this paper for the Libertarian Cato Institute. Titled, A False Sense of Insecurity? the paper takes a look at how ignorance of statistics allows entities (or my mother) to use fear inappropriately. This article (only five pages) is a must read and something I wish every American was exposed to.

For all the attention it evokes, terrorism actually causes rather little damage and the likelihood that any individual will become a victim in most places is microscopic. Those adept at hyperbole like to proclaim that we live in “the age of terror.” However, while obviously deeply tragic for those directly involved, the number of people worldwide who die as a result of international terrorism is generally only a few hundred a year, tiny compared to the numbers who die in most civil wars or from automobile accidents. In fact, in almost all years, the total number of people worldwide who die at the hands of international terrorists anywhere in the world is not much more than the number who drown in bathtubs in the United States.

Until 2001, far fewer Americans were killed in any grouping of years by all forms of international terrorism than were killed by lightning, and almost none of those terrorist deaths occurred within the United States itself. Even with the September 11 attacks included in the count, the number of Americans killed by international terrorism since the late 1960s (which is when the State Department began counting) is about the same as the number of Americans killed over the same period by lightning, accident-causing deer, or severe allergic reaction to peanuts.

But what about nuclear weapons or other Doomsday scenarios? What if the terrorists get there hands on the really bad stuff that they didn’t have before?

Obviously, this condition could change if international terrorists are able to assemble sufficient weaponry or devise new tactics to kill masses of people, and if they come to do so routinely. That, of course, is the central fear. As during the Cold War, commentators are adept at spinning out elaborate doomsday and worst-case scenarios. However, although not impossible, it would take massive efforts and even more stupendous luck for terrorists regularly to visit substantial destruction upon the United States…

To this point in history, biological weapons have killed almost no one. And the notion that large numbers of people would perish if a small number of chemical weapons were to be set off is highly questionable. Although they can be hugely lethal when released in gas chambers, their effectiveness as weapons has been unimpressive. In World War I, for example, chemical weapons caused less than one percent of the total combat deaths; on average, it took a ton of gas to produce one fatality. In the conclusion to the official British history of the war, chemical weapons are relegated to a footnote that asserts that gas “made war uncomfortable…to no purpose.” A 1993 analysis by the Office of Technology Assessment finds that a terrorist would have to deliver a full ton of Sarin nerve gas perfectly and under absolutely ideal conditions over a heavily populated area to cause between 3,000 and 8,000 deaths — something that would require the near-simultaneous detonation of dozens, even hundreds, of weapons. Under slightly less ideal circumstances — if there were a moderate wind or if the sun were out, for example — the death rate would be only one-tenth as great.

From day one the government has followed a strategy that seeks to cover their liability in case of another attack. Part of the way to do this is to keep people in fear so that if something goes wrong they can be ready with the “I told you so,” instead of making more logical, statistics-based changes.

The shock and tragedy of September 11 does demand a focused and dedicated program to confront international terrorism and to attempt to prevent a repeat. But it seems sensible to suggest that part of this reaction should include an effort by politicians, officials, and the media to inform the public reasonably and realistically about the terrorist context instead of playing into the hands of terrorists by frightening the public. What is needed, as one statistician suggests, is some sort of convincing, coherent, informed, and nuanced answer to a central question: “How worried should I be?” Instead, the message the nation has received so far is, as a Homeland Security official put (or caricatured) it, “Be scared; be very, very scared — but go on with your lives.” Such messages have led many people to develop what Leif Wenar of the University of Sheffield has aptly labeled “a false sense of insecurity.”

The paper goes on to pose three questions that should be part of any probability risk assessment used to help determine the best way to defend ourselves against terrorism:

  • How much should we be willing to pay for a small reduction in probabilities that are already extremely low?
  • How much should we be willing to pay for actions that are primarily reassuring but do little to change the actual risk?
  • How can measures such as strengthening the public health system, which provide much broader benefits than those against terrorism, get the attention they deserve?

And finally the political dimension:

There is no reason to suspect that President Bush’s concern about terrorism is anything but genuine. However, his approval rating did receive the greatest boost for any president in history in September 2001, and it would be politically unnatural for him not to notice. His chief political adviser, Karl Rove, declared last year that the “war” against terrorism will be central to Bush’s reelection campaign. The Democrats, scurrying to keep up, have stumbled all over each other with plans to expend even more of the federal budget on the terrorist threat, such as it is, than President Bush.

This process is hardly new. The preoccupation of the media and of Jimmy Carter’s presidency with the hostages taken by Iran in 1979 to the exclusion of almost everything else may look foolish in retrospect, as Carter’s secretary of state, Cyrus Vance, conceded in his memoirs. But it doubtless appeared to be good politics at the time — Carter’s dismal approval rating soared when the hostages were seized. Similarly, in the 1980s the Reagan administration became fixated on a handful of American hostages held by terrorists in Lebanon. At the time, Reagan’s normally judicious secretary of state, George Shultz, was screaming that we needed desperately to blast somebody somewhere “on a moment’s notice” — even without adequate evidence — in order to avoid looking like the indecisive “Hamlet of nations.” He apparently preferred the King Lear approach. Normally, however, only lunatics and children rail at storms; sensible people invest in umbrellas and lightning rods.

Stop reading my post already. Just go read the whole paper. I can’t wait until my mom calls me tonight. Armed with the correct statistics I shall win the argument for once.

[OT] “Abhi, do you drink water out of plastic bottles that you re-fill? The plastic leaks chemicals into the water. You will die.”

And I thought my mom was the only who said this! What about not cooking in non-stick cookware (causes cancer) or not chewing gum while playing sports (apparently someone who attempted to both at the same time ended up swallowing it, and the piece of gum fell squarely on windpipe, chocking the poor guy to death. If I'm not mistaken, in her version it was a badminton player).

Anyway it's good to know that there are other paranoid ma ke bete out there.[/OT]

Abhi,

This interview with Ian Lustick from UCTV pertains to this paranoia but from a poli sci perspective rather than statistics. A snippet:

I have in the book a quote from a leading official in charge of helping the community of scientists to become involved in the War on Terror, and to change their research, and to apply for grants. I asked this person in front of an audience in 2004 to place the War on Terror on a continuum of seriousness. "If the Manhattan Project were a 10 on a scale of 1 to 10, in which the government knew the Nazis were trying to get a bomb and we wanted to give the scientific community all the resources it needed to solve that problem. That's a 10 -- a super-serious, absolutely real problem and treated seriously by the government as such. On on the other side of the continuum is a 1, where the problem said to exist doesn't exist at all, though it's politically super-convenient to say so -- in other words, 'wag the dog.' In that case there is a war said to be going on when there really is no war." So I asked, on this continuum, where is the War on Terror?" This is a person responsible for helping get people involved in it. "On a scale of 1 to 10, is it near the Manhattan Project or Wag the Dog?" He said, "I can't answer that in public." I asked him in private and he said, "Somewhere between 1 and 1.5." So, it's not as if inside the government what I'm saying is not known, it is just that no one in the bureaucracy can say that publicly. Fighting the War on Terror is now the criterion by which every department has to get more funds, by saying it's important for the War on Terror. And we saw with Katrina, and we saw with the Iraq war, how the top echelons can cook evidence and twist organizations and bureaucracies so that even professionals who have their hearts and their heads in the right places cannot push the country in the right direction.

everyone who is interested in the "misunderstanding" of statistics should check out heuristics and biases, which suggests that the mind is "hardwired" toward interpreting data in a particular way. in fact, there is research which points to the possibility that quantitative scientists who are good at bayesian probability within their own field get really off base once they are outside of their field, implying that intuitive references that are learned are as important as bayes' rule in forming a proper mental model. the scariest stuff, for me at least, was how bad medical doctors are at bayesian probability, since it is an implicit part of diagnosis, test and treatment.

Oh man I love these comments. My mom is a shrink, so every time she hears another case of abuse or bullying, she comes home convinced that her darling son has been similarly abused. I have to convince her that such incidents are generally the exception.

As for the article, I love it but it confirms what I already thought. When I opposed the initial post 9/11 backlash at my upstate New york college, many native new yorkers that were formerly liberals like myself asked me angrily "What I would do about the terrorists that perpetuated this outrage??"

I replied, "Nothing. As far as I can tell, they're all dead. Anyone else caught helping the scheme should be thrown in jail. That's what you do with criminals."

"And what if it happens again?" They countered.

"You deal with it. That's what happens. But the odds of them pulling off something like this again are astronomically low"

I felt it then and I feel it now. When you consider that fifty times more people have died as a result of the subsequent actions taken to "protect freedom", it makes even less numerical sense to keep pursuing the war on terror. I am waiting for the day when US military deaths exceed the number of people lost on 9/11. Perhaps then people will finally get some perspective, since we all know that an American life is worth about 1,000 dark people.

Michael Moore also wrote in Dude, wheres my country? that the chance of falling victim to a terrorist attack in 2001 was less than the frequency of suicides. So in essence, you were a bigger threat to yourself than Al Qaeda. But..., I think its the density that matters, 2000+ people in a span of 1 hour is a lot to inspire fear.

While living life in massive fear of a terrorist attack and thinking about the world in terms of pre and post 9/11 is counterproductive, dismissing the potential severity of a chemical, biological, or radiological attack is equally misguided. VX gas is a hundred times more potent than sarin, and a dirty bomb attack could totally shut down a major city. How do you know what the potential is for a terrorist act in the next month? How do you know we can do little against terrorism? Have you done the analysis?

I guess we should also factor in the 'avoidable factor'. You might be more likely to die in a car accident than in a plane crash, but for most people riding in cars is a necessity while flying in a plane is something which is 'avoidable'.

no. we don't know the atomic unit of economics, all we have to go on are post facto inductive truths (sorry, don't buy the rational actor that much). an analysis of terrorism is possible because we know the atomic unit here, the human mind, and the interlocking higher order social dynamics.

to make it short, the stock market is more complex than terrorist threats, there are more parameters ("threat" is not intent but the ability to use WMDs or something like 9/11).

p.s. if you can't analyze, perhaps we should consult the astrologers?

Have you ever heard of a probability risk assesment? If not you should become familiar with one since that is how a great many decisions in this world (especially engineering decisions that affect you much more significantly than terrorism) are made. Statistics do predict the future well enough for many of the decisions society makes to be based upon them.

We're always a bigger threat to ourselves than anything else, but its about control. Me taking a gun to my temple and letting a 9mm fly through is different that someone else making that choice for me.

Driving is a good example though. We've internalized the risk of getting into an accident not of our doing. Yet, the idea of flying makes people shudder even though it is way safer.

If people are stuck in the body count mode of terrorism, they're making the same mistakes as those in the military and offensive operations against insurgents have done so in the past. Such attacks are tactical in nature that serve a terrorist's strategic purpose. Its about propoganda, power, and dominance. Not the act itself, which is merely a tactic. War on Terrorism is as bad of a phrase as War on Drugs (though I'll be the first to admit having used it as popular reference). War is fought between living entities, not on tactics (terrorism) or materials (drugs).

Razib,

Now you admit that economics is difficult to model because the rational actor theory isn't adequate, but on the other hand you believe we have a complete model of the terrorist mind that will enable us to predict the location and intensity of attacks. Economics is fundamentally the science of human social dynamics.

I did not say it was not possible to analyse potential threats, but merely that statistical analysis is of limited utility.

Abhi,

An engineered system truly is something we know the "atomic unit" of, and hence is susceptible to that kind of analysis.

huh, we don't have a complete model, and we can't predict location and intensity of attacks. i'm not talking a deterministic model here. i'm saying that you used a 'stock market' as an analog and predictivity as a litmus test. i think both are off the track in regards to the comparison with terrorism and a cost vs. benefit analysis. apples & oranges.

in any case, are you a psychic to characterize with such specificity what i believe? back to astrology.


 28 · razib_the_atheist on August 8, 2006 06:00 PM · Direct link · “Quote”(?)

to be precise, the key is to establish the boundary conditions of how terrorists might operate, not exact details of when and where. a big argument about an aggressive war on terror is the potential threat of terrorists, and a probabilistic analysis can give us "reasonable" upward bounds on their destructive capabilities. that's all.


 29 · Gazsi on August 8, 2006 06:03 PM · Direct link · “Quote”(?)


There is no need for a deterministic model. One can tell what the statistical probability is of being struck by lightning at any given point on earth in a given span of time. Or potentially the rise and fall of regional markets.

Why do you keep mentioning astrology? Good intelligence networks and the destruction of potential threats is enough.

Economics is fundamentally the science of human social dynamics.

and just to be precise, economics is an important tool, and the rational actor is an important insight. the problem with many social sciences is that they tend to fixate on one model of human nature ('the rational actor,' or 'class conflict,' etc.) and simply use that to generate the parameters of a model. history, cognitive psychology, sociology, economics, religious studies, genetics, etc. can all play a role in understanding how different groups of humans behave and the range of their potential behavior. unfortunately, this isn't physics, but we beating expectation and going beyond introspection should be our goal.

if one says that something is not analyzable, there is no common ground for discourse, though perhaps someone could put up an interpreative dance which expresses their emotional reaction to potential terrorist threats up on youTube.

Razib,

I would of course love to have the ability to read minds (and over the internets!), but sadly can only respond to what you have written. And you're right, I believe statistics is a powerful and useful tool, when all the parameters are known and measurable, and perhaps in some cases where they are not. My problem is with the thrust of this article, which I believe completely ignores the fact that a cunning and determined enemy can find a way to inflict damage that we probably haven't thought of or have dismissed. Or something. Obviously the chance of me being killed as I go home today is less here than if I were at home in Iraq. But then turning around and saying we should decrease our investment in preventing terrorism based on that lower risk is what I have a problem with.

To this point in history, biological weapons have killed almost no one.

and up until 911 nobody had flown planes into skyscrapers. How to prevent terrorists form obtaining WMD's is the central practical issue of our time, and besides the bush doctrine (from spreading democracy to the 1% rule) there is virtually no comprhensive theory on how to achieve this. even our loyal opposition has been relatively mute, and this from the party that gave us the great unifying theories of the cold war: containment and MADD.

at least meuller admits that this scenario would throw a wrench in his stats, but lamely asserts that "it would take massive efforts and even more stupendous luck for terrorists regularly to visit substantial destruction upon the United States."

But there is no way back to a non nuclear world as humans cannot willingly make themselves ignorant. The cold war solution--where one sides abandons its ideology for the other side's--is really the only long term solution as Bush understands.

And we are not fighting terrorism, we are fighting an ideology. even if terror is not used, those citizens who live in muslim societies (including france) risk losing their freedoms through even democratic means, if this ideology is not defeated.

I agree with that. I think the global jihadist Salafists (who are probably a miniscule percentage of Salafists worldwide) are definitely ideology driven.
In fact, the bombings in Madrid and London came from Al Qaeda inspired independent salafist cells. I fear that the latter will be the norm in decades to come and its going to be much harder to track them down or to prevent them from launching attacks. Of course the independent cells will probably not have the resources (with current technology) to cause too much damage in terms of number of lives. Most centralized Al Qaeda cells like the ones which operate in South East Asia or Afghanistan are probably more lethal but they will eventually get destroyed by the US.

manju, if it was that easy going from design to getting all the materials and implementing the construction of the bomb it seems that we should have long ago been the target of nuclear attack (or someone in the world would have). there isn't a shortage of bitter and desperate terrorists and rebels. my understanding is that design is one thing, but collecting on the materiel and finding the right engineers to build the thing, and then transporting it, are considerably harder. at least for non-states (and even states have a serious problem, elsewise why would iran not have had a nuclear bomb in 1980?).

Sorry, that should have said "nuke design" as Razib pointed out. Some of the actual parts are difficult to machine.

RtA:

manju, if it was that easy going from design to getting all the materials and implementing the construction of the bomb it seems that we should have long ago been the target of nuclear attack

ok. maybe the princeton case is not all it's cracked up to be. but we can only assume it's going to get easier, not harder...especially w/ states working thru private actors (ie iran/hez) or vice versa.

bush's so called 1% doctrine, that the US should treat a 1% chance of a terrorist getting a WMD as a 100% certainty, b/c the consequences are so great if it happens strikes me as a more prudnt policy than meullers, although it is technically a secret policy. how to affect the policy is anothher thing but while meuller addresses the scenario he seems to put his head in a statistical sand.

I'm sure labeling Mueller's paper "irrelevant" feels good though.

OK wolf, i feal bad. it's a well written paper and i think it's worth debating. but i have objections as i stated.

His stats are based on past performance, which as every market watcher knows, is no indication of future performance. He cuts short his discussion of the doomsday scenario w/ a casually dismissive "it would take stupendous luck" line, when this scenario is the whole issue; and he even admits it would change the statistical calculation.

no one, including bush/cheney, is using "irrational fears or gut feelings," though it must feel good to label counter-arguments as such ;-)

There is enough nuclear material/ fuel stolen or unaccounted for (like, former Soviet Union Republics) to make a few dirty bombs. That Princeton guy was a PhD student in doldrums not an undergrad, and he did show that making just a thermonuclear bomb is pretty easy.

Millions of dollars are required only for making weapons-grade nuclear bombs with a robust delivery system and fuel supply. That is another ball-game.

In subconscious level, we do probablistic analysis when we cross a street obeying/ disobeying traffic lights.

Abhi: I was laughing in the background, while you were having that conversation regarding Niles type Virus (in Idaho and few other Western and Mountain States), with your mom just few minutes ago. I think the mainstream media always have some tantalizing topics and try to scare general public with absolutely baseless tidbits. Yo Mom, in-between flipping channels from "Tumhari Disha" and "Sindoor Tere Naam Ka" and God knows what else? just catches few words here and there and calls you and your brother to caution - purely due to love and concern - As other readers substantiate similar behavior by their Moms, she is not the only one who may be paranoid. Being in the NUCLEAR industry for 37 some odd years, and someone who have performed scores of "Probabilistic", as well as "Deterministic" analysis, I can talk about these things for ever. However, may be some other time. It is almost 2100, and as you know well past my bedtime!.....Love..Dad

maybe i was y'all's age when i last penned something called 'statistics of fear'. fresh out of grad school, full of beans, i vented on some article that i thought propagated poor science. i still had it in an old folder so thought i'd share some relevant excerpts.

(railing against...) The sensationalist articles on health-related issues appearing in popular media ... To illustrate, I will dismantle a representative (but fictitious) article – “Study: Eating sugar beets increases risk for colon cancer” – to highlight possible gaps between the research and the reported news.

The strident tone of the headline leads one to believe that the research has discovered an inviolate truth. Digging deeper, one finds the researchers used some thirty people in their study and that their conclusion was based on deviation of the beet eaters from the non-beet eaters in a certain physiological change associated with colon cancer.

The first issue one takes with the reporting is that, at best, the study showed a link between beet consumption and the development of a physiological change that has been correlated to colon cancer – this is distinct from a cause and effect relationship. The second issue is that thirty people are not representative of a couple of billion people around the globe. Exploratory research can not be reported as a lifestyle-altering profundity. In a broader sense, research that bases conclusions on anthropometric measurements and physical appearances fail in the same respects and are junk science. Returning to the beet eaters, another flaw in the interpretation of such research is that the associated “risk” is spread uniformly across the entire population that fits the test criteria. To paraphrase, if there were 10% more people in the beet eating group who developed (say) peculiar growths 10cm in size, the results can not be interpreted as, “everyone who eats beets will develop abnormalities, albeit growths that are only 1cm long”.

Indeed the blame can not be cast upon the journalists alone. The responsibility for accurate news reports rests with the scientists as well. Your example of the researcher who kept discarding his rats until his results suited his hypothesis is a case in point. The inherent flaw with the method of hypothesis testing is that one needs to frame an interesting hypothesis before conducting the experiment. I conjecture that it is the need to justify the investment of time and money that leads otherwise scrupulous scientists to bias their research.

Operational risk quantifiers use tail estimates on large sets of events to characterize the loss due to terrorism etc. I know a few people in and around the Northeast that work in these areas -- mostly for banks and large insurers. The point of the exercise though, in most such cases, is merely to find out how bad things might get in the event of something catastrophic (including the avian flu). Only recently have people begun looking at how transnational supply chains can be modified (or made more robust) to prevent supply shortages in critical situations.

Academically inclined minds might want to check out Dick Larson's page at MIT to know more about the latest in disaster management. An interesting related article from MIT again was by Yossi Sheffi on evacuation and emergency logistics in the context of the bombings in southern Lebanon.

However, note that none of these approaches actually look at "ways" to mitigate the cause itself. Well, to be honest, that is perhaps beyond the ambit of a mere operations researcher.

I am yet to see a good blue print on how to detect independent cells of the Madrid, London bombers type.

Very difficult in the case of the latter, although there have been ongoing efforts by the British security services and I believe 3 post-7/7 attacks have been foiled. There is also a trial of 7 British-born wannabe jihadists underway in London as you may be aware -- they wanted to blow up nightclubs, attack energy grids etc.

The problem is that a virulently anti-Western mentality is not necessarily being encouraged within mosques in the West (apart from examples such as Finsbury Mosque) but "backroom" cells -- basically ordinary people watching jihadist propaganda videos in other people's houses etc. Apart from secretly monitoring communication between such people (bugging cars/homes, observing jihadis internet chatrooms etc) and tracking travel to and from Pakistan and the Middle East, actively monitoring and predicting potential terrorists is like trying to "track" and predict racism. It's the ideology which is the primary problem, perpetuated extensively by "regular folk". The fact that many older-generation Muslims (indeed, older-generation South Asians in general) have such a virulently anti-Western and (with regards to white people) racist mentality, partly fuelled by the grudge about colonial times, probably doesn't help matters either. We all know how many older desis talk when white people are not around.

Something we've all discussed before here on SM is the fact that, in recent years, Saudi funding of British mosques has been a driver behing the shift from "subcontinental" Islam to a more hardline and conservative Middle Eastern interpretation of the faith (check out a link on the News tab called "What Muslims Want", for example -- large numbers of 2nd-generation Muslims in the UK are more strictly religious and more conservative than their parents). So, finding a way to sever that funding may be a partial solution. A disproportionate number of the problematic Imams here in the UK, for example, have turned to be not South Asian but Middle-Eastern, who have been encouraging both an anti-Western mindset amongst their predominantly-but-not-exclusively South Asian Muslim followers and a "return to pure, Arabian Islam" ethos.


 58 · Jai on August 9, 2006 06:35 AM · Direct link · “Quote”(?)

With regards to the global situation as a whole, however, it's a very difficult issue. Some amateur suggestions by myself:

1. Target Saudi political and religious leadership. They need to withdraw their support for any religious interpretation which encourages false grievances and an unjustified adversarial attitude against the non-Muslim world. Difficult, considering the historical "deal" between the House of Saud and the Wahabbists.

2. Target the leadership of the terrorist groups concerned and try to persuade them to change their minds about both their notions of spirituality and their alleged grievances against the West (and non-Muslim countries). Much easier said than done, of course, but there are historical precedents for this, even though the struggle was long, bloody, at huge cost, and with no guarantee of ultimate success.

3. Attempt to encourage a concerted, organised, worldwide campaign by Islamic religious authorities to debunk OBL/Al-Qaeda and their interpretation of Islam. Of course, the really hardcore jihadists will not care about this and will try to "turn the tables" by claiming that the debunkers themselves are misguided and heretics. However, if the problematic individuals and organisations are explicitly condemned as outlaws and heretical, blasphemous outcastes from the perspective of Islam, then that would perhaps go some way towards undermining support for them along with, possibly, enabling the "Ummah" itself to target and pursue them and thereby solve the problem internally.

4. The "nuclear option", if all of the above fail, is to supply enough inalienable academic & historical evidence to debunk the religion itself. Not a nice thing to do, as it will alienate neutral/moderate Muslims everywhere, along with confirming the terrorists' claims of a "War against Islam", and in any case the really crazy types will ignore any tangible, verifiable facts presented to them anyway.

cold war solution--where one sides abandons its ideology for the other side's

I partially agree, although I don't think it's necessarily an "either/or" situation -- the "other side" doesn't necessarily have to embrace "the secular western societal/cultural model" in its entirety, they just have to modify their interpretation & practice of their theology/ideology, or find another more compatible faith if an atheistic/agnostic vacuum is not desired. Obviously difficult (although not impossible -- again there are historical precedents for this), considering the "internal locks & safeguards" within orthodox Islam with regards to apostasy/conversion, along with modification/reinterpretation of the faith's tenets.

However, note that none of these approaches actually look at "ways" to mitigate the cause itself.

.....Which is the crux of the problem. Defending oneself against the "symptoms" is one thing (reactively or pre-emptively), but attacking the root cause is another.

In my life, it's not my mother that acts like this (she's very laid back and calm about things), but my mother-in-law, who lives with us. Everything is a portent of doom or on the verge of killing us: "Don't sleep with the air conditioning on, it will give you pneumonia!", "That rattling near my tires probably means I'll need to replace the entire engine!", "If you buy online at Amazon they'll steal your credit card information and buy themselves boats with your money!", "You need to cook your pork to 180 degrees or you'll die!".

I just kind of nod my head and keep doing what I'm doing. No sense in angering my Mother-in-law because it ends up angering my wife.

Some articles about this were posted in the News tab too a few months ago. Here's a detailed article from the BBC News website.

Chilling stuff, especially as all of the accused are British.

Thanks for the article. Its really very depressing. I fear that the current and future conflicts in the Middle East will just add fuel to this fire.
I went to school in UK and was impressed by how mainstream is the profile of desis in UK. At the same time, I was appalled by the desi ghettos (mostly pakistani) and the poverty, unemployment, religious conservatism in some of those areas. You really dont see that in the Desi Muslim communities in the US.

AlMfD,

You're absolutely right about the state of affairs here in the UK -- it's been wreaking havoc in the country as a whole (7/7 being the most obvious example) along with having serious repercussions for South Asians of all backgrounds in general.

You might also find it informative to check out the "What Muslims Want" article in the News tab (date: August 8, 2006), along with the related link to the ongoing discussion on Pickled Politics. There was basically a wide-ranging survey here in the UK about British Muslim attitudes on a variety of issues, followed up by a high-profile programme to discuss the findings on one of the main terrestrial British channels a few days ago.

I don't know what the Princeton student actually designed, but the Nagasaki bomb actually had a 21-kiloton yield and was far more complex; it had a plutonium core, which requires a little more ingenuity to detonate. The Hiroshima bomb used enriched uranium, the most easily available source for terrorists, I would imagine. A uranium bomb is EXTREMELY basic in construction, so basic that no one felt any need to test it before dropping it on Hiroshima (the Trinity test was of the plutonium bomb). It works like this: Take two sub-critical masses. Put them about 1 meter apart, say at opposite ends of a cannon. Fire one towards the other at gun velocities with whatever explosives. When they collide they will form a critical mass; chain reaction and a nuclear explosion will result. Presto. I could probably build this in my basement in a month or two (although the risk of blowing myself and half of my city up is obviously great). Now I just need to find some enriched uranium. Oh, wait... it's nearly impossible to get ahold of enriched uranium!

I wouldn't bet on that assumption...

Britain's reprocessing plant at Dounreay was shut down on 2 December because 10 kilograms of highly enriched uranium (HEU) was found to be missing during a routine inspection.Link

International nuclear inspectors, already troubled by the disappearance of bomb-grade uranium from an ex-Soviet institute, want answers to an even more disturbing question: Has any equipment that makes such material disappeared as well?Link

A quick google search on "missing enriched uranium" shows a bunch of articles. And that's only what the authorities are publically admitting I'm sure.

Everyone, a massive terror plot to blow up 10 passenger jets mid-flight from the UK to America has just been foiled. 21 people have been arrested in the UK and most of the wannabe jihadists are unfortunately of South Asian (specifically Pakistani) origin, although they're all British citizens. It's causing chaos at Heathrow Airport along with impacting flights and airports worldwide.

I've posted a couple of "Breaking News" articles on the News tab, so please check them out for further information.

Seems like my conversation with AlMfD yesterday was terribly prescient.
