CBRN Weapons and Non-State Actors

What type(s) of non-state actors, according to their characteristics and objectives, are most likely to use CBRN weapons? by Amaury Vergely 

Ever since the 1995 sarin attack of the Tokyo Subway by the religious cult Aum Shinrikyo (“Aum Supreme Truth”), there has been a growing fear that non-state actors, especially terrorist groups, might decide to resort to Chemical, Biological, Radiological and Nuclear weapons (CBRN) on a large scale. Governments and counter-terrorism agencies have set up measures to minimize the threat, while academics and experts have tried to profile the groups interested in acquiring and using such weapons. First of all, it is important to explain why this paper will deliberately focus on terrorist groups, which are only one sub-category of non-state actors (other groups would include political lobbies, criminal organisations, separatist groups or even single individuals). When it comes to CBRN weapons, this paper argues that any group willing to use them could be defined as a terrorist organisation (but not automatically, insofar as “terrorist” remains a label that does not have a globally shared definition), whatever its personal objectives or characteristics. Indeed, although CBRN weapons can be very different from one another, they share some key aspects that make them all identifiable as “terror weapons” (their ability to provoke mass destruction and generate unprecedented fear among the population, to name a few). The few case studies of previous CBRN incidents have lead experts to identify key characteristics of terrorist groups that would potentially have an interest in CBRN weapons. Most of them agree that apocalyptic or religious extremist groups are the most likely to use CBRN weapons. However, although groups that present such characteristics might be the most dangerous ones regarding the subject matter, I think that the assumptions underlying these conclusions are misleading. To overcome these issues, this paper will attempt to follow the same analytic pattern, identifying shared characteristics of groups that have turned to CBRN terrorism through four case studies. It will then present the conclusions drawn by academics and experts in major research papers and discuss them, stressing the risk of misconceptions regarding CBRN weapons. Finally, this paper will argue that the type of a group is too reductive to determine effectively which group(s) are most likely to use CBRN weapons and is not as crucial as the combination of factors that might lead the group to this decision.

Four different case studies are usually discussed when experts want to determine the characteristics of potential users of CBRN weapons. Three of them are large-scale “successful” CBRN attacks, while the last one is a potential threat that seems to be a major concern for the US government and the international community as a whole. Chronologically, the first successful CBRN attack happened in 1984, when the Rajneeshee religious cult poisoned 751 people, spreading Salmonella typhimurium bacteria over ten salad bars. No fatality was reported. The aim of the attack was to influence a local vote in Oregon by limiting the voter turnout. Another deadly agent, Salmonella typhi, had been suggested to the leader of the group, Bhagwan Shree Rajneesh, but he reportedly refused, claiming that the attack was aiming at incapacitating people, not killing them. The second case occurred in 1990 in Sri Lanka. The Liberation Tigers of Tamil Eelam (LTTE), a separatist militant organisation active in the north of the country, assaulted a military facility using chlorine gas. At least 60 soldiers got sick due to gas exposure, although no fatality was reported. The operation was a success, despite that members of the LTTE got exposed to chlorine when the wind shifted. The third case, previously mentioned, was the 1995 release of sarin gas in the Tokyo subway by the religious cult Aum Shinrikyo. The attack killed 12 people and injured 200, while up to 5,000 stormed in hospitals believing they had been exposed. Finally, the last case study is Al Qaeda’s reported attempt to acquire and intention to use a CBRN weapon. Extensive evidence can be found to support this statement: the declaration of bin Laden in 1998 that acquiring CBRN weapons ‘is a religious duty’ (remaining very vague regarding its actual possession of such weapons), the 2003 fatwa (a religious decree) condoning the killing of 4 Million of Americans, described as a legitimate act of vengeance, as well as numerous documents found in Afghanistan attesting of active researches and experiments in CBRN weapons. A whole volume of Al Qaeda’s “Encyclopaedia of Jihad” even details the construction of Chemical and Biological weapons. Although it is not clear whether Al Qaeda remains at an early stage of development of CBRN weapons, there is no doubt regarding the organisation’s interest in such weapons.

Even though these case studies differ by many more aspects than they resemble each other, they share a few common points. In all four cases, a charismatic leader was involved: Prabakaran, leader of the LTTE, controlled the entire life of his followers up to their diet, bin Laden required that Al Qaeda’s members swore allegiance to him (bay’ah), while Bhagwan Shree Rajneesh and Shoko Asahara were the spiritual leaders of their cult. In the case of Asahara, he had a huge influence over his followers, predicting the end of the world and promising salvation to all members of Aum. Indeed, a charismatic leader is an important factor for a group that would turn to CBRN terrorism: the influence of the leader can be so important that his decisions are enough to suppress any moral constraint that a member would have, because he holds the truth and the justification of all the actions carried out by the group. Moreover, he is the only one bearing responsibility for them, the individual fading away in the group as a whole. An analogue argument regarding a divine justification of religious groups’ actions is also often put forward. In two cases, members of the group had a personal interest or obsession with CBRN weapons: Ma Anand Puja, the member of the Rajneeshees who suggested the use of Salmonella typhi, was suspected of being a ‘serial poisoner’, while Aum Shinrikyo had a very hierarchical organisation with scientists as head of chemical and biological departments, not to mention Asahara personal fascination with unconventional weapons. He even wrote a song about sarin, titled ‘Song of Sarin, the Magician’. Social alienation also played an important role in the Aum and Rajneeshee cults: after losing the 1990 elections, Aum decided that no one from outside of the group could be saved, drawing a clear line between “us” and “them”, while the Rajneeshees were living in a small community in Waso County, isolated from anyone else. The consequence of this alienation was that any exterior social constraint regarding violence would have no impact on the group’s decisions. Finally, religion was a factor in three of these cases, or at least a major characteristic of the groups involved.

But that is as far as this comparison goes. The use of CBRN weapons was a rational choice that addressed very different needs and objectives in each case. While it played a central role in Aum’s prophesised apocalypse (although the 1995 sarin attack was a desperate action triggered by a planned operation of the Japanese police to close in on the group’s facilities), the LTTE only resorted to chemical weapons that one time because of a shortage of conventional weapons and has never used chlorine again. While Al Qaeda might be willing to use CBRN weapons for their psychological and symbolic impact, which requires visibility, the Rajneeshees’ attack went unnoticed for over a year. According to John Parachini, Director of the Intelligence Policy Center at the RAND Corporation, the role of religion has been played up, even in the cases of Aum and Al Qaeda. Asahara had an egocentric personality and wanted to be the emperor of the post-Armageddon world, one of the few to actually survive the end of the world. Bin Laden’s divine justification of a holy war can be regarded as a personal vanguard against the United States and its allies. The Rajneeshee was a religious cult but had a secular objective (winning a local election). Therefore, it seems that a simple profile of a group willing to use CBRN weapons cannot be deducted from these case studies only.

The literature on the subject reveals two different trends: one that mostly expends on the case studies mentioned above as well as minor CBRN incidents, using a qualitative approach to establish a typology of groups most likely susceptible to resort to CBRN weapons, and a second one using a quantitative approach, exploiting the CBRN terrorism database of the Monterey Institute of International Studies. It is worth noticing that the findings of both the approaches differ at some point. Regarding the qualitative approach, the different typologies are very similar in their content. I present here Drs. Charles Ferguson and Wiliam Potter’s typology of terrorist groups according to their potential interest in nuclear terrorism, but it differs very little from Professor Robin Frost’s. Ferguson and Potter focus their study on four types of groups: ‘apocalyptic groups’, ‘politico-religious groups’, ‘nationalist/separatist groups’ and ‘single-issue terrorists’. According to them, apocalyptic groups pose the greatest threat when it comes to nuclear terrorism, because some of them might want to bring about the Apocalypse they foresee, in which case the means becomes the end itself. The key characteristics of such groups are ‘charismatic leaders, isolation and alienation from the larger society, sense of paranoia and grandiosity’. It is obvious that this category refers directly to Aum Shinrikyo, which is nonetheless a very specific religious cult that cannot be compared to any other existing terrorist group.

The second category they mention is ‘politico-religious groups’, cause and offspring of the 9/11 attacks. They call such groups ‘hybrids’ as an answer to those who claim that Al Qaeda’s objectives are not only religious, but also political (creation of a global caliphate, but also pushing the United States out of the Middle East). Ferguson and Potter contend that nuclear weapons might appeal to such groups, using the example of Al Qaeda that is willing to inflict mass casualties to the West. Whether the group would actually use a nuclear weapon if it managed to acquire one is not discussed by the authors, but that is a debatable point to which we will come back later.  Interestingly, Frost puts apocalyptic groups and politico-religious groups into one single category, ‘religious terrorism’, that encompasses altogether the Rajneeshee, Aum Shinrikyo and Al Qaeda. He insists on the threat posed by a divine justification of an act presented as a religious imperative.

The third category of Ferguson and Potter’s typology, nationalist/separatist groups, also appears in Frost’s typology. The authors all agree on the disincentives such groups might be confronted with when it comes to using nuclear weapons. These groups, like the Irish Republican Army or Chechen rebels to name a few, are depending on their base constituency’s support and therefore cannot risk to alienate them by undertaking actions that they would not approve of. It was the case for the Real IRA, an offshoot of the IRA responsible for the bombing of a shopping centre in Omagh, Northern Ireland, which lost the support of the population after this operation, leading to its dismantlement. These groups present themselves as “freedom fighters” in order to gain international support and claim to merely target military and governmental installations, although Frost mentions that their rhetoric does not deceive anyone: out of 1,800 victims of the IRA between 1969 and 1994, 600 were civilians. Using a nuclear weapon would be counterproductive according to their strategy, although Ferguson and Potter claim that they ‘might benefit from appearing to have the capability’, an argument that they oppose themselves, mentioning the radicalisation of the government’s stance every time Chechens have mentioned resorting to CBRN weapons. Finally, being geographically focused, they would risk a massive retaliation from the country they would attack, potentially leading to their annihilation.

The last category of Ferguson and Potter are single-issue terrorists (eco-terrorists, anti-nuclear activists, animal liberationists, anti-abortionists, etc…). According to them, these groups do not represent a threat insofar as they have very targeted goals that do not include mass casualties. In this category, Frost mentions an exception: ‘green anarchists’, terrorists who advocate a rebirth of the earth through the annihilation of the human race. This sub-category presents similarities with apocalyptic groups and might very well be willing to use a nuclear weapon to achieve its end, with very little moral constraint whatsoever. Frost also adds ‘social-revolutionary’ and ‘right-wing’ groups in his typology, but argues that nuclear weapons would probably not appeal to them, as they present similarities with nationalist/separatist groups.

Other qualitative studies have also addressed the typology of groups that would be interested in using biological weapons, which is considered to be the most likely scenario of a CBRN attack by most articles in the literature. According to Francisco Galamas, Islamic extremist groups are the most likely to use biological weapons, because they are set on killing non-believers in an indiscriminate manner. Biological weapons have the potential to kill thousands and could be effectively combined with suicide tactics to provoke mass casualties, such as using a contaminated terrorist to propagate a pathogen in a public area. This argument would however be refuted by Adam Dolnik, who underlines the differences between a suicide bomb attack and a suicide CBRN attack, the latter lacking any of the incentives of the former. According to Galamas’ typology, the second group that is most likely to use a biological weapon are religious cults. The author draws his argument from the examples of the Rajneeshee’s Salmonella poisoning and Aum’s numerous attempts to produce and use Botulinum toxin and anthrax between 1990 and 1993. It is worth noticing that religion remains the primary factor in biological weapons qualitative studies.

The main quantitative studies have been conducted by Kate Ivanova and Todd Sandler in 2006 and 2007, using data of hundreds of CBRN attacks indexed on the Monterey Institute’s CBRN terrorism database from 1988 to 2004. Their findings indicate that democracy, past CBRN incidents, corruption and transnationalism increase the risks of a CBRN attack. However, Ivanova and Sandler have also found that ‘religious fundamentalists and nationalists/separatists do not present (…) a CBRN concern’. According to them, non-religious groups are five times more likely to use CBRN weapons than religious groups. However, these results are not entirely at odds with qualitative studies, because Ivanova and Sandler found that religious groups that are also transnational – such as Al Qaeda – were the most likely to use CBRN weapons.  Nevertheless, it would seem that the factor “transnational” is of the uttermost importance and that religion alone does not support the use of a CBRN weapon.
All these studies attempt to profile groups that would be interested in using CBRN weapons. However, some of the assumptions they base their arguments on can be misleading. I will discuss three points that are often overlooked in the literature. First of all, I do not think like Frost that ‘the decision to “go nuclear” would necessarily involve the intention to do so’. For example, in my opinion, Al Qaeda would probably benefit more from pretending to have a CBRN weapon than using one. The group is not insensitive to its followers’ opinion, otherwise the organisation would not have felt the need to justify the killings of 9/11. However, claiming to “potentially” have a CBRN weapon is a cost free psychological weapon in itself. Therefore, whether Al Qaeda would actually use a CBRN weapon is debatable. Another misconception is that CBRN weapons are necessarily weapons of mass destruction, and that terrorists would automatically use them to kill a lot of people and carry out an attack more spectacular than 9/11. Given its psychological impact, a CBRN attack does not need to make mass casualties to reach what Ivanova and Sandler call the ‘media bar’ of 9/11. Moreover, to date, conventional attacks have proven far more lethal than CBRN attacks. Therefore, it appears that the “mass casualty” factor is not necessarily fundamental to explain the choice of a group to use a CBRN weapon.

This paper has attempted to show that the traditional approach consisting in determining the type of non-state actors most likely to use CBRN weapons through typologies and case studies might lead to false conclusions, when trying to fit all groups in one single model. CBRN weapons are very different from each other, and the motives explaining why one group would choose to develop and use one particular agent depends on its own objectives and characteristics. While these characteristics can be shared with other groups, they are not self-sufficient. Therefore, this paper argues that a correct approach to the issue would be to think of it as a threshold depending on a combination of all the characteristics mentioned above. Religion is not enough to resort to CBRN weapons, but if a religious group is also transnational, apocalyptic and lead by a charismatic figure, it becomes much more likely to use a CBRN weapon. This proposition would also explain why the Aum Shinrikyo case, symbol of CBRN terrorism, is unique and unlikely to be replicated: many positive factors have simultaneously converged to one very specific group.

Bioterrorism and the Pandemic Potential (Stratfor; March 7, 2013)

By Rebecca Keller
 
Periodic media reports of bird flu, a new SARS-like virus and a case of drug-resistant tuberculosis have kept the world informed, but they have also contributed to a distorted perception of the true threat such contagions pose. Perhaps the greatest value of the media coverage is the opportunity it provides to discuss the uncertainties and the best ways to prepare for biological threats, both natural and man-made.
 
It is important to remember that the risk of biological attack is very low and that, partly because viruses can mutate easily, the potential for natural outbreaks is unpredictable. The key is having the right tools in case of an outbreak, epidemic or pandemic, and these include a plan for containment, open channels of communication, scientific research and knowledge sharing. In most cases involving a potential pathogen, the news can appear far worse than the actual threat.
 
Infectious Disease Propagation
 
Since the beginning of February there have been occurrences of H5N1 (bird flu) in Cambodia, H1N1 (swine flu) in India and a new, or novel, coronavirus (a member of the same virus family as SARS) in the United Kingdom. In the past week, a man from Nepal traveled through several countries and eventually ended up in the United States, where it was discovered he had a drug-resistant form of tuberculosis, and the Centers for Disease Control and Prevention released a report stating that antibiotic-resistant infections in hospitals are on the rise. In addition, the United States is experiencing a worse-than-normal flu season, bringing more attention to the influenza virus and other infectious diseases.
 
The potential for a disease to spread is measured by its effective reproduction number, or R-value, a numerical score that indicates whether a disease will propagate or die out. When the disease first occurs and no preventive measures are in place, the reproductive potential of the disease is referred to as R0, the basic reproduction rate. The numerical value is the number of cases a single case can cause on average during its infectious period. An R0 above 1 means the disease will likely spread (many influenza viruses have an R0 between 2 and 3, while measles had an R0 value of between 12 and 18), while an R-value of less than 1 indicates a disease will likely die out. Factors contributing to the spread of the disease include the length of time people are contagious, how mobile they are when they are contagious, how the disease spreads (through the air or bodily fluids) and how susceptible the population is. The initial R0, which assumes no inherent immunity, can be decreased through control measures that bring the value either near or below 1, stopping the further spread of the disease.
 
Both the coronavirus family and the influenza virus are RNA viruses, meaning they replicate using only RNA (which can be thought of as a single-stranded version of DNA, the more commonly known double helix containing genetic makeup). The rapid RNA replication used by many viruses is very susceptible to mutations, which are simply errors in the replication process. Some mutations can alter the behavior of a virus, including the severity of infection and how the virus is transmitted. The combination of two different strains of a virus, through a process known as antigenic shift, can result in what is essentially a new virus. Influenza, because it infects multiple species, is the hallmark example of this kind of evolution.
 
Mutations can make the virus unfamiliar to the body's immune system. The lack of established immunity within a population enables a disease to spread more rapidly because the population is less equipped to battle the disease. The trajectory of a mutated virus (or any other infectious disease) can reach three basic levels of magnitude. An outbreak is a small, localized occurrence of a pathogen. An epidemic indicates a more widespread infection that is still regional, while a pandemic indicates that the disease has spread to a global level.
 
Virologists are able to track mutations by deciphering the genetic sequence of new infections. It is this technology that helped scientists to determine last year that a smattering of respiratory infections discovered in the Middle East was actually a novel coronavirus. And it is possible that through a series of mutations a virus like H5N1 could change in such a way to become easily transmitted between humans.
 
Lessons Learned
 
There have been several influenza pandemics throughout history. The 1918 Spanish Flu pandemic is often cited as a worst-case scenario, since it infected between 20 and 40 percent of the world's population, killing roughly 2 percent of those infected. In more recent history, smaller incidents, including an epidemic of the SARS virus in 2003 and what was technically defined as a pandemic of the swine flu (H1N1) in 2009, caused fear of another pandemic like the 1918 occurrence. The spread of these two diseases was contained before reaching catastrophic levels, although the economic impact from fear of the diseases reached beyond the infected areas.
 
Previous pandemics have underscored the importance of preparation, which is essential to effective disease management. The World Health Organization lays out a set of guidelines for pandemic prevention and containment. The general principles of preparedness include stockpiling vaccines, which is done by both the United States and the European Union (although the possibility exists that the vaccines may not be effective against a new virus). In the event of an outbreak, the guidelines call for developed nations to share vaccines with developing nations. Containment strategies beyond vaccines include quarantine of exposed individuals, limited travel and additional screenings at places where the virus could easily spread, such as airports. Further measures include the closing of businesses, schools and borders.
 
Individual measures can also be taken to guard against infection. These involve general hygienic measures -- avoiding mass gatherings, thoroughly washing hands and even wearing masks in specific, high-risk situations. However, airborne viruses such as influenza are still the most difficult to contain because of the method of transmission. Diseases like noroviruses, HIV or cholera are more serious but have to be transmitted by blood, other bodily fluids or fecal matter. The threat of a rapid pandemic is thereby slowed because it is easier to identify potential contaminates and either avoid or sterilize them.
 
Research is another important aspect of overall preparedness. Knowledge gained from studying the viruses and the ready availability of information can be instrumental in tracking diseases. For example, the genomic sequence of the novel coronavirus was made available, helping scientists and doctors in different countries to readily identify the infection in limited cases and implement quarantine procedures as necessary. There have been only 13 documented cases of the novel coronavirus, so much is unknown regarding the disease. Recent cases in the United Kingdom indicate possible human-to-human transmission. Further sharing of information relating to the novel coronavirus can aid in both treatment and containment.
 
Ongoing research into viruses can also help make future vaccines more efficient against possible mutations, though this type of research is not without controversy. A case in point is research on the H5N1 virus.
 
H5N1 first appeared in humans in 1997. Of the more than 600 cases that have appeared since then, more than half have resulted in death. However, the virus is not easily transmitted because it must cross from bird to human. Human-to-human transmission of H5N1 is very rare, with only a few suspected incidents in the known history of the disease. While there is an H5N1 vaccine, it is possible that a new variation of the vaccine would be needed were the virus to mutate into a form that was transmittable between humans. Vaccines can take months or even years to develop, but preliminary research on the virus, before an outbreak, can help speed up development.
 
In December 2011, two separate research labs, one in the United States and one in the Netherlands, sought to publish their research on the H5N1 virus. Over the course of their research, these labs had created mutations in the virus that allowed for airborne transmission between ferrets. These mutations also caused other changes, including a decrease in the virus's lethality and robustness (the ability to survive outside the carrier). Publication of the research was delayed due to concerns that the results could increase the risk of accidental release of the virus by encouraging further research, or that the information could be used by terrorist organizations to conduct a biological attack. Eventually, publication of papers by both labs was allowed.
 
However, the scientific community imposed a voluntary moratorium in order to allow the community and regulatory bodies to determine the best practices moving forward. This voluntary ban was lifted for much of the world on Jan. 24, 2013. On Feb. 21, the National Institutes of Health in the United States issued proposed guidelines for federally funded labs working with H5N1. Once standards are set, decisions will likely be made on a case-by-case basis to allow research to continue.
 
Fear of a pandemic resulting from research on H5N1 continues even after the moratorium was lifted. Opponents of the research cite the possibility that the virus will be accidentally released or intentionally used as a bioweapon, since information in scientific publications would be considered readily available.
 
The Risk-Reward Equation
 
The risk of an accidental release of H5N1 is similar to that of other infectious pathogens currently being studied. Proper safety standards are key, of course, and experts in the field have had a year to determine the best way to proceed, balancing safety and research benefits. Previous work with the virus was conducted at biosafety level three out of four, which requires researchers wearing respirators and disposable gowns to work in pairs in a negative pressure environment. While many of these labs are part of universities, access is controlled either through keyed entry or even palm scanners. There are roughly 40 labs that submitted to the voluntary ban. Those wishing to resume work after the ban was lifted must comply with guidelines requiring strict national oversight and close communication and collaboration with national authorities. The risk of release either through accident or theft cannot be completely eliminated, but given the established parameters the risk is minimal.
 
The use of the pathogen as a biological weapon requires an assessment of whether a non-state actor would have the capabilities to isolate the virulent strain, then weaponize and distribute it. Stratfor has long held the position that while terrorist organizations may have rudimentary capabilities regarding biological weapons, the likelihood of a successful attack is very low.
 
Given that the laboratory version of H5N1 -- or any influenza virus, for that matter -- is a contagious pathogen, there would be two possible modes that a non-state actor would have to instigate an attack. The virus could be refined and then aerosolized and released into a populated area, or an individual could be infected with the virus and sent to freely circulate within a population.
 
There are severe constraints that make success using either of these methods unlikely. The technology needed to refine and aerosolize a pathogen for a biological attack is beyond the capability of most non-state actors. Even if they were able to develop a weapon, other factors such as wind patterns and humidity can render an attack ineffective. Using a human carrier is a less expensive method, but it requires that the biological agent be a contagion. Additionally, in order to infect the large number of people necessary to start an outbreak, the infected carrier must be mobile while contagious, something that is doubtful with a serious disease like small pox. The carrier also cannot be visibly ill because that would limit the necessary human contact.
 
As far as continued research is concerned, there is a risk-reward equation to consider. The threat of a terrorist attack using biological weapons is very low. And while it is impossible to predict viral outbreaks, it is important to be able to recognize a new strain of virus that could result in an epidemic or even a pandemic, enabling countries to respond more effectively. All of this hinges on the level of preparedness of developed nations and their ability to rapidly exchange information, conduct research and promote individual awareness of the threat.
