Assessment of the Biological Weapons Threat to the United States,
"White Paper" prepared for the Conference on Emerging
Threats Assessment. Biological Terrorism, at the Institute for
Security Technology Studies, Dartmouth College, July 7-9, 2000.
There are five essential requirements that must be mastered in order
to produce biological agents:
 | One must obtain the appropriate strain of the disease pathogen. |
 | One must know how to handle them correctly. |
 | One must know how to grow them in a way that will produce the
appropriate characteristics. |
 | One must know how to store them, and to scale-up production
properly. |
 | One must know how to disperse them properly. |
Four of the five requirements are in the portion frequently dismissed
as "easy." Some experts do stress that the last step,
aerosolization to the appropriate particle size for efficient inhalation
infection, does present difficulties, while suggesting that the first
four steps are simple. That is clearly not correct. Instead of dealing
with this subject by abstract pronouncements, as is customary and the
more so the less initiated the commentator, it would be more useful to
provide real examples from the experiences of several national
biological weapons programs.
First, there is the problem of obtaining a strain of the organism in
question that is useful for biological weapons purposes. Most natural
forms of biological agents are not highly infectious, and it is not that
easy to obtain the strains that are highly infectious. For example, in
the course of the offensive phase of the US BW program, roughly 675
strains of Clostridium botulinum were gathered. More extensive
laboratory research was carried out using about a dozen of these
strains, and finally one strain that produced satisfactory titres
of toxin regularly under production conditions was selected for
weaponization purposes. Similarly for anthrax, the number of available
strains is high and weaponization was carried out on only a few of
these.
Secondly, even very practiced experts can run into significant
problems. Dr. Jerzy Mierzejewski, the retired director of the Polish
biological defense laboratories at Pulawy who spent his entire
professional career working with Clostridium botulinum, plaintively
expressed his persistent difficulties on working with the organism to
participants at two NATO Advanced Research Workshops. One culture cycle
would produce toxin that was lethal and a few months later the next
would not, and so on over the years. Even variations in the growth
parameters for non-pathogenic simulants could seriously degrade their
intended performance. The British BW testing program used two common
simulants, Bacillus globulii, and an E.Coli strain. It was discovered
that even minor variations in their culturing parameters could seriously
degrade their performance in aerosol dispersion tests.
As for more complicated integration of the entire process, another
example is of value. Dr. William Patrick described the outcome of a
study carried out recently at USAMRIID. A post-doctoral fellow was given
the task of outlining how he would produce a mass casualty event using a
designated organism that had been developed as a weapon in the pre-1969
US BW program – Tularemia. He was given one year in which to complete
his assignment. When the year was up and he presented his project
design, it was found that it included three errors that would have
prevented the effort from being successful had it be carried out. Quite
unfortunately, Patrick has himself been responsible for publicly
describing critical technical details which there is every reason to
assume would not be known to uninitiated non-state or terrorist
groups interested in producing or using biological agents.
At a meeting on "Bioterrorism in the United States" held on
June 29-30 in Washington, DC, Jerome Hauer, former Director of the
Office of Emergency Management for the City of New York, stressed that:
 | "Most of the agents are not readily available, |
 | "Most of the agents are not easy to make, and |
 | "Most of the agents are not easy to disperse." |
As regards aerosol dispersal in particular, Tucker and Sands write:
The capability to disperse microbes and toxins over a wide area as
an inhalable aerosol – the form best suited for inflicting mass
casualties – requires a delivery system whose development would
outstrip the technical capabilities of all but the most sophisticated
terrorists. Not only is the dissemination process for biological
agents inherently complex, requiring specialized equipment and
expertise, but effective dispersal is easily disrupted by
environmental and meteorological conditions.
At the end of World War II, the US BW program at Fort Detrick
comprised some 250 buildings and employed approximately 3,400 people.
The number of person-years that were required to weaponize as
"simple" an agent as botulinum toxin, together with access to
highly qualified personnel, excellent facilities, and extensive testing
ranges is quite significant.
Dr. Ken Alibek has given the figure of a combined total of 60,000
people (at all levels of technical expertise, from service personnel to
scientists) in all of the multiple segments of the former USSR’s BW
program: Ministry of Defense, Biopreparat, Ministry of Agriculture,
Ministry of Health and so on. Senior scientists may have accounted for
less than 5 percent of this total, and in seminars, Dr. Alibek has
stated that although there were many experts that knew the precise
details of an individual stage of the research or production process,
there were perhaps only 100 individuals who knew how to take a
particular organism that the USSR had weaponized through all its stages
from beginning to end in the production process.
The Iraqi BW program began in 1974 or earlier, and between 1979 and
1985 a large number of their BW research staff were sent overseas for
advanced study and degrees because it was apparent that work was not
progressing and that they were not sufficiently trained and qualified.
When the 200-300 BW researchers went back to work, they were supported
by a separate contingent of over 1,000 technical people in the Iraqi
chemical weapons program who carried out the BW testing program. The
Iraqi BW program consumed upwards of $100 million.
One only has to compare the above with some of the descriptions of
the supposed ease in producing biological agents that have been common
in recent years. One author wrote that "manufacturing a lethal
bacterial disease agent requires little more than chicken soup, a flat
whiskey bottle, and an available source of seed culture." Another
wrote that producing biological weapons was "...about as
complicated as manufacturing beer and less dangerous than refining
heroin." In seminar presentations a few years ago, former CIA
Director James Woolsey would claim that "a B-plus high school
chemistry student" could produce biological agents, and at a
January 2000 meeting described producing biological agents as being
"about as difficult as producing beer." In her book, The
Ultimate Terrorist, Jessica Stern quotes:
Kathleen Bailey [who], after interviewing professors, graduate
students, and pharmaceutical manufacturers, concluded that several
biologists with only $10,000 worth of equipment could produce a
significant quantity of biological agent.
One can also compare these rather common and gross exaggerations with
the real-world experience of the Aum Shinrikyo group:
 | They had appropriate equipment (even more than was necessary). |
 | They used commercial front companies to buy the equipment. |
 | They may have spent in the range of $10 million in their effort to
produce biological agents. |
 | Several of the individuals involved had post-graduate degrees. |
 | They had gathered a research library. |
 | They had sufficient time – four years – for their attempts. |
 | They had attempted to purchase expertise in Russia and to obtain
or purchase disease strains in Japan. |
However, they failed in their efforts to produce either of two
biological agents. |
