Why did the DOE’s Lawrence Livermore National Lab produce a 2015 study suggesting that anthrax was NOT used as a bioweapon in Rhodesia’s civil war?

By Meryl Nass, M.D.  Dr. Nass is  a board-certified internist and a biological warfare epidemiologist and expert in anthrax. Nass publishes Anthrax Vaccine.

Rhodesia is no more, having been renamed Zimbabwe after it became a majority-ruled black nation in 1980. Rhodesia was a British territory before 1965, when the 5% white minority seized control to preclude Britain granting majority rule.  A civil war ensued, with the two sides divided by race.  By the war’s end in 1980, the black “guerrilla” “terrorist” “communist” side had been attacked with chemical and biological weapons including organophosphate “nerve gas,” rat poison, cholera, anthrax and arguably other chem-bio agents.

I was first to publicly identify this anthrax epidemic, which killed at least 182 people and affected 10,000, to be an act of biological warfare, in 1992.  Subsequently much literature (scientific, historical and memoir, originating from Zimbabwe, South Africa, the UK and US) has amplified the evidence base and added details, though much remains hidden. Of interest, this confirmatory literature includes a report from the US Naval War College and US Air War College, and a book and related episode of BBC TV’s Panorama.  The history of anthrax biowarfare in Rhodesia seemed incontrovertible.

US DOE’s Lawrence Livermore National Laboratory takes aim at this history, misses widely

I was forwarded a report produced in 2015 by a scientist at Lawrence Livermore National Laboratory (LLNL), disputing that the Rhodesian anthrax epidemic was due to biological warfare. The study was published by LLNL, rather than in a peer-reviewed journal, yet it required considerable resources to produce. The report ran to 43 pages and 56 footnotes.

In order to claim the epidemic occurred naturally, the report’s author, Stephan P Velsko, employed a method he termed “opinion calculus,” by which he transmuted the actual facts of the epidemic into opinions and (often incorrect) assertions. He then assigned weights to the opinions and assertions (the weights being his opinions) and used a mathematical construct, Dempster-Shafer theory, to impart a scientific veneer to the gobbledygook calculations.

Unable to marshall any evidence to support his conclusion that biological warfare did not occur, Velsko jettisoned all the existing evidence to instead favor the absence of evidence, claiming,  “Many items of evidence that have been proffered over the years are shown to be nearly irrelevant to the final conclusion, while the absence of certain expected types of evidence plays a critical role in the assessment.” 

Here are three examples (from many more I could cite) of Velsko/LLNL’s arguments:

1.  Although anthrax cases were required to be reported in Rhodesia, Velsko disputes the meaning of the huge size of the epidemic, suggesting it was inflated by poor quality reporting.  While reporting rates for any rare disease always increase as doctors become more familiar with it, Velsko never mentions the fact that the Rhodesian event remains, by far, the largest anthrax epidemic in world history.

2.  Velsko disputes that the epidemic jumped from district to district in a geographic and temporal pattern unknown to other anthrax epidemics, twisting the history. He claims instead that the epidemic was localized to one epicenter, with nearby peripheral cases caused by transport of meat.  In order to make this claim, he omits the considerable evidence of when and where cases occurred.

However, I previously recorded the dates and locations of cases using Zimbabwe’s public health records and other sources.  Below is a new photo of the map I annotated in 1992 with multicolored stars for reported anthrax case locations, and numbers of cases, where known.  Some of the stars have gone missing, but it should be obvious that cases were identified widely within Zimbabwe’s borders (marked in yellow).  Visible, but more difficult to see, are the case numbers which, despite Velsko’s claims, were considerable from east of Harare to northwest of Bulawayo. Additionally, the star colors indicate the temporal movement of the epidemic to new areas, a feature unique to this epidemic but disputed by Velsko.

3.  Velsko challenges the validity of an ex-Rhodesian intelligence officer’s report, simply because anthrax spores were referred to as “spoor.” Velsko writes, “the mistaken use of the term “spoor” instead of “spore” leads one to suspect that the author of the letter did not have direct experience with B. anthracis, and was at best quoting others.”  However, “spoor” is the correct term in the Afrikaans language (spoken by the white Afrikaaners of South Africa) for spore, and in common use to denote anthrax.  While I don’t expect Velsko to know Afrikaans, his argument encapsulates the confluence of ignorance and flawed reasoning that characterize the entire report.

Although I could go on about the misleading claims and suppositions in this “study,” the real question of interest is why did the DOE’s Lawrence Livermore National Laboratory, a storied federal center for studies of nuclear, chemical and biological weapons, including anthrax, choose to dispute that anthrax biowarfare took place in Rhodesia?  Why now, 37 years after the event, and 23 years after my paper was first published?

Velsko is a math and microbial forensic guy who has written on techniques for establishing the forensic origin of disease.  He has also written on the anthrax letters, and on scientific validation in microbial forensics.  I don’t think he is a fool.  Is he a knave?

Did Velsko/LLNL simply choose to experiment with a new technique, and picked the Rhodesian anthrax epidemic to study, randomly?  If so, why choose a technique that heaps guesswork on guesswork, while ignoring the available data?  That ain’t science and I’d wager Velsko knows it.

Why was this report written?

The report’s conclusion, that Rhodesia’s anthrax epidemic was probably a natural occurrence, may be the first volley of an effort intended to alter history.  Why would a US government lab want to do this, unless the US government had some involvement in that history?

Here’s another scary possibility:  the US government finds itself stymied by the existence of a method that can distinguish whether an epidemic is deliberately caused, or a natural occurrence.  A major reason to use a biological weapon is that the resulting epidemic will be assumed to be natural, and go undetected as an offensive act.  A further reason to use a biological weapon is that it is almost impossible to detect who did it.  [Consider the anthrax letters attack and that we still lack proof of their perpetrator.] Velsko and LLNL know this:  this is their field, after all.

Might Velsko and his employer LLNL/DOE/USG be trying to weaken the scientific underpinning of biowarfare epidemic analysis, an analysis that could be used outside US Government-approved channels, to make the investigative techniques appear much softer and less reliable than they really are? Might this be an effort to prevent their future use to detect a biological weapon attack?

    The neo-conservative war criminal syndicate is extending its’ reach into science and history to bury inconvenient truths. Thanks to Dr. Nass and others like him the truth has a voice. It is tragic that within the US public administration people are paid to fabricate such elaborate deceptions in relation to war crimes, climate change, genetic engineering and ongoing events in places like Syria and Ukraine.
    Thank-you to Washingtons Blog, to Dr. Nass and your other writers. You excel in exposing the devious machinations of corrupted government institutions and keeping the world informed with the truth.

    Thank you for exposing some of our real history. The national security state was created to hide crimes of the past, present and future. The reality of it’s actions are so abominable, it must be hidden by lies and deceit to the public. The public has become complicit, as atrocities that are immediately recognizable and verifiable, are practically adored by almost all, and it’s not only the United States, The global corporate empire has superseded the common good in what is now becoming a global security state and apparatus to lock down the masses to perform as Kissinger has called, useless resource eaters.
