Talk:Poisoning of Sergei Skripal

Skripal and Steele dossier
I do not think Skripal' played a big role in Steele dossier. He is not a 'trusted compatriot', obviously, and even less an insider like 'a former intelligence officer still active in Kremlin', or 'a senior Russian Foreign Ministry figure', etc (in Steele dossier open version, info is attributed to trusted compatriots who are friends of insiders, or some auxiliary figures like hotel workers with allegedly first-hand knowledge
 * Source E provided an introduction for a company ethnic Russian operative to Source F, a female staffer at the hotel when TRUMP had stayed there, who also confirmed the story.--here I am not getting the language, what's the  'company'  that operative is working for?
 * "Company" in the Steele dossier refers to Steele's company "Orbis Business Intelligence". -- Petri Krohn (talk) 23:40, 8 March 2018 (UTC)

Not being an insider or trusted friend, his role is at most minimal. On top of it, the report is pretty ridiculous and I think nobody took it too seriously. So what's the point going after Skripal, for his (alleged) role in the report? This would create much more damaging to Russia situation than Steele report itself--Resup (talk) 23:23, 8 March 2018 (UTC)
 * What would be the point of accusing Trump of murdering Skripal? Gee! Maybe Trump and Putin murdered him together!
 * Quote: ''The dossier has sparked a formal investigation in the US into Russian collusion in the US presidential election, to the fury of both presidents Trump and Putin.
 * ''If the Kremlin believed that Col Skripal might have helped with the compilation of the dossier, it could explain the motive for the assassination attempt in Salisbury town centre.

'Gift'?

 * Poisoned Russian spy Sergei Skripal’s daughter Yulia could have unwittingly released nerve agent after opening gift ‘from friends’ - The Sun, March 8, 2018
 * A theory not totally without merits, but unlikely. Bringing gifts is traditional; tainting a gift does not require sending operatives; it lowers threshold and may be attempted as personal revenge (say, by somebody directly affected by his actions, as it is said that he passed list of Russian agents to British services). But unlikely, everybody is aware of such possibility, even more so a former intelligence officer, and his daughter is enough of an adult and was with him long enough to know, too. I believe the occasion was anniversary of his son death, who had sudden liver failure, and poisoning suspected. It is unlikely that they will celebrate the event by drinking or eating something of uncertain origin, that would be odd. A gift is most likely opened at home well before the collapse, not taken to a restaurant (where it is said that traces found, and which is a likely place for poisoning to occur). Also, that 'gift' will be found and quite likely traced (assuming no false flagging). If it is traced to Russia, it can be brought to a Russian court, and cooperation is not out of the question. --Resup (talk) 08:28, 11 March 2018 (UTC)


 * Let's say there were two gifts, one left at the house and one taken to the restaurant; and Rozzer got poisoned when he inspected the remaining gift, or at least the packaging.
 * I'm guessing the gift was opened on the park bench and not before. I'm also guessing the poison wasn't that common as there would have been some official statement - rather that wild-arsed self-publicising guesses by HBG and equally self-serving vacuum filling rambling by Kaszeta. --Charles Wood (talk) 08:43, 11 March 2018 (UTC)

Flowers?

 * Was Russian spy poisoned by flowers? Chemical experts examine bouquet left by the double agent at his wife's grave -Daily Mail, March 10, 2018
 * Russian spy poisoning probe 'focusing on flowers he took to wife's grave' amid claims nerve agent found at restaurant -The Mirror, March 11, 2018
 * That seems unusual, fresh flowers coming from a 'friend'. 'Women's day' (March 8) approaching, could not resist?  But it is said that the placed the flowers on the grave some time (few hours) before they collapsed. Not impossible, but not very convincing either, unless confirmed by tests. Tabloids do not say who the 'friend' was, or from which side of the iron curtain. --Resup (talk) 15:47, 11 March 2018 (UTC)

Litvinenko again
One thing that is common to the Skripal and Litvinenko cases is that traces of poison were found in multiple places, all of which could not be explained by a single act of poisoning. Litvinenko met Mario Scaramella in a sushi restaurant in Piccadilly before he met Andrey Lugovoy and Dmitry Kovtun at the the Millennium Hotel. Both places had traces of Polonium 210.

Finding traces in multiple places unconnected to the assassination itself may be a sign that the traces were left intentionally as fake evidence. -- Petri Krohn (talk) 19:49, 11 March 2018 (UTC)


 * Litvinenko case may be different, or whatever, and I do not feel like going into it (not having anything to contribute too). Yet I note the official inquiry position: there were two poisoning incidents with Litvinenko, the first is much weaker, and estimated by hair growth to be some weeks earlier. While on October 16, 2006 he had a business meeting with Tim Reiley and the prime official suspects attending (6.87--6.101). They minus Reiley went to Itsu after that. Office where they met was found to be contaminated, and the officiial report attributes Itsu contamination to the same source (ie apparently 16 October, not Scaramella meeting of 1 November. Report also claims that a different table was contaminated (table they sat was provided by Scaramella) --Resup (talk) 21:22, 11 March 2018 (UTC)

Walter Litvinenko

 * Отец бывшего офицера ФСБ Литвиненко, обвинявший в смерти сына Россию, сожалеет о сказанном ('The father of a former FSB officer, Litvinenko, who blamed Russia for the death of his son, regrets what was said')-TV 1 (Russia), February 2, 2012
 * Lives in poverty, regrets his words, asks Russia for forgiveness and help returning to Russia
 * 'Something not right in Salisbury', ПУСТЬ ГОВОРЯТ talk show, TV 1 (Russia), March 20, 2018
 * Blames Goldfarb. Prior to that, claims poisoning happened many times, including the hospital (does not specify by whom, at that point).
 * Lugovoi in studio, makes comments on non-transparency prior to public investigation (~35:00). Walter Litvinenko (father) and Maxim (brother) arrive to the studio ('from Italy'). Walter  gives Lugovoi a touch on the shoulder, 1/2 embrace; he separates brother from Lugovoi; camera goes off to the presenter who draws our attention to that episode expressing surprise how they met the killer and poisoner. Father smiles, brother stays neutral/Mona Lisa'ish. Father goes ahead to tell that he spent the last 3 days of Alexnder life near him at the hospital. Polonium 210 claim made  '1/2 hour after his death', people with respirators/protective suits arrived. A meeting with many people was assembled. Walter Litvinenko tells us that Goldfarb elbowed him for starting to talk too early (blaming Russia for polonium attack, in a passionate manner). Walter then encountered young Goldfarb wife, weeping on a hospital bed. Walter claims that she said 'Walter, Alex (Goldfarb) killed Alexander (Litvinenko)'
 * A journalist sitting on the same coach as the Litvinenkos and Lugovoi reinforces the message, telling us that nobody in the West, BBC, etc, will reach out to have this sensational recording
 * The program is a regular commercial talk show on a state TV channel.

For the record. This is different matter from Skripal, they do not have to follow the same pattern. I am not really interested in revisiting Litvinenko case (and do not see how, too), or in expressing any opinion, either way. Technical investigation records are not open, public inquiry presumably had access, while we do not. Human stories are humans' stories, and can change for whatever reason or be inaccurate. I note that Russian television made claims blaming Berezovsky or his people earlier. Berezovsky successfully sued for libel in British court in 2010 --Resup (talk) 09:26, 21 March 2018 (UTC)

 * Yes, that's for sure, but according to presentation, (some) synthesis details were already in Mirzayanov book of 2008--Resup (talk)

Other investigators
Several names of scientists (or whistle-blowers) have been mentioned on our pages already, scattered somewhere. More names:
 * RIA Novosti interview with Professor Leonid Rink, March (21?), 2018
 * Did you have anything to do with creating what the British authorities call the "Novichok"?
 * Yes. This was the basis of my doctoral dissertation. At that time I worked in Shikhany, in the branch of GosNIIOKhT (State Research Institute of Organic Chemistry and Technology, during Soviet times was engaged in the development of chemical weapons), was a leading researcher and a head of the laboratory. Mirzayanov was simply a chromatographer (a chemist who deals with the separation and analysis of various mixtures of substances.) - Ed.). Analytic tasks in this field were not even connected with him. But he headed the department of countering foreign technical intelligence, defended our developments, so he had all the permissions. He did not take part in discussing the systems that were being created, he had no relation to the development of the system. Nevertheless, since among themselves the scientists are discussing everything, he was aware.
 * Kivelidi murder; Chechens. It was Rink who sold the ampoule with the poisonous substance to the mediator who gave it to the murderer. The poison was applied to the telephone in the office of Kivelidi, and his secretary also died. Igor Rink was given a conditional year (he also sold the substance to certain Chechens).1,2.
 * Vladimir Uglev (The Bell Eng., Rus., March 20, 2018), see also this section

Военные мафии Кремля (Military Mafias of Kremlin, Georgy Vachnadze, pp 119-120, Moscow 'Mir' and Marburg Blau Herner (1994)

Kuntsevich was accused of a deliberate lie by one of the real, but robbed by the rogue authorities of the authors of this binary chemical weapons, Vladimir Uglev. The widely publicized "Mirzayanov's case" was a continuation of the "Interview with a Loop on the Neck" story in the weekly Novoye Vremya (No. 6, 1993; we referenced below a translation, pp. 18-19). According to Uglev, Lenin's award to A. Kuntsevich, V. Petrunin (director of the head military chemical research center of the State Research Institute of Organic Chemistry and Technology) and S. Golubkov (first deputy minister of the chemical industry of the USSR) could be issued only after the production of a pilot binary industrial batch weapons, "components of which are now stored on a secret base in the Bryansk region."

Uglev belongs to the dubious honor of authorship of three out of five "combat options" of binary weapons, code-named "Novichok". Nothing of the kind has ever been done in the world after the most powerful poisonous gas, synthesized by the Swedish scientist in 1956(inaccurate attribution?), the VX gas. The discovery of Uglev and his colleagues is 5 to 8 times more deadly than VX, not to mention other phosphoric gases - Sarin and Soman.

"The substance synthesized by me," says Uglev, "can be relatively easily" disguised "as a product of peaceful chemistry in the event of an international inspection. Uglev confirmed Mirzayanov's statement in the press that in the list of chemicals and dual-use technologies published in September 1992, under Yeltsin's signature, almost all components of both the new binary and the former VX gas are missing, ...

Federation of American scientists publication, Ch.2, Russia, p.133, date not supplied

But in the fall of 1992, the MBR detained Vil Mirzayanov on the charge of disclosing state secrets. Mirzayanov had publicly written that Russia was working on a nerve gas weapon, which questioned Yeltsin’s statement in January 1992 that Russia would comply with the US-Soviet agreement on nonproliferation of chemical weapons. Vladimir Uglev, who was one of the chief chemical weapons designers, corroborated Mirzayanov’s allegations though no charges were filed against Uglev for revealing state secrets because he had deputy’s immunity as an elected official.

Kholstov
Victor Kholstov, chemical defense chief, talking after a question of lower-level UK representative woman (Ambassador not attending):

No formulas in Mirzayanov claims in 1990's, or in his book first published in Russian in early 2000. However, Czech(oslovakia) professor Matoushek (Jiri Matoushek from Brno, Czech republic?) around 1994 published (toxicology) details of several chemicals (for the purpose of defense against those). Another professor from Czech(oslovakia) whose name is Ivan Masek (this?) published toxicology and spectroscopy data in 1994 of 'several dozen' chemicals (also for defense purposed). Kholstov flashed several pages presumably with formulas and related information.

Studies, according to Kholostov, were conducted by Edgewood Arsenal (USA).

Information on new substances was received at OPCW; however chemical convention was already signed, in the processs of implementation, and amending documents will slow this down.

Presenters earlier stated that in 1996/1997 Russia destroyed its chemical weapons under international control

When Mirzayanov book (the US one, on Amazon) appeared and was about to appear, it was sent to OPCW, and OPCW technical council/secretariat/commission seriously studies it. Their conclusion is that (it may need further study in case of concern but there is no definite data confirming its properties at this stage).

Kholstov alleges that publication of Mirzayanov was (1) for financial reasons (2) possibly coordinated with Edgewood Arsenal.

 * ''The Iranian researchers synthesised five ‘Novichok’ agents, along with four deuterated analogues. They were all O-alkyl N-[bis(dimethylamino)methylidene]-P-methylphosphonamidate compounds (i.e. molecules with the typical nerve agent phosphorus group coupled to N,N,N’N’-tetramethylguanidine). The O-alkyl group was varied, with the methoxy, ethoxy, isopropoxy, phenoxy, and 2,6-dimethylphenoxy derivatives being prepared.

Did the Novichok program exist?
A comment by yoffa on Moon of Alabama:


 * ''I think the underlying assumption of your post - that a Novichok programme existed - is open to serious doubt.


 * ''The only source for the story of a Soviet/Russian programme to develop a new class of military nerve agents codenamed Novichoks is a defector in the 1990s named Vil Mirzayanov. He claimed that one of these compounds was 5 to 8 times more toxic than VX and that production of these compounds had continued after the Chemical Weapons Convention came into effect. He explained the many publications in the open literature by Soviet chemists on compounds with similar structures as a deception to provide cover for secret research on other more toxic compounds, and gave structures for these compounds.


 * ''A review of chemical warfare agents in 2016 (http://pubs.rsc.org/en/content/chapter/bk9781849739696-00001/978-1-84973-969-6) by Robin Black, who had just retired as head of the detection lab at Porton Down, states that there is no independent confirmation of Mirzayanov's claims about the chemical properties of Novichok compounds.


 * ''The report of the OPCW's Scientific Advisory Board's meeting in April 2013 made a similar statement, and did not recommend adding these compounds or their precursors to the list of scheduled chemicals banned or restricted under the CWC. The members of the scientific advisory board included people who, like Black, were heads of western chemical defence labs. These labs would almost surely have undertaken experimental tests of Mirzayanov's claims about the toxicity of these compounds. So if members of the scientific advisory board who were in a position to know the results of these experiments did not recommend adding these compounds to the list of scheduled chemicals, we can reasonably infer that they were not found to be military grade nerve agents.


 * ''The British government is now demanding that Russia make a full disclosure of its Novichok programme by Tuesday evening. A Russian denial that such a programme existed will be taken as proof of guilt.

-- Petri Krohn (talk) 03:05, 13 March 2018 (UTC)

'Novichok' is a word, not a weapon. Anything not seen before out of a broad class of chemicals, pesticide or nerve agent, may be called 'Novichok' and used for propaganda. It needs to be (1) specific chemical (2) detailed signature of the recovered sample. There could be a program called 'Novichok' back from Soviet days, or maybe there was no such thing, in any case this is classified. They are not going to declassify it on the basis of a magic word pronounced, this is not serious. Give them sample details, and not through May-media. Otherwise this is is really justification for whatever measures they have already prepared. --Resup (talk) 09:20, 13 March 2018 (UTC)
 * Lavrov: Russia did not receive a request by the official channels (2) Russia 'immediately' (сразу же) officially requested access to the chemical [sample], and to all facts concerning the investigation, since Yulia Skripal is a Russian citizen. We have received 'an inarticulate answer' (невнятный ответ), and the request was 'denied' (отказано) --Resup(talk) 12:37, 13 March 2018 (UTC)
 * An amendment: it is said (see below) that 'Novichok' has over a 100 variants, with chemicals composing a few of them published by Mirzayanov (who was out of the program in the 1990's and since emigrated and works in academia in USA). Thus, a few (alleged) compounds are known, but with details openly published by 2009, others can figure out how to synthesize those; also with the development being Soviet, not Russian, other former USSR republics may have it too. For the unpublished versions of Novichok, the above comment applies, one can say that anything not seen or rare, of a broad class, is Novichok, in one of those many unpublished versions. And no leaks on Russian (i.e developed after 1991), not Soviet compounds. Compare with Theresa May statement, 'military-grade nerve agent of a type developed by Russia', etc. Peter Wilson later statement uses same language. --Resup (talk) 05:33, 14 March 2018 (UTC)

 * Uglev, p.18: During the entire 15 years of my work in the laboratory, more than a hundred substances of this class were synthesized. Only five of them representing a significant "war interest" went through the full investigation. The dubious honor of discovering three of them  belongs to me.

 * ''Brief Summary: "Novicock" is not the name of the CW, but the cipher of the KGB operation to detect the channel of information leaks, as well as the supply of disinformation

I have seen this, but my impression is that this is essentially denial PR. Several people came forward, Mirzayanov not the only one; one scientist, Zheleznyakov, received accidental poisoning (and said to support those coming forward), two more people said to die after unauthorized use. Most of it is coming from Mirzayanov, but I do not have an impression that he is intentionally lying. Disinfo campaign, a possibility in principle, but with the development running for many years with many people involved, colleagues, students, etc not likely. The attitude at the time of his publications was that CW program is going to be abandoned and convention implemented (thus Merzayanov was released and allowed to leave to the West); and KGB was in weak position overall, seen as repressive. So over-the top major disinfo effort, with massive staging, is not very likely, and if it was felt that CW are to be abandoned, -not very meaningful. -Resup (talk) 03:38, 18 March 2018 (UTC)

I also found this interesting:
 * The curious case of the Salisbury poisonings - natsouth, March 17 2018
 * ''Maybe there is a possible connection between the development of Novichok as part of a Soviet CW programme, codenamed 'Foliant' and an long-defunct US FBI counter-intelligence project, codenamed “Operation Shocker”. This was a long-running US operation aimed at wasting Soviet resources & money in trying to develop a new super nerve gas the US believed unweaponizable, known as GJ, deemed to be an hopeless unachievable programme. The aim of the US operation was to misinform the Soviets about the US CW and BW programmes, through a fake 'defector'.

Wikipedia has an article on "Operation Shocker", but no one has linked it to novichoks.

Disinformation both ways? Or maybe the information was all real, and the story about the disinformation operation was invented after the real information had been leaked. -- Petri Krohn (talk) 14:33, 21 March 2018 (UTC)

Detection?
Novichok 5, and likely 7,8,9 are binaries, presumably mixed on the spot from precursors. Detecting presence of the agent as such should be doable (GC; MS; spectroscopy, Raman spectroscopy, NMR), and there may be tests developed to do it quickly, but detailed signature pointing to the origin (purity, impurities, by-products, etc) is difficult as it is mixed locally and detailed composition depend on the local mix. So they need to find a way to do it despite those local mix variations (and essentially detailing precursors, not the mix), and it is not clear whether they are capable of doing it reliably (and quickly enough). Also, this needs to be done on real samples taken from victims or the scene and so containing lots of contaminants not just the agent (unless they found true source of poisoning, unclear they did). --Resup (talk) 20:37, 15 March 2018 (UTC)

The convention says: synthesis of Schedule 1 chemicals for research, medical or pharmaceutical purposes, but not for protective purposes, may be carried out at laboratories in aggregate quantities of less than 100g per facility. But 100g should be enough for what happened, and those 100g may be produced afresh, not taken from a big batch of CW in industrial quantities. In that case, no signature, or it is at least very difficult, or impossible if there are no further clues to help. --Resup (talk) 18:26, 17 March 2018 (UTC)

Fentanyl
Fentanyl transdermal patches are available for pain control. So it can obviously cross the skin barrier but probably not quick enough to knock people out (incidentally I've had Fentanyl in medical procedures. It's not that active when administered topically)

There is a chemical derivative of Fentanyl Kolokol-1 which is gaseous and is alleged to have been used in the Moscow Hostage Crisis. It's possible, but probably ineffective in an open air setting --Charles Wood (talk) 08:53, 11 March 2018 (UTC)

Parathion
Parathion, an agricultural chemical, was used as a nerve agent in Rhodesia when it was impregnated on clothing to be picked up and worn by insurgents. Along with Thallium an estimated 1000+ insurgents were killed by these means. It works slowly enough to be considered a possible poison in the Skripal case - though what it was carried on is yet to be determined. --Charles Wood (talk) 18:28, 11 March 2018 (UTC)

Botulinum toxin
See also main page

I now suspect that Sergei Skripal and her daughter are suffering from botulism, caused by the "Risotto Pesce" they ate at the Zizzi restaurant. There was no "novichok agent" involved. The British investigators seem not to have a sample on the nerve agent. They do not know when and where it was administered to the Skripals. They have not identified the container used to transport it into the country or to the attack site. They have no suspects for the assumed attack. Maybe Yulia Skripal brought the nerve agent from Russia, but then it would need to have been in some container the police would have found by now.

Botulinum toxin is a neurotoxic protein with effects somewhat similar to those of nerve agents. It is the most acutely lethal toxin known, with an estimated LD50 of under 2 ng/kg intravenously. There is no evidence for the use of a nerve agent except the words of politicians, and maybe a reading on some mass spectrometer in Porton Down. For all I know the blip can be the result of random impurities, contamination of the environment around Porton Down or simple mass hysteria. -- Petri Krohn (talk) 21:06, 17 March 2018 (UTC)

Wrong Identification?
IMO, Botulinum toxin quite unlikely different mechanism and speed of onset, so I guess different symptoms, severity, treatment. Molecule is a protein monster compared to nerve agents, (here), and result is muscle tone weakness while for nerve agent a spasm. It also likely needs incompetence or outright falsification at Porton, and it's unlikely. I'd think there may be false positive bump on GC, less likely on mass spectrometry, ions mass to charge measurement is accurate and a misinterpretation or malfunction needed for this to go wrong; and spectroscopy is very accurate, so it will need a serious misinterpretation. But once they are serious onto confirming the theory, they can do all those tests, and failing them all is not going to happen. Also, they will test for everything, including bacteria, and will find botulinum bacteria. Does not mean that it's definitely fool-proof though, but needs something like this: (1) there is a pesticide out there with chemical structure close enough to pass all the tests which they actually had time to do, and it may be less testing then everything available as they were pressed with time and conclusions Seafood, especially farmed one, is the most polluted food out there, collecting everything. (Or maybe, as a theory, Porton Down somehow produces enough pollution to be detectable by Porton Down itself--Mirzayanov job in the USSR was to guard against similar issues)   (2) bacterial test did not come back yet. That may take weeks, up to a month, farming bacteria in a dish and counting. (3) something else, apparently more sudden and violent then 'normal' botulism, put the victims in their jeopardy, and (4) pretty many of people are eating stuff that looks like a nerve agent to the chemlab nerds --Resup (talk) 22:19, 17 March 2018 (UTC)

“Highly complex”
The Financial Times writes:
 * ''Clips of Mr Skripal’s car driving through Salisbury have been released, but no pictures of any individuals that are being sought.
 * ''A spokesperson for the Metropolitan Police said nothing should be read into this and that no information would be released unless it helps the “highly complex” inquiry.

“Highly complex” is a code word and means that normal legal and investigative procedures are not followed and the investigation should not endanger the predetermined outcome. -- Petri Krohn (talk) 12:06, 21 March 2018 (UTC)

Who is Ross Cassidy?
The name sounds awfully American. But other sources hint that Cassidy was Skripal's MI6 or MI5 handler in Britain. He was "a close friend of Sergei Skripal" and a close neighbor when Skripal rented his first house Salisbury. Ross Cassidy picked Yulia from the airport with his Japanese pick-up truck. Some sources said that this was his fists car after he arrived in the country. Where did he come from? Ireland or America? When? Note the formal and evasive language. Sounds like a police officer or an MI5 operative. -- Petri Krohn (talk) 15:56, 21 March 2018 (UTC)

 * Did treacherous past of Russian colonel finally catch up with him in Salisbury? - The Telegraph, March 6, 2018 (with photos, print version)
 * ''The colonel’s close friend Ross Cassidy, who lives just a few doors from the property the Russian rented when he first arrived in Salisbury, said he “was not at liberty to talk.”
 * ''He declined to say whether his friend had spoken of fears for his life, adding: “It’s a very sensitive investigation of some gravitas. I really am unable to divulge any information at the moment.”

Who was Joseph Edward Cassidy?
This may be just an odd coincidence, but is related to our study anyway.

In Operation Shocker started in 1959 U.S. Army First Sergeant Joseph Edward Cassidy leaked disinformation to the Soviets about U.S. chemical weapons programs. This might be his grave: command sergeant major (CSM) Joseph Edward Cassidy (1920-2011). Is Joseph Edward Cassidy in any way related to Ross Cassidy?

What is "weapons grade?"
The key factor in a weapons grade nerve agent is persistence, it does not evaporate - or as Vladimir Uglev describes them here, the chemical agents in the novichok series are "extremely tenacious." If the poison was a novichok or "weapons grade", then there should be residue where it was applied. How come the investigators have not found the spot of contamination? -- Petri Krohn (talk) 16:41, 21 March 2018 (UTC)

If it evaporates slowly, its concentration in the air is low, so it has to be effective at low concentration (and pure, as part of this). They also talk about cumulative effect with low exposure over long periods (so healing is slow/none). (But also, weapons grade may be not really defined, its whatever fits requirements set by the 'customer', and also not a DIY version of something better) --Resup (talk) 17:07, 21 March 2018 (UTC)

The key factors of weapons grade agents are that there must be a repeatable manufacturing process, a safe way of storing the chemicals with a militarily useful storage period, minimal risk to operators before deployment, a reliable means of delivery, and then depending on application either a long or short duration of activity after deployment. Nice to haves would be effective prophylactics and/or antidotes. Also, the agent should ideally create mass panic in victims or potential victims so as to multiply the casualties - psychological as well as physical. --Charles Wood (talk) 00:59, 22 March 2018 (UTC)

I guess this issue originates with Theresa May claim, It is now clear that Mr Skripal and his daughter were poisoned with a military-grade nerve agent of a type developed by Russia. But Russia destroyed its military-grade CW under OPCW control, around 1996. Claims of scientist were, if accurate at all, about development of CW, not mass production; they at most point at some other people having to do with mass production. But that mass production, even if it happened, was abandoned and destroyed. So Russia does not have weapon-grade nerve agents; as for small quantities, many countries could do it; but saying a small quantity is military-grade is meaningless --Resup (talk) 04:01, 22 March 2018 (UTC)
