The latest information that Russian opposition chief Alexei Navalny’s demise was attributable to epibatidine — a South American frog toxin — has reignited curiosity in state use of poisons and toxins in assassinations. Though state use of such compounds has a protracted historical past, the erosion of the norms prohibiting assassinations and chemical and organic weapons will increase the probability of future assassinations utilizing poisons and toxins. As demonstrated within the latest focusing on of the Iranian management in Operation Eric Fury and within the assassinations of outstanding Iranian nuclear scientists, together with Mohsen Fakhrizadeh, the assassination norm has collapsed. The norms towards chemical and organic weapons use, particularly in assassination, have weakened considerably to the purpose that toxins and toxins possible will turn into simply one other device within the murderer’s toolkit. Up to now, the anemic worldwide response to using poisons and toxins in assassinations ensures solely continued worldwide acquiescence.
The query then is, why do states use poisons and toxins to eradicate their opponents? Are these compounds in focused assassination meant to hide the act itself, or are they meant to sign hurt to those that oppose a regime? On Feb. 14, 2026, France, Germany, the Netherlands, Sweden, and the UK issued a joint assertion concluding that the demise of Navalny, which occurred on Feb. 16, 2024, throughout his incarceration, resulted from epibatidine. Analyses carried out in laboratories of those international locations confirmed the presence of the substance, which is prohibited below the Chemical Weapons Conference. This extraordinarily poisonous compound was most definitely synthesized by Russian scientists, thereby implicating the Russian authorities. Following this announcement, some have steered that using epibatidine in Navalny’s assassination was to “ship a message.”
This narrative is notably rooted within the profitable Russian assassination of former Russian intelligence officer Alexander Litvinenko in Nov. 2006, in addition to the 2 latest failed Russian assassination makes an attempt: The tried assassination of former Russian navy intelligence officer Sergei Skripal, which additionally affected his daughter, in Salisbury on March 4, 2018, and the tried poisoning of Navalny throughout a flight to Moscow on Aug. 20, 2020. The collection of this agent contributed to the notion of Novichok as a particular “Russian signature” deployed by Moscow to sign intent, whereas reinforcing a story inserting Russia on the middle of state use of poisons and toxins in assassination. Taken collectively, using uncommon or uncommon supplies has led some to recommend that messaging was a aim.
Nevertheless, neither the Litvinenko assassination, the 2018 Skripal try, the 2020 Navalny try, nor the profitable 2024 Navalny assassination helps this interpretation. A better look means that the first goal was the elimination of an opposition determine with out detection or attribution and never theatrical signaling. The historic document of state assassinations additional helps this conclusion. It due to this fact requires renewed consideration to why states favor poisons and toxins in focused assassination and to the extent to which different states, past Russia, might have interaction in comparable covert operations.
Skripal and Navalny instances: From “Signature Novichok” to Invisible Epibatidine
Skripal allegedly spied for British intelligence and was arrested and imprisoned in Russia in 2006. Following the 2010 spy swap, Skripal was resettled by British authorities in Salisbury, England, the place he lived till he turned the sufferer of a Novichok assassination try. On the morning of March 4, 2018, Skripal left his dwelling along with his daughter, who had flown in from Moscow the day earlier than to go to him, unaware that the outside door deal with had been contaminated with Novichok in an try and kill him. After initially leaving, his daughter, Yulia, briefly reentered the home, additionally coming into contact with the contaminated deal with and changing into uncovered to the nerve agent. Each had been discovered unconscious on a bench in central Salisbury. They had been rushed into emergency care and survived after intensive medical therapy. Subsequent analyses carried out by the Organisation for the Prohibition of Chemical Weapons laboratories confirmed using Novichok. Clearly, Skripal was the only goal, and Yulia was uncovered solely as a result of the assassins failed to think about her reentry into the home.
Navalny was probably the most outstanding critic of Vladimir Putin. On Aug. 20, 2020, earlier than boarding a flight from Tomsk to Moscow, Navalny’s clothes in his resort room in Tomsk was contaminated with Novichok. As he turned gravely ailing quickly after takeoff, the plane made an emergency touchdown in Omsk, the place he acquired preliminary emergency care. He was subsequently medically evacuated to Germany, the place he underwent intensive therapy. Laboratory analyses later confirmed Novichok poisoning.
After recovering, Navalny accused Putin of accountability and implicated Russia’s Federal Safety Service. Navalny returned to Moscow in 2021 and was instantly arrested and imprisoned. After a number of convictions, he remained in custody till he was discovered lifeless in his jail cell on Feb. 16, 2024. Russian authorities attributed Navalny’s demise to “sudden demise syndrome,” a broad time period for abrupt cardiac arrest. Close to the second anniversary of his demise, 5 European international locations issued a joint assertion accusing Russia of poisoning him with epibatidine. This conclusion was solely potential after a concerted effort by Navalny’s household and associates to smuggle samples out of Russia. Had they been prevented from doing so, a definitive explanation for demise would have remained unknown.
In all three instances, one narrative has been that Russia employed unique compounds to “ship a message” (i.e., theatrical homicide) to its opponents. Nevertheless, nearer examination suggests in any other case. Consciousness of those poisonings resulted from operational failures, together with circumstances that prevented rapid lethality and allowed using poison to be detected and investigated. Proof highlights that the dose within the 2020 Navalny case was deadly and his survival apparently resulted from unanticipated components. In each the Skripal and the primary Navalny makes an attempt, had the brokers produced speedy demise, the precise trigger possible would have been obscured. Yulia Skripal’s unintended Novichok publicity, nonetheless, enabled speedy detection in the UK, adopted by laboratory affirmation. Notably, the primary responders in Salisbury initially suspected the Skripals had been struggling a drug overdose. Likewise, in Navalny’s case, the poisoning was confirmed solely as a result of he was medically evacuated to Germany. If the dosage had been right and Navalny had not acquired immediate emergency care, he possible would have succumbed on the airplane or shortly after touchdown. On this state of affairs, he wouldn’t have been taken to Germany, the place Novichok was found in his physique.
The sample applies to the 2024 Navalny assassination. If the target had been to supply a visual and attributable sign, using a signature agent equivalent to Novichok would have been extra constant than the selection of a nonclassical and weakly traceable toxin, provided that laboratories would have examined for Novichok first. Russian authorities additionally possible didn’t anticipate that organic samples can be transferred overseas and analyzed in Organisation for the Prohibition of Chemical Weapons laboratories.
In practically each case, claims that messaging or theatrical homicide fail the parsimony take a look at. Merely, the messaging-only speculation requires too many unvalidated, unsupported assumptions. The precept that assassinations’ major goal is the demise of the goal (death-only) is parsimonious. Probably the most parsimonious clarification is that, whereas demise is the first aim, messaging generally is a second- or third-order impact, particularly if the operation is found as a result of the operation has failed.
Historic File of State-Sponsored Chemical Weapons Assassination
The narrative that Moscow seeks to “ship a message” additionally tends to forged Russia because the state most related to chemical weapons assassinations. Latest historical past, nonetheless, exhibits that using poisons and toxins in assassinations has been much more widespread. Since 1946, at the very least 16 states have been documented as having deliberate or tried poison or toxin assassinations, with over 100 recognized incidents in whole. These instances contain each authoritarian and democratic regimes, together with the Soviet Union (from the late Nineteen Forties to the Nineteen Eighties), the UK (Fifties), the United States (Sixties), France (Fifties to the Sixties), Israel (Fifties to the 2000s), Czechoslovakia (Fifties to the Nineteen Seventies), Yugoslavia (Sixties), East Germany (Nineteen Seventies), Bulgaria (Nineteen Seventies), Chile (Nineteen Seventies), Rhodesia (Nineteen Seventies), Iraq (Nineteen Seventies to the Nineties), apartheid South Africa (Nineteen Eighties to the Nineties), Iran (Nineties), Russia (2000s to the 2020s), and North Korea (2017). The recourse to those compounds in focused assassination is due to this fact not ideologically particular however stems from the properties of the weapons themselves.
These documented instances span a number of phases of assassination operations — from planning and preparation to tried assassinations, together with the 2018 Skripal and 2020 Navalny poisonings, by means of to profitable killings equivalent to Navalny’s demise in 2024. Such operations differ in type and technique, starting from political homicide and extrajudicial killing to covert assassination. Their major rationale, nonetheless, stays the elimination of regime opponents, with out the potential for tracing accountability again to the state. These instances immediately contradict the theatrical narrative usually related to latest Russian poison and toxin assassination operations.
This logic is most clearly illustrated by apartheid South Africa, probably the most extensively documented case of state assassinations utilizing poisons and toxins to this point, with 27 recognized operations, broadly similar to the mixed Soviet and Russian document. Analysis carried out inside apartheid’s chemical and organic warfare program, Undertaking Coast, exhibits a sustained give attention to the weaponization of chemical weapons brokers and supply strategies designed to make sure covert lethality, a natural-appearing explanation for demise, and believable deniability, together with toxins hid in on a regular basis objects equivalent to umbrellas, screwdrivers, cigarettes, and meals or drink containers. Additional examination of recognized chemical weapon assassination operations, even when most can’t be immediately linked to Undertaking Coast, signifies that they had been conceived to preclude attribution to the apartheid regime. That is illustrated by the poisoning of clothes overseas within the failed assassination makes an attempt towards former head of the Dutch anti-apartheid motion Conny Braam in Lusaka and Harare (1987), for which the agent stays unknown, and the confirmed poisoning of Reverend Frank Chikane’s belongings on the airport in Johannesburg, which brought on him to fall ailing outdoors the nation, first in Namibia after which in america (1989), mirroring the 2020 Navalny case.
Apartheid-era political responses, as soon as such instances turned public, combining denial with intimidation or retaliation, additional illustrate this concealment logic, as within the story of anti-apartheid scholar activist Siphiwo Mthimkhulu, poisoned with thallium in jail custody in 1981. After his launch, he found he was poisoned, prompting a public marketing campaign and authorized motion towards authorities. He was, nonetheless, shortly thereafter, kidnapped and killed by the safety police, suggesting an effort to suppress publicity of his poisoning.
Traditionally, these assassination operations have not often been publicly acknowledged by the states concerned. Nearly all recognized operations have come to gentle by means of operational failures, together with dosing errors that go away victims alive and in a position to report their sickness. Brokers have then usually been recognized or confirmed by means of overseas medical evaluation of organic samples, as in Russian instances, but additionally in apartheid-era instances equivalent to these of Mthimkhulu (United Kingdom) and Chikane (United States). Past operational failures, data of Soviet and apartheid South African chemical weapons assassination packages and related operations derives largely from recorded testimony, notably that of Soviet defectors and post-apartheid inquiries into Undertaking Coast carried out by the Fact and Reconciliation Fee. The US use of poisons and toxins was not revealed till the 1975 Church Committee, greater than a decade later.
Profitable operations, against this, go away little hint or are troublesome to research: Victims will not be believed, poisoning might go unsuspected, issue of diagnoses, organic samples might by no means be obtained, collected too late, or the sufferer finally dies with out suspicion. The aim is, as one writer has described it, a “silent demise,” or as a French paper on assassination described it, pas vu, pas pris (“not seen, not achieved”). This sample means that documented instances characterize solely a fraction of state assassinations utilizing deadly compounds, and that each poisonings quantity and the variety of states concerned is more likely to be far greater.
Motivations Behind State-Sponsored Chemical Weapons Assassination
As soon as the argument that states resort to those compounds in focused assassinations to “ship a message” is put aside, it turns into potential to look at the components that will encourage a state to make use of such weapons in these assassination operations.
First, a state might resort to poisons and toxins for operational benefits. Owing to their intrinsic properties, they permit covert focusing on with troublesome detection, as these compounds are silent, odorless, and colorless, and might be delivered by means of on a regular basis, dual-use contact vectors equivalent to private gadgets, meals, or on a regular basis objects. This allows assaults towards laborious targets, together with well-defended or in any other case inaccessible people, usually in non-permissive safety environments. Chemical weapons also can produce delayed scientific results, mimic pure sickness, or create natural-appearing causes of demise, hindering detection and permitting demise to happen outdoors the territory of the accountable state.
Second, such assassinations supply vital benefits by way of deniability and attribution. As a result of the reason for demise is commonly extraordinarily troublesome to determine with certainty, using such weapons can obscure political accountability and facilitate denial. Finally, the target is for the demise to seem pure and devoid of obvious political which means.
Third, victims might not suspect poisoning or, worse, will not be believed, owing to the perceived implausibility of such an assault. Even when suspicion arises, establishing publicity requires well timed entry to specialised laboratories able to applicable evaluation, usually restricted to Organisation for the Prohibition of Chemical Weapons-designated amenities.
Fourth, delayed results permit the assassins to flee arrest and interrogation by legislation enforcement on the scene. We have now seen this lately within the Litvinenko and Skripal instances.
Lastly, restricted political penalties might encourage states to resort to using poisons or toxins in assassination. Weakening worldwide prohibitions, together with below the Chemical Weapons Conference and the Organic Weapons Conference, have lowered deterrence, largely as a result of the results of poison use are negligible and short-lived. Worldwide responses are usually confined to diplomatic expulsions or symbolic sanctions with few tangible penalties for the accountable state.
Wanting Forward: The Enduring Enchantment of Deniable Poisons and Toxins Use by States
Given the motivations outlined above, it’s more and more possible that an rising variety of states might sooner or later resort to those compounds in focused assassination operations, particularly within the context of rising transnational repression.
Historic precedents of deniable assassination operations utilizing poisons and toxins might themselves encourage additional state adoption. As defined above, these compounds have been employed in these operations by each authoritarian and democratic regimes. At current, a number of states throughout regime sorts are suspected of sustaining analysis and growth actions associated to chemical warfare, elevating issues about their potential use in state-sponsored assassination within the expectation of minimal threat of arousing suspicion, unlikely attribution, and perceived deniability. The restricted penalties noticed in previous instances might additional enhance the perceived attractiveness of such strategies. That is bolstered by the Navalny case, which has produced few significant repercussions, following the Feb. 2026 announcement.
This restricted response to Navalny’s demise is embedded in a wider normalization of state non-compliance with worldwide legislation and the rising use of arbitrary state practices, which can additional enhance the enchantment of poison or toxin use in state assassination operations. The erosion of the norms prohibiting using chemical and organic weapons has been demonstrated throughout a number of contexts, together with the use or alleged use of chemical weapons in latest intrastate conflicts (Syria, Georgia) and interstate conflicts (Ukraine, Sudan), additional reinforcing this broader normalization of their use. The enchantment of chemical weapons use is probably going additional deepened by a permissive worldwide surroundings characterised by the intensification of armed conflicts, renewed technologically pushed arms competitors, and the weakening of peace and safety mechanisms.
Modern scientific and technological advances might also enhance the enchantment of poison use in assassinations to states. Developments in chemistry and biotechnology, along with rising supply strategies, together with drones, the proliferation of dual-use supplies and applied sciences, the democratization of scientific data and analysis infrastructures, and the rising use of synthetic intelligence, might decrease technical and operational limitations to the formulation and covert deployment of poisonous brokers.
Conclusion
The narrative that Russia resorted to poisonings within the 2018 Skripal, 2020 Navalny, and 2024 Navalny assassination makes an attempt and killings to “ship a message” is extremely questionable. Information of those operations has derived primarily from operational failures and the next evaluation of organic samples in Organisation for the Prohibition of Chemical Weapons laboratories. Russia’s use of poisons in these focused assassinations is greatest defined by the capability of those weapons to allow concealment and obscure attribution. Historic instances, significantly apartheid South Africa, corroborate this sample.
Furthermore, such practices will not be confined to Russia however have traditionally been employed by each authoritarian and democratic regimes. Within the present worldwide context, characterised by weak deterrence, norm erosion, and the widespread suspicion of state chemical and organic weapons capabilities, the prospect of extra frequent state recourse to poisons in assassination is due to this fact a rising concern.
Past chemical weapons, dangers might also prolong to organic ones. Advances in biology and genetic engineering elevate the likelihood that states may, sooner or later, contemplate biologically derived or engineered brokers able to rising selectivity, decreasing uncontrolled unfold, and producing types of illness that might be much more troublesome to attribute. Such developments would additional improve the enchantment of deniable chemical or organic brokers to states to be used in covert state-sponsored assassination.
