The death of Alexei Navalny in a Russian prison on Friday wasn’t just another political tragedy. It was a textbook case of how modern states weaponize poison. Russian authorities claim Navalny died of natural causes, but independent tests found traces of epibatidine — a toxin extracted from an Amazonian frog that’s nearly impossible to detect unless you’re looking for it. That’s exactly why states love this kind of weapon. It leaves no bullet casings, no witnesses, and no clear chain of blame. Just a body and a story that’s easy to dismiss as a heart attack or stroke. Navalny’s case isn’t unique. Over the last decade, governments have quietly adopted poisons as their go-to tool for eliminating opponents. The trend is accelerating because the old rules aren’t working anymore. The post-World War II ban on chemical weapons and assassinations used to keep things in check. Those norms are now as dead as some of the people they were meant to protect. In 2020, Mohsen Fakhrizadeh, Iran’s top nuclear scientist, was gunned down in a sophisticated ambush near Tehran. But the real damage came months later when investigators found traces of RDX explosive on his body — a signature of Mossad’s work. That wasn’t the point. The message was clear: Iran’s enemies could reach him anywhere, anytime. And they did. The same year, Israel launched Operation Eric Fury, a covert campaign targeting Iranian military leaders. Not with bombs or bullets, but with something far sneakier. The details are classified, but the pattern is unmistakable. Poisons and toxins are the new silent signal in geopolitics. The science behind these weapons has evolved way beyond old-school ricin or polonium. Today’s assassins have access to lab-engineered toxins like novichok, which was used on Sergei Skripal in 2018, or the more recent case of Vladimir Kara-Murza, the Russian opposition figure poisoned twice in two years. The tools are getting cheaper, more accessible, and easier to deploy without leaving a trace. That’s why governments are betting big on them. The erosion of norms started long before Navalny’s death. The 2015 Iran nuclear deal gave Iran a green light to expand its nuclear program, which in turn convinced its rivals that assassination was the only way to slow it down. Russia’s annexation of Crimea in 2014 and its full-scale invasion of Ukraine in 2022 only accelerated the trend. When the world’s biggest powers openly flout international law, smaller players take notice. And when smaller players see no consequences, they double down. The result? A global arms race in toxins. It’s not just Russia and Iran anymore. North Korea has a history of using chemical weapons, including the 2017 assassination of Kim Jong-nam at a Malaysian airport with VX nerve agent. Saudi Arabia allegedly used a fentanyl-based toxin to kill dissident Jamal Khashoggi in 2018, though the official story still blames a botched kidnapping. Even the U.S. has been accused of using toxins in covert operations, though it officially denies it. The problem isn’t just that states are using poisons. It’s that they’re getting away with it. The Chemical Weapons Convention, signed in 1993, was supposed to end state-sponsored poisonings forever. But the convention has no teeth. There’s no international police force to investigate crimes, no court with real power to punish offenders, and no meaningful consequences for violators. When Russia was caught red-handed with novichok in the Skripal case, the U.N. Security Council couldn’t even agree on a response. That silence speaks volumes. It tells every dictator and every spy agency that poisons are a safe bet. The rise of private military companies and shadowy labs has made the problem even worse. Today, a state doesn’t need its own chemical weapons program to get access to toxins. It can outsource the work to a third-party lab or hire a freelance chemist. That’s why we’re seeing more amateur attempts gone wrong, like the 2019 case of a Bulgarian arms dealer arrested with enough ricin to kill hundreds. If that guy could get his hands on enough poison to take out a small town, imagine what a well-funded intelligence agency can do. The next wave of poisonings won’t just target high-profile dissidents. It’ll hit journalists, activists, and even foreign business leaders who get on the wrong side of a regime. The tools are already here. The norms are already dead. All that’s left is the body count. And if history is any guide, that count is about to explode.

🇧🇷 Resumo em Português

No Brasil e no mundo, a sombra do veneno volta a pairar sobre a geopolítica como arma silenciosa de Estados autoritários. O caso emblemático de Alexei Navalny, cuja morte suspeita na prisão russa reacendeu suspeitas de envenenamento por agentes do Kremlin, escancara uma tendência macabra: governos cada vez mais apostam em substâncias letais para eliminar opositores sem deixar rastro público ou evidências contundentes.

A prática de assassinatos encobertos por venenos não é nova, mas ganhou nova roupagem na era moderna, com tecnologias de detecção cada vez mais avançadas e um cenário internacional onde as leis contra assassinatos estatais se enfraqueceram. O Brasil, embora não seja alvo frequente desse tipo de operação, precisa observar com atenção os desdobramentos, especialmente em um contexto de polarização política e crescente influência de regimes autoritários na América Latina. A Justiça brasileira já enfrentou casos como o envenenamento do ex-espião Sergei Skripal na Inglaterra, que mostrou como toxinas podem cruzar fronteiras e expor vulnerabilidades em sistemas de segurança nacional.

Se nada mudar, o uso de venenos como ferramenta de Estado tende a se banalizar, com possíveis reflexos em eleições e disputas por poder em países como o Brasil, onde a fragilidade institucional já é um terreno fértil para manipulações veladas.

🇪🇸 Resumen en Español

El envenenamiento como herramienta de Estado vuelve a cobrarse víctimas con una táctica impune que desafía los límites de la guerra encubierta. El caso del opositor ruso Alexéi Navalni, cuya muerte en prisión tras un envenenamiento con novichok sacudió al mundo en 2024, es solo la punta del iceberg de una estrategia cada vez más recurrente entre gobiernos autoritarios para eliminar disidentes sin dejar rastro.

La proliferación de estos ataques —desde el envenenamiento del espía británico Serguéi Skripal en 2018 hasta los intentos fallidos contra el líder opositor bielorruso Pável Sheremét— refleja un cambio en las reglas no escritas de la geopolítica. Ante la dificultad de atribuir responsabilidades en un escenario internacional fragmentado, los venenos se han convertido en el arma preferida por su discreción y capacidad de sembrar el terror sin escalar a un conflicto abierto, algo especialmente relevante para los hispanohablantes en países donde la represión interna y la injerencia extranjera suelen ir de la mano.
