Five European Governments Declare Epibatidine Poisoning of Navalny, Move to OPCW

State use of exotic poisons to silence dissidents has grim precedents: Bulgaria’s 1978 ricin-umbrella killing of Georgi Markov in London, Russia’s polonium-210 murder of Alexander Litvinenko in 2006, and the Novichok attacks on Sergei Skripal in 2018 and Navalny himself in 2020. Each incident tested global arms-control regimes born after the 1915 chlorine clouds of Ypres and codified in the 1993 CWC. Today’s accusation fits a long trend: great-power security services turning to rare or synthesized toxins that leave distinctive signatures yet offer deniability. Whether epibatidine joins “Novichok” as shorthand for Kremlin tradecraft or fades like Cold-War mysteries will shape the century-long struggle to reinforce the norm that chemical weapons are beyond the pale. The moment matters less for immediate battlefield dynamics than for the slow erosion—or entrenchment—of the post-World-War-II taboo against state chemical assassination; repeated breaches without effective penalties can, over decades, normalise the practice and hollow multilateral institutions such as the OPCW.
