Russia’s plague shouldn’t scare us – its secretive bioweapons should

**Lead**

Recent reports of bubonic plague cases in Siberia have stirred public anxiety, but security experts in London insist that the real threat from Moscow is not a medieval disease re‑emerging from the wild. Instead, the focus should be on Russia’s opaque and historically proven biological weapons infrastructure – a legacy of the Soviet Union that, according to declassified Western assessments, has never been fully dismantled. For the United Kingdom, which has invested heavily in biodefence since the Salisbury novichok attack, the prospect of a state‑sponsored biological strike remains a top‑tier national security concern.

**Contexto**

The Soviet Union ran one of the largest offensive biological weapons programmes in history, known as Biopreparat. At its peak, it employed tens of thousands of scientists and produced weaponised strains of anthrax, smallpox, plague, tularemia and other pathogens. After the Soviet collapse, Russia pledged to destroy its biological arsenal and allow international inspections. Yet Western governments have repeatedly accused Moscow of maintaining a covert programme. In 2018, the United States Department of State’s annual compliance report noted that Russia “continues to maintain an offensive biological weapons programme” and has “not fully declared” its past activities.

More recently, intelligence agencies have pointed to suspicious outbreaks near Russian military facilities. In 2019, a series of anthrax cases in the Yamal Peninsula were initially blamed on thawing permafrost, but some analysts questioned whether they were linked to a nearby Soviet‑era testing site. The Kremlin has consistently denied any violation of the Biological Weapons Convention (BWC), which it ratified in 1975. However, the UK’s own assessments, outlined in the 2023 Biological Security Strategy, highlight that “the risk of deliberate biological attack by a state actor remains low but credible”, with Russia singled out as a state that “retains the capability and intent to develop such weapons”.

For the United Kingdom, the concern is not merely historical. The Salisbury poisoning in 2018 demonstrated that Moscow is willing to use chemical agents on British soil. A biological attack – whether through a covert release of a pathogen or contamination of supply chains – could cause mass casualties and economic disruption. The UK’s Defence Science and Technology Laboratory (Dstl) at Porton Down has been working on rapid detection and countermeasures, but officials acknowledge that the sheer variety of potential agents makes complete protection impossible.

**Analise**

The current plague outbreaks in Russia, while alarming, are largely a natural phenomenon. Plague is endemic in the steppes of Central Asia and Siberia, and sporadic human cases occur every year. Modern antibiotics can treat it effectively, and the World Health Organization has not declared any international emergency. The real danger lies in the possibility that Russia could weaponise plague – or other pathogens – and deploy them in a conflict or as a tool of coercion. Unlike a natural outbreak, a deliberate release would be engineered to resist treatment, spread more efficiently, or target specific populations.

Why does this matter for the UK? First, the British intelligence community has long warned that Russia’s bioweapons programme is not just a relic of the Cold War. In 2022, the UK’s Chief of the Defence Staff, Admiral Sir Tony Radakin, stated that Russia’s “irresponsible behaviour” in the chemical and biological domain was a growing concern. Second, the war in Ukraine has provided a pretext for Russia to escalate its biological rhetoric. Moscow has repeatedly accused Ukraine and the West of operating biolabs – claims widely dismissed as disinformation – while simultaneously refusing to allow international verification of its own facilities. This pattern of denial and deflection is consistent with a state that has something to hide.

Moreover, the UK’s vulnerability is heightened by its dense urban population, reliance on global supply chains, and the ease with which a biological agent could be introduced via travel or trade. The COVID‑19 pandemic showed how quickly a novel pathogen can overwhelm the healthcare system. A state‑sponsored attack would likely be far more targeted and devastating. The UK government has therefore prioritised biodefence, investing in new vaccine platforms, genomic surveillance, and international cooperation through the Global Partnership Against the Spread of Weapons and Materials of Mass Destruction.
