Europe Fears Russia May Use Chemical Weapons in Ukraine During a Prolonged War

Summarized by NextFin AI
  • European security agencies and Ukrainian military intelligence warn of Russia's potential escalation using chemical weapons, particularly as the conflict enters a protracted phase.
  • Russian forces have reportedly used hazardous chemicals over 9,000 times since the invasion, with 6,540 instances in 2025 alone, including prohibited agents like chloropicrin.
  • The strategic implications of using lethal chemical weapons could incur massive international costs for Russia, despite minimal military gains.
  • The normalization of low-level chemical usage may lower the threshold for deploying nerve agents like Novichok, posing a significant challenge to global weapons prohibitions.

NextFin News - European security agencies and Ukrainian military intelligence have sounded a high-level alarm regarding the potential for Russia to escalate the ongoing conflict through the use of lethal chemical weapons of mass destruction. According to a report by The Times published on January 25, 2026, Western officials fear that as the war enters a protracted phase of attrition, U.S. President Trump’s pressure for a ceasefire may inadvertently push the Kremlin toward unconventional warfare to break the battlefield deadlock.

The scale of chemical usage has already reached alarming levels. Data from the Ukrainian military indicates that Russian forces have employed hazardous chemical substances over 9,000 times since the invasion began, with 6,540 instances recorded in 2025 alone. These attacks primarily involve grenades filled with riot-control agents such as CS and CN gases. However, European officials have documented the occasional use of chloropicrin—a choking agent first utilized in World War I—which is strictly prohibited under the 1993 Chemical Weapons Convention and the 1925 Geneva Protocol.

The deeper concern lies in Russia’s more sophisticated arsenal. Investigative groups, including Bellingcat, have previously concluded that Russia’s 'Novichok' nerve agent program continued long after its officially claimed closure. Research centers like 'Signal' and the State Institute of Experimental Military Medicine are suspected of maintaining the capability to weaponize these agents. Hamish de Breton-Gordon, a former British Army officer and chemical weapons expert, noted that if Novichok were deployed on a broader scale, the humanitarian and strategic consequences would be 'colossal.'

From a strategic perspective, the potential shift to lethal chemical weapons represents a 'double-edged sword' for Moscow. General Sir Richard Barrons, former commander of the UK Joint Forces Command, argues that such a move would bring minimal military gain while incurring massive international costs, including the risk of exposing Russian troops to their own agents if wind directions shift. However, Barrons warned that the temptation to use such weapons arises when 'the stakes are extremely high and the survival of the regime is perceived to be at risk.'

The timing of these fears coincides with a complex diplomatic landscape. U.S. President Trump has been actively brokering trilateral talks in Abu Dhabi involving Russian and Ukrainian envoys. While the White House has described these discussions as 'productive,' the Kremlin has maintained a rigid stance, demanding full control over the Donbas region. Analysts suggest that if these U.S.-led peace efforts fail to deliver the territorial concessions sought by Vladimir Putin, the Russian military may resort to chemical escalation to force a Ukrainian collapse before Western industrial production can fully replenish Kyiv’s dwindling ammunition stocks.

Looking forward, the trend suggests a dangerous 'normalization' of low-level chemical usage as a precursor to more lethal applications. If the international community fails to impose significant consequences for the documented use of chloropicrin and riot-control agents in combat, the threshold for using nerve agents like Novichok will continue to lower. For Europe, the threat is not merely a localized battlefield issue but a fundamental challenge to the global prohibition of weapons of mass destruction, potentially reshaping the security architecture of the continent for decades to come.
