The Super Power Who Cries “Wolf”? Another Stern Russian Nuclear Warning, By Richard Miller (London)
The Kremlin's February 24, 2026, warning — issued on the fourth anniversary of Russia's full-scale invasion of Ukraine — centres on allegations from Russia's Foreign Intelligence Service (SVR) that the United Kingdom and France are covertly planning to supply Ukraine with nuclear weapons capabilities. Specifically, the SVR claimed London and Paris were preparing to transfer "components, equipment and technologies" to enable Ukraine to develop a submarine-launched ballistic missile carrying a thermonuclear warhead (or at minimum, a so-called "dirty bomb"). This, Moscow asserted, would give Kyiv leverage in ongoing U.S.-brokered peace negotiations, undermining efforts to end the war.
Kremlin spokesman Dmitry Peskov described the alleged plot as a "flagrant violation of all norms and principles of international law" and a direct threat to the global nuclear non-proliferation regime (centred on the NPT). He emphasised that Russia would "take [this] into account" in negotiations, framing it as leverage. Russia's upper house (Federation Council) echoed this, warning that under Moscow's nuclear doctrine, aggression by a non-nuclear state (Ukraine) backed by nuclear powers (UK/France) would be treated as a joint attack, potentially triggering retaliation.
The rhetoric escalated dramatically with Dmitry Medvedev (former president and current deputy head of Russia's Security Council), who declared that if such a transfer occurred, Russia "will have to use any type of weapon, including non-strategic nuclear weapons," against threatening targets in Ukraine — and implied proportional responses against the UK and France. President Vladimir Putin referenced related "nuclear element" risks in broader comments, warning adversaries of catastrophic consequences for crossing thresholds.
This fits a long-standing pattern of Russian nuclear sabre-rattling throughout the conflict: veiled threats to deter deeper Western involvement, often timed for maximum psychological impact (e.g., anniversaries, stalled talks, or arms package announcements). The claims arrived with no public evidence —no documents, intercepts, or verifiable intelligence — leading Western outlets and officials to label them disinformation or propaganda.
Western and Ukrainian Responses
France called the SVR allegations "blatant disinformation."
The UK (via spokespeople for PM Keir Starmer) rejected them outright.
Ukraine dismissed the accusations as "absurd lies," with President Volodymyr Zelenskyy linking them to Russian "political pressure" ahead of talks. He noted that when Moscow faces battlefield setbacks, it often fabricates nuclear pretexts (e.g., past "dirty bomb" claims in 2022). Zelenskyy has repeatedly prioritised NATO membership over nuclear rearmament, though he has mused that prolonged delays in security guarantees could force reconsideration of deterrence options — always framing it hypothetically.
Ukraine gave up the world's third-largest nuclear arsenal (inherited from the USSR) under the 1994 Budapest Memorandum, in exchange for security assurances from Russia, the US, and UK. Russia's invasion violated those assurances, fuelling Kyiv's distrust of non-nuclear status.
The Core Argument: Moscow's Real Intent
The warning isn't about credible intelligence of imminent nuclear proliferation — experts widely view the SVR claims as baseless, given the NPT's prohibitions (which UK/France, as nuclear states, are bound by) and the immense technical/political barriers to secretly arming Ukraine with deliverable nukes. Instead, it serves multiple Kremlin goals:
1.Escalation deterrence — Reinforce red lines to scare Western leaders from providing advanced weapons (e.g., long-range missiles, deeper strikes).
2.Leverage in talks — Use fabricated "nuclear threats" to extract concessions, portraying Ukraine/West as aggressors risking Armageddon.
3.Domestic/international narrative control — On the war's anniversary, shift focus from Russia's stalled advances, massive casualties, and economic strain to an existential "NATO-nuclear" peril justifying the invasion retroactively.
4.False-flag preparation — Some analysts (e.g., Institute for the Study of War) warn this rhetoric could prelude Russia staging or blaming a radiological incident on Ukraine to justify escalation or erode Western support.
In short, Zelenskyy (or any Ukrainian leader) using nukes against Russia remains a Kremlin-constructed boogeyman, not a realistic prospect. Ukraine lacks the infrastructure, fissile material, or delivery systems for an independent arsenal, and Western powers show no intent to violate non-proliferation norms by transferring warheads.
This episode underscores how nuclear rhetoric has become a routine tool in Moscow's arsenal: loud, unsubstantiated, and designed to paralyse rather than persuade. As peace talks limp along without territorial compromise, such warnings ensure the conflict's "abnormal normality" persists into its fifth year, with escalation always one crisis away.
