When Russian President Vladimir Putin first announced the full-scale invasion of Ukraine in February 2022, his official video address was accompanied by thinly-veiled nuclear threats aimed at Western leaders. This Russian nuclear saber-rattling has remained a prominent feature of the war ever since.
Putin’s nuclear threats have made plenty of headlines but have only partially succeeded in deterring Western countries. For more than three and a half years, this strategy has helped Russia to slow down the flow of military aid to Ukraine without ever cutting off Western support entirely. Nevertheless, Kremlin leaders are seemingly unwilling or unable to abandon their nuclear scare tactics.
Putin himself frequently hints at possible nuclear escalation and has even officially revised Russia’s nuclear doctrine to lower the threshold for nuclear strikes. Meanwhile, Russian nukes have reportedly been deployed in Belarus, with Kremlin officials also recently threatening to supply nuclear weapons to Cuba and Venezuela. On November 5, Putin ordered Russian officials to begin preparations for the possible resumption of nuclear testing.
The Kremlin dictator is particularly fond of showcasing new weapons with nuclear capabilities. In late October, Putin announced the successful testing of the nuclear-powered and nuclear-capable Burevestnik missile. “This is a unique product that nobody else in the world has,” he commented. Days later, Putin hailed the similarly successful testing of the Poseidon drone, an atomic-powered and nuclear-capable underwater weapon. He trumpeted the Poseidon’s supposedly unmatched capabilities and stated that “there is no way to intercept it.”
It is impossible to independently assess the veracity of Putin’s claims or confirm the effectiveness of his latest alleged “wonder weapons.” Many have noted that neither weapon is entirely new, with the development of both being first announced back in 2018. In reality, the timing of these alleged tests is probably far more significant that the weapons themselves, and reflects Russia’s desire to engage in yet more nuclear saber-rattling.

Russia’s latest bout of nuclear posturing reveals much about Moscow’s frustration over continued Western support for Ukraine, and is likely a direct response to strong energy sector sanctions imposed in recent weeks by US President Donald Trump. It is a tactic that could eventually backfire on the Kremlin. By threatening to renew nuclear tests and boasting of unstoppable nuclear-capable wonder weapons, Putin risks highlighting Russia’s inability to project strength via more conventional means. In other words, the Kremlin dictator’s increasingly frequent use of nuclear blackmail may actually be a sign of weakness rather than strength.
Like a geopolitical gangster, Putin has come to rely on Mafia-style intimidation tactics as he seeks to reassert Russia’s great power status amid mounting evidence of his country’s steadily eroding military capabilities. Putin’s nuclear threats are at least in part an attempt to distract attention from the lackluster performance of the Russian army in Ukraine. While Russian forces currently hold the battlefield initiative and continue to advance, they have only managed to seize around one percent of Ukrainian territory over the past three years while suffering exceptionally high losses. This underwhelming outcome led Trump to brand Russia a “paper tiger” in September. The insult is believed to have struck a particularly raw nerve with Putin.

By brandishing his nuclear arsenal on the international stage, Putin aims to menace risk-averse Western leaders and deter them from opposing Russia in Ukraine. He also hopes to underline that victory over Ukraine remains Moscow’s overriding goal. Putin seeks to demonstrate his readiness to prioritize this quest for victory above all other considerations, including the nuclear deterrence system established over decades by Russia and the United States.
So far, Trump has offered a fairly robust reaction to Russia’s nuclear saber-rattling. This has included ordering US nuclear submarines to be moved closer to Russia in response to “provocative statements,” and indicating a readiness to resume nuclear testing “on an equal basis.” The US leader’s stance is a welcome sign that he is no longer easily swayed by Putin’s dramatics and recognizes the dangers of allowing himself to be intimidated.
Other Western leaders should now follow Trump’s example and acknowledge that the only way to bring Putin’s reckless nuclear blackmail to an end is by demonstrating resolve and reviving deterrence. This must include regenerating sufficient European and American conventional forces to deter Russia from attacking its neighbors. In parallel, sanctions on Putin’s war economy should be tightened, while Ukraine must finally be provided with the weapons its needs to defeat Russia’s invasion.
Nobody can afford to to take the risk of nuclear war lightly, of course. Nevertheless, it is unfortunately necessary to remind the Kremlin that Russia is not the only country with a nuclear arsenal. Genuine conventional and nuclear deterrence must be restored to deprive gamblers like Putin of the ability, let alone the desire, to employ nuclear blackmail in order to enable further acts of international aggression. Unless this is achieved, Putin will continue to use nuclear threats as a tool to intimidate his opponents and disguise Russian weakness.
