Fears are mounting that Russian President Vladimir Putin may consider the use of tactical nuclear weapons against Ukraine as peace negotiations have reached an impasse and Russian frustration intensifies, according to Kremlin sources cited by Bloomberg.
Voices within Moscow advocating for the deployment of nuclear warheads are reportedly growing louder, and Putin is exploring escalation options. Russia has become increasingly indignant about NATO allies supplying Ukraine with weapons and intelligence, leading to threats against the United Kingdom that Prime Minister Andy Burnham described as "outrageous."
Recent months have seen both Ukraine and Russia escalate attacks, with Kyiv launching significant strikes deep into Russian territory, including against oil infrastructure. The Kremlin, however, remains adamant that it will not end the war under pressure from sanctions or Ukrainian attacks on its refineries.
According to three Kremlin sources, Putin's conclusion is that he needs to intensify his attacks on Ukraine. He recently stated that Ukraine had "opened this Pandora’s box" and warned Kyiv to "Be ready to get a blowback on your most sensitive sectors of the economy."
While Russia is considering ramping up conventional ballistic assaults, including missile attacks on Kyiv, a growing number of Russian officials reportedly believe Putin could abandon the rules of modern warfare and deploy nuclear weapons. Tactical nuclear weapons, which are less powerful and have a shorter range than strategic missiles, would be more likely, intended to gain an advantage on a specific battlefield rather than destroy entire cities.
Throughout the conflict, Putin has repeatedly alluded to the threat of nuclear weapons against Ukraine and its Western allies. Fiona Hill, a senior fellow at the Brookings Institution and former national security advisor, emphasized the need for a "concerted collective and consistent effort to resist his actions, and to engage in diplomacy," noting Putin's "single-minded focus."
Separately, reports have surfaced this week suggesting Putin might be on the verge of testing a nuclear-powered cruise missile, codenamed the Burevestnik and nicknamed the "Flying Chernobyl." Analysts have observed increased aircraft and shipping activity in the Arctic, indicating a potential new experimental firing. This missile, described by Russians as having an "unlimited range," is designed to fly for days before striking targets.
The prospect of nuclear weapon use, while still considered remote, could only be definitively ruled out by a swift diplomatic resolution to the war, which currently appears out of reach. Russia has indicated a potential path to peace if Ukraine cedes control of key cities in the Donbas region, a proposal that Kyiv has rejected.
In June, U.S. Secretary of State Marco Rubio stated that if an agreement had been reached, the war would have ended. CIA Director John Ratcliffe made a rare visit to Moscow for a diplomatic meeting this week, though the focus of the discussions remains unclear. The United States is also reportedly preoccupied with the conflict in Iran.
