The article reports growing concern that Vladimir Putin could escalate Russia’s war against Ukraine, potentially including the use of tactical nuclear weapons, as peace negotiations appear to have stalled. It says Moscow is increasingly frustrated by Ukrainian attacks on Russian oil infrastructure and by Western military support for Kyiv, while Russian officials are reportedly considering stronger conventional strikes first. The prospect matters because any nuclear use would mark a major escalation of the conflict and raise wider risks for Europe and Nato.

According to unnamed Kremlin sources cited by Bloomberg, Putin believes Russia must intensify its campaign and has warned Ukraine of repercussions against sensitive parts of its economy. Tactical nuclear weapons are described as shorter-range, lower-yield weapons intended for battlefield advantage, though the article says their use remains unlikely. It also cites analysts who believe Russia may be preparing to test the nuclear-powered Burevestnik cruise missile, while arguing that a diplomatic settlement is currently difficult to achieve.
