Putin's nuclear threats: What Russia's new strategy means for Ukraine

Russian President Vladimir Putin renewed nuclear threats against the West during his October 1 speech at the Valdai Discussion Club in Moscow, warning he would use the full arsenal, including nuclear weapons, in response to "Western aggression" and specifically citing the Kaliningrad exclave. Western experts say Putin's rhetoric is unchanged since the full-scale invasion and signals weakness, as nuclear threats indicate other methods have failed. They note NATO has no plans to isolate Kaliningrad, with transit through Lithuania continuing under controlled conditions, and dismissed the nuclear saber-rattling as intimidation. Analysts highlight Russia's escalating recklessness and sabotage campaigns across Europe, while noting Ukraine's defense remains relatively successful. They urge the West to maintain pressure through frozen Russian assets, sanctions enforcement, and preparation for potential threats, emphasizing that nuclear war must never be fought.
