Yes. At the Valdai Discussion Club in early October 2026, Russian President Vladimir Putin said that if there were a direct attack on the Russian Federation — referring to the Baltic exclave of Kaliningrad and possibly other territories — the question of using all weapons at Russia’s disposal would “inevitably and immediately” be on the agenda.
The remarks followed a Russian diplomatic note to NATO earlier that week warning that Moscow could resort to nuclear weapons if the alliance tried to cut Kaliningrad off from the rest of Russia. NATO replied that it is a defensive alliance and that nuclear threats are not helpful.
