Russia Warns NATO of Nuclear Option Over Kaliningrad Isolation

Russia has warned NATO that it would be prepared to use its “entire arsenal,” including nuclear weapons, if alliance members tried to isolate Kaliningrad from the rest of Russian territory.

The warning links the possible use of nuclear force to a specific scenario involving the Russian exclave. It presents any attempt to cut off Kaliningrad as a potential trigger for a confrontation extending beyond conventional military action.

Kaliningrad’s separation from Russia’s main territory makes access to the exclave a sensitive security issue for Moscow. The threat places that access at the centre of a stark warning to the Western alliance.

The statement was conditional, addressing what Russia might do if NATO countries attempted such isolation. The available account does not establish that an attempt was under way or that Moscow had taken steps to deploy nuclear weapons in response.
