Russia Warns NATO of Nuclear Response if Kaliningrad Is Isolated

Russia has warned NATO that it is prepared to use its full arsenal, including nuclear weapons, if the alliance attempts to isolate Kaliningrad, according to an informal document conveying the warning.

The message also raised the prospect of strikes against NATO’s decision-making centres, linking that threat to any effort to cut off the region.

The warning framed Moscow’s readiness to use force as conditional on action against Kaliningrad. It did not describe such an operation by NATO as already under way.

The use of an informal document leaves questions about the warning’s official status. The available account provides no details about who drafted it or how it was delivered to the alliance.

No NATO response was included in the account, nor were details given about what specific measures Moscow would regard as an attempt to isolate Kaliningrad.
