Russia Warns NATO Over Kaliningrad, Mentions Nuclear Arms

In October 2026, Russian President Vladimir Putin said Russia would use "all types of weapons" if Kaliningrad were attacked, and that Russia may use its full arsenal in such a case. Russian officials also said Russia would retaliate swiftly if NATO carries out threats against the Kaliningrad region. The Kremlin said a letter sent to NATO about Kaliningrad was not confrontational, and Putin said the letter was not intimidation. Nikolai Patrushev also commented on the response to what was described as NATO aggression against Kaliningrad.
