Putin Says Russia Could Use Nuclear Weapons if Kaliningrad Is Attacked

MOSCOW — Russian President Vladimir Putin has warned that Moscow could consider using every type of weapon available to it, including nuclear arms, if Russia were subjected to a direct attack involving Kaliningrad, the heavily militarized Russian exclave on the Baltic Sea between Poland and Lithuania.

Putin made the remarks on October 1 during the annual Valdai Discussion Club forum in Moscow. His comments came amid a sharp exchange between Russia and NATO over military activity in the Baltic region, Russian claims that the alliance could try to isolate Kaliningrad, and a written warning that Moscow recently sent to NATO.

The central point of Putin’s remarks was conditional. He did not announce that Russia had decided to use nuclear weapons, nor did he describe nuclear use as imminent. Instead, he said that if there were a direct attack on the Russian Federation, including Kaliningrad or another Russian territory, the use of all weapons in Russia’s arsenal would immediately become a question for consideration.

Putin told the forum that in such a scenario, “all weapons at our country’s disposal” would be on the agenda. He also said Russia had no plan to attack a European country and argued that Moscow was responding to what it considers Western escalation rather than preparing an offensive against NATO.

The warning followed a diplomatic message from Russia to NATO that raised the possibility of nuclear retaliation if the alliance attempted to cut Kaliningrad off from the rest of Russia. Reuters reported that NATO had received the message and that Moscow presented it as a response to what it views as a growing threat to the exclave.

Kaliningrad occupies an unusually sensitive position in European security. The territory is separated from mainland Russia and lies between NATO members Poland and Lithuania. It hosts Russia’s main Baltic naval base along with other military assets. The Associated Press has reported that nuclear-capable Iskander missile systems are deployed there.

Russia has accused NATO of increasing pressure on Kaliningrad through military exercises in the Baltic Sea and other allied activity in the region. Russian embassies in Europe have claimed that NATO is preparing for a possible air or naval blockade of the territory. Moscow has not publicly produced evidence establishing that NATO has adopted such a plan.

NATO has rejected the Russian characterization. In an official September 30 interview, NATO Secretary General Mark Rutte said the alliance had responded to Moscow by emphasizing that NATO is defensive and by telling Russia to stop making nuclear threats. Rutte also said there was no imminent threat to NATO territory and that the alliance would be able to detect and respond to a major Russian military buildup against one of its members.

NATO spokesperson Allison Hart separately said the alliance strongly denounced threats of force and irresponsible nuclear rhetoric. According to the Associated Press, NATO told Russia that its activities and exercises do not pose a threat to Kaliningrad or other Russian territory.

The confrontation is unfolding against the wider background of Russia’s war in Ukraine, now in its fifth year. NATO members continue to support Ukraine with military and financial assistance, while Russia argues that Western weapons, intelligence and long-range strike support are increasing the danger of a direct confrontation between Moscow and the alliance.

Putin used his Valdai appearance to argue that repeated cycles of retaliation can become difficult to control. Reuters reported that he warned of a point at which escalating measures could produce consequences that governments could no longer reverse. At the same time, he continued to defend Russia’s military position and said Moscow would use what he described as its strategic advantages if it faced a direct conflict with NATO.

The Russian president also acknowledged the nuclear capabilities of Britain and France, both NATO members. His remarks emphasized Russia’s own advanced weapons systems and presented them as a deterrent against an attack on Russian territory.

NATO’s nuclear posture also remains part of the broader strategic picture. The alliance states that its deterrence policy relies on a combination of nuclear, conventional and missile-defense capabilities and says its nuclear forces exist to deter aggression. NATO has simultaneously condemned what it describes as coercive Russian nuclear signaling.

The latest warning therefore adds to an already tense security environment around the Baltic Sea without establishing that either Russia or NATO has decided to initiate a direct military confrontation. The most consequential issue is the gap between the two sides’ descriptions of the same activity: Moscow portrays NATO exercises and regional security measures as preparation for possible isolation of Kaliningrad, while NATO says those activities are defensive and that it has no intention of attacking Russian territory.

That distinction matters because both Russia and NATO possess nuclear forces. A military incident involving Kaliningrad, Poland, Lithuania or the Baltic Sea could therefore carry risks far beyond the immediate area if either side interpreted the other’s actions as the beginning of a broader attack.

For now, Putin’s statement remains a conditional warning tied to what Moscow defines as a direct attack on Russian territory. NATO has publicly rejected the premise that it is threatening Kaliningrad, while continuing military exercises, reinforcement and support for Ukraine. The exchange underscores how quickly disputes over exercises, maritime activity and access to the Baltic exclave can become entangled with nuclear deterrence.
