Russia Warns NATO It Could Use Nuclear Weapons If Kaliningrad Is Isolated.

 

Russia has warned NATO that it could resort to nuclear weapons if the Western military alliance attempts to isolate Kaliningrad, the heavily militarised Russian exclave bordered by Poland and Lithuania.

The warning was contained in a diplomatic document sent to NATO and seen by Reuters, in which Moscow accused the alliance of pursuing a “dangerous and reckless course” that carried a high risk of direct armed conflict.

The document also warned that Russia could launch strikes against decision-making centres in NATO member states “right from the outset” of any conflict.

“Russia will be ready to use the entire arsenal of forces and capabilities at its disposal, including nuclear weapons, in order to defend its territory should NATO countries undertake any attempt aimed at isolating the Kaliningrad Region from the rest of the country,” the note stated.

The document was classified as a “non-paper”, a term used in diplomacy for an informal document that does not necessarily carry the status of a formal treaty or agreement.

Kaliningrad is a Russian territory on the Baltic Sea situated between NATO members Poland and Lithuania. The region hosts significant Russian military assets, including the Baltic Fleet and nuclear-capable Iskander missile systems.

Russia has accused NATO of increasing military pressure around the Baltic region and claimed it has information indicating that the alliance is preparing an air and naval blockade of Kaliningrad. Moscow has also rejected allegations that it intends to attack NATO countries.

Russian Foreign Ministry spokeswoman Maria Zakharova separately criticised what she described as “Russophobia” among Western officials and said Moscow’s warnings should be taken seriously.

NATO Secretary General Mark Rutte rejected the nuclear rhetoric, saying the alliance was defensive and urging Russia to stop issuing such threats.

“We are a defensive alliance. And stop the nuclear threats. This is absolutely not called for and not helpful,” Rutte said at a defence conference in Brussels.

When asked whether the Russian warning meant there was an imminent threat of nuclear weapons being used in the Baltic region, Rutte said there was not.

“No, it’s not. Putin knows that he can never win against NATO, so I don’t take this that seriously,” he said.

The exchange has heightened concerns over the risk of miscalculation in the Baltic region, particularly as NATO continues military activities in the area and European governments accuse Moscow of conducting hybrid operations, including sabotage and cyber activities. Russia has denied those allegations.

Nikolai Sokov, a former Russian diplomat and nuclear analyst, said the growing confrontation increased the risk that actions intended to remain below the threshold of war could instead be interpreted as acts of war.

The latest warning comes amid continuing tensions between Russia and NATO over the war in Ukraine and broader European security, with both sides publicly emphasising their respective military positions while accusing the other of escalating the situation.
