Russia Warns Finland Against Lifting Nuclear Weapons Ban, Signals Possible Countermeasures

Russia has issued a warning over Finland’s plan to lift restrictions on hosting nuclear weapons, saying such a move could be perceived as a direct threat to Moscow’s security. Kremlin spokesman Dmitry Peskov stated on March 6, 2026 that deploying nuclear weapons on Finnish soil would alter regional security dynamics and compel Russia to take countermeasures.

“By deploying nuclear weapons on its territory, Finland is beginning to threaten us,” Peskov said, adding that Moscow would respond with “appropriate measures” if the proposal is implemented.

Finland, which joined NATO in 2023, announced its plan to remove the decades-old nuclear weapons ban to align with the alliance’s deterrence strategy. Finnish Defence Minister Antti Hakkanen explained that the policy change would allow nuclear weapons to be brought into, transported, delivered, or possessed within Finland if necessary for national defense.

The Nordic nation ended its longstanding military neutrality upon joining NATO in April 2023, a decision influenced by Russia’s 2022 invasion of Ukraine under Vladimir Putin. Hakkanen noted that the security environment in Finland and Europe has “fundamentally and significantly changed and deteriorated” since the onset of the Ukraine conflict.

Relations between Helsinki and Moscow have also been tense due to Finnish accusations of Russian “hybrid warfare,” including allegedly directing migrants toward their 1,340-kilometre shared border—claims the Kremlin has denied.

The development marks a growing point of contention in Northern Europe, highlighting the ongoing security concerns between NATO members and Russia.
