Finland Lifts Nuclear Weapons Ban to Strengthen NATO Deterrence

The Parliament of Finland voted 125-61 on June 17, 2026, to lift a decades-long ban on nuclear weapons by amending the Nuclear Energy Act and the Criminal Code. The legislation permits the import, transport, supply, and possession of nuclear arms for national defense and cooperation with NATO. While President Alexander Stubb and the government stated there are no current plans to host nuclear weapons during peacetime, Prime Minister Petteri Orpo expressed interest in a French scheme to station nuclear-armed fighter jets at Finnish airbases.

This legislative shift follows Finland's abandonment of military neutrality after Russia's 2022 invasion of Ukraine. Defense Minister Antti Häkkänen characterized the reform as essential for national security and alignment with NATO allies. The decision comes amid heightened friction, including Finland's seizure of a Russian ship suspected of damaging an undersea cable and Russian allegations that Finland allows Ukrainian drones to attack Russian oil ports via its airspace.

Russia responded with sharp condemnation. President Vladimir Putin alleged that Finland joined NATO with the intent to seize Russian territory. Kremlin spokesman Dmitry Peskov warned the move escalates European tensions and stated Russia would take appropriate measures if threatened. Simultaneously, satellite imagery revealed a Russian military build-up along NATO borders, including new infrastructure in the Murmansk area and near the Estonian border capable of housing thousands of additional soldiers, as well as a new base near the Finnish border.
