Finland Lifts Nuclear Weapons Ban, Aligning Legal Framework with NATO Deterrence

Finland’s parliament approved an amendment to the 1987 Nuclear Energy Act, repealing the blanket ban on import, transport, supply and possession of nuclear weapons for national defence. The vote recorded 125 in favour, 61 against, and 13 abstentions.

Adopted during the Cold War to preserve neutrality after the Continuation War, the 1987 act barred nuclear weapons. Finland joined NATO in April 2023 following Russia’s invasion of Ukraine, prompting a reassessment of its defence posture.

Defence Minister Antti Häkkänen led the proposal, calling the reform essential for security. President Alexander Stubb’s administration supported it. Opposition parties—the Social Democrats, Greens and Left Alliance—objected. Polls show 77 % opposed stationing nuclear weapons (July 2023) and only 18 % supported deployment (May 2026).

The amendment allows Finland to host or transit nuclear weapons if NATO deems it necessary, potentially integrating Finnish air bases into NATO’s nuclear sharing. Finland’s 64 F-35A fighters could, if certified, carry U.S. B61-12 dual-capable bombs, though no such role has been approved.

Finnish officials stress the law does not create immediate nuclear deployment and that Finland “does not need nuclear weapons in peacetime.” Kremlin spokesman Dmitry Peskov called the decision an escalation that threatens European security and warned of “appropriate measures.”

Opposition lawmakers warned the amendment could make Finland a primary target and breach regional norms, noting neighboring states have refused nuclear hosting. Environmental groups and left-wing parties criticised the lack of broad consensus and feared heightened tensions with Russia.

Sources differ on the vote date—some cite 17 June 2026, others 24 June 2025 or 17 June 2025. While Finland asserts no immediate deployment, the amendment permits future transit or hosting, leaving implementation details unclear. No NATO or U.S. comment has been reported.

After presidential assent, the amendment will align Finland’s legal framework with NATO’s nuclear deterrence. The government plans to decide on participation in French President Emmanuel Macron’s European nuclear umbrella initiative by autumn. Ongoing Russian military activity near the border suggests the policy will remain a focal point of European security debates.
