Finland moves to lift long-standing ban on hosting nuclear weapons

Finland has proposed removing a decades-old restriction that prevents nuclear weapons from being brought onto its territory, a move the government says would align Helsinki more closely with NATO's deterrence posture.
Under a law dating back to 1987, Finland forbids the import, manufacture, possession or detonation of nuclear explosives on its soil, even in wartime.
The government wants to revise that rule so nuclear arms could be present if they are used to support Finland's military defence within NATO. Defence Minister Antti Häkkänen said the change is needed to enable Finland to fully participate in allied defence planning and benefit from NATO's collective deterrence.
The proposal would alter both the Nuclear Energy Act and parts of the criminal code.
Finland's governing right‑wing coalition, which controls parliament, circulated the plan for public consultation until 2 April before submitting it formally. Lawmakers and public stakeholders are expected to debate the amendment once it returns to parliament.
The shift follows Finland's decision to abandon military non‑alignment and join NATO in 2023 after Russia's full‑scale invasion of Ukraine reshaped regional security.
Finland shares a 1,340 km border with Russia, the longest of any EU or NATO member, and leaders have warned the threat environment has worsened. NATO's collective‑defence guarantee rests in part on the nuclear capabilities of some member states, and U.S.
nuclear weapons are known to be stationed at bases in several European countries, according to arms control analysts.
In recent months, France and Germany have also signalled plans to strengthen cooperation on nuclear deterrence within Europe. The proposal comes as NATO boosts forces in the Arctic, the Baltic and along its eastern flank, and as Tallinn, Helsinki and other capitals respond to a pattern of incidents — including drone sightings that disrupted airports and bases last year — which some officials linked to hybrid operations.
If approved, the measure would mark a significant legal and strategic change for Finland, moving away from the neutrality‑era restrictions that governed its posture for decades.
The issue is likely to prompt intense domestic debate and attract close attention from allies and neighbours.
