Finland plans to lift decades-old ban on hosting nuclear weapons

Why it matters: Finland's nuclear policy shift deepens NATO's deterrence against Russia, reshaping European security dynamics.
- Finland plans to amend its 1987 Nuclear Energy Act and criminal code to permit the import, transport, delivery, and possession of nuclear weapons for military defense.
- Defence Minister Antti Häkkänen stated the amendment is necessary for Finland to leverage NATO's deterrence and collective defense fully, given the changed security landscape since Russia's 2022 invasion of Ukraine.
- NATO's collective defense principle means an attack on one member risks a nuclear response, with US nuclear weapons already stationed in several European nations, according to the Center for Arms Control and Non-proliferation.
- Finland's government proposal, backed by its right-wing coalition, is undergoing consultation and is seen as a strategic response to Russia's actions and broader global instability, including alleged "hybrid warfare" incidents.
Finland plans to lift its decades-old ban on hosting nuclear weapons, a move its government says is crucial to fully integrate with NATO's deterrence strategy following Russia's invasion of Ukraine. This significant policy shift, driven by a "fundamentally and significantly changed" security environment, would allow nuclear weapons on Finnish soil for military defense, aligning Finland with other NATO members that host US nuclear arms.
