Finland has lifted its decades-long ban on nuclear weapons, marking a major shift in the NATO state’s foreign policy.

The country, which shares the longest border with Russia of any NATO member, passed the vote by 125 to 61 in parliament on Wednesday, clearing the way for Finland to facilitate the movement of nuclear weapons on its territory.

Finland banned nuclear weapons under its 1987 Nuclear Energy Act, prohibiting the import, manufacture, possession, and detonation of any such explosives on its soil.

“This historic reform strengthens the security of Finland and of NATO as a whole,” the country’s Defense Minister Antti Häkkänen wrote on X.
