The decades-old policy was overturned with more than two to one voting in favor.
Living next to a powerful and aggressive neighbor forces a country to rethink its oldest rules.
For decades, northern Europe maintained a delicate balance of neutrality to keep the peace.
But a shifting security landscape is now driving one Nordic nation to make a radical choice about its defense.
A historic shift
On Wednesday, lawmakers in Finland acted decisively by reshaping the nation’s military posture. The country’s parliament voted 125 to 61 to overturn a decades-old prohibition against holding nuclear weapons on its soil, Bloomberg and Euronews report.
The decision marks a major turn for the newest NATO member. Under the previous 1987 Nuclear Energy Act, written during the Cold War, importing or transporting nuclear devices was strictly illegal.
The updated law removes that blanket ban specifically for national defense. However, actually manufacturing or setting off nuclear weapons within the borders remains a criminal act.
The Kremlin has not yet reacted to the result of the vote.
Deterrence not deployment
Bloomberg reported that the government intends to use the law change to scare off potential adversaries. Officials clarified that they have no immediate plans to actually host any atomic weapons.
Even so, the policy alignment allows for deep integration with Western allies. Defense Minister Antti Hakkanen praised the decision on the social media platform X.
“With this proposal, we are strengthening Finland’s defense and enabling the full use of NATO’s nuclear deterrent as protection for Finland,” Hakkanen wrote.
Experts believe the most practical outcome involves allied aircraft. Instead of storing weapons locally, the country would likely let allied nuclear-capable jets use its air bases during a major crisis.
The French connection
This legislative pivot comes amid wider anxieties across the continent. European leaders are increasingly worried about Russia’s military build-up and unsure about the future of American protection under Donald Trump.
According to Bloomberg, Helsinki is now weighing whether to join a defense plan proposed by French President Emmanuel Macron. The French initiative aims to spread its independent nuclear umbrella across Europe.
A final decision on the French partnership is expected this autumn. Other nearby countries are already moving in that direction.
In late May, Norway signed its own deal to shelter under the French deterrent. Sweden and Denmark are currently considering similar moves to secure their borders.
