Finland lifts nuclear weapons ban in landmark shift of country’s defence policy amid growing threats from Russia

Thursday, June 18, 2026 - Finland has approved new legislation allowing the import, transport, supply and possession of nuclear weapons on its territory, marking a major shift in the country’s defence policy amid growing security concerns over neighbouring Russia

The new law removes long-standing restrictions that had prohibited nuclear weapons from being brought into Finland. The previous ban was contained in the 1987 Nuclear Energy Act, which prevented any nuclear weapons from being stationed or transported on Finnish soil.

Finnish authorities said the legislative change was necessary due to what they described as an increasingly unpredictable security environment following Russia’s invasion of Ukraine and heightened military activity near Finland’s border.

Despite the legal change, the Finnish government stressed that it has no immediate plans to host nuclear weapons. Defence Minister Antti Häkkänen said the previous law had created complications for Finland after it joined NATO in April 2023.

According to Häkkänen, the old legislation was increasingly incompatible with Finland’s obligations as a NATO member, given that the alliance’s collective defence strategy includes nuclear deterrence. Under NATO’s framework, member states cooperate on defence matters, including nuclear planning and deterrence policies, even if they do not host nuclear weapons themselves.

The new legislation means Finland could theoretically host NATO nuclear assets in the future if circumstances required, bringing the alliance’s nuclear capabilities closer to Russia’s northwestern border. The move comes amid growing concern over Russian military activity near Finland. Recent satellite imagery reportedly shows construction underway at a new Russian military base close to the Finnish border.

Military analysts say the installation could accommodate between 4,000 and 6,000 personnel once completed. The base is located near Finland’s eastern frontier, which stretches approximately 830 miles and is now NATO’s longest direct border with Russia. Reports indicate that Russia has also expanded military infrastructure in Kamenka, around 35 miles from Finnish territory, where more than 100 installations capable of housing thousands of troops have been established.

Finnish officials have repeatedly warned about potential security threats stemming from Russia’s actions since the outbreak of the war in Ukraine. The country has already taken several defensive measures, including closing border crossings with Russia following allegations that Moscow was encouraging migrants to enter Finland illegally as part of a hybrid pressure campaign.

To strengthen border security, Finland has also constructed sections of a 10-foot-high border fence topped with barbed wire along parts of its frontier with Russia. The latest legislative change reflects Finland’s broader efforts to strengthen its security posture as tensions between NATO and Russia remain high and concerns continue to grow over military developments in the region.
