French President Emmanuel Macron announced that Norway has officially joined the Paris-led "Advanced Nuclear Deterrence" project, following a bilateral summit hosted by Norwegian Prime Minister Jonas Gar Storre at the Elysee Palace.
The landmark move confirms that the continent has entered a whole new phase of thinking about its collective nuclear security, amid mounting regional doubts about the viability of the traditional U.S. security umbrella that has protected the continent since the end of World War II.
Expanding the French protection network
Under this declaration, Norway became the latest country to receive "coordinated French nuclear protection", following in the footsteps of Poland and Lithuania, which also share a direct border with Russia.
With the accession of Oslo, the number of countries under the umbrella of this program has increased to nine: Poland, Belgium, Denmark, Germany, Greece, the Netherlands, Sweden, and the United Kingdom (the continent's other nuclear power), expanding the project beyond the boundaries of traditional EU institutions towards the formulation of an inclusive European security space.
The New Nuclear Doctrine of Paris
French President Emmanuel Macron outlined the agreement, saying it "establishes the principle of mutual assistance between countries and supports Europe's ambitions to achieve greater strategic autonomy."
In March 2026, Macron unveiled from the Île Long nuclear base in Brittany, the biggest modification of the French nuclear doctrine in decades by increasing the size of the arsenal (290 nuclear warheads distributed among submarines and Rafale jets) for the first time since 1992, with Paris keen to keep the "nuclear button" French and exclusive without sharing the decision to use it with allies.
Norway's position and Russia's border
Norwegian Prime Minister Jonas Gaar Storre explained in remarks to the Norwegian news agency NTB that the agreement does not include the deployment of any nuclear weapons on Norwegian territory during times of peace, but rather strengthens cooperation through concrete structures and plans, advance deployment of equipment, as well as countering hybrid warfare, cyber and space security, and support for Ukraine.
The shift is a delicate step given that the Scandinavian country (5.6 million people) is a member of NATO, not the European Union, and shares a northern border with Russia, which is one of the hottest contact lines in the Arctic.
Redistributing the Atlantic Burden
Norwegian Prime Minister Storre stressed that his country's basic deterrence will remain based on NATO and the United States, adding that French capabilities represent "an important contribution to the alliance's deterrence system."
"Together we are working to redistribute the burden, and long before Trump came in it became imperative for Europe to pay more and make wiser investments and a more coordinated image," Storre added, referring to the changing geopolitical context since the outbreak of the Ukraine war and the return of Donald Trump with his hardline rhetoric calling on Europeans to pay the price for their security.
De Gaulle's legacy and the complexities of the future
French strategic memory has relinked this doctrine to the concept of "nuclear independence" that General Charles de Gaulle built on refusing to submit to the American umbrella, with Paris presenting itself today as the "sole nuclear guarantor" within the post-Brexit bloc.
Despite official assurances that the project complements NATO and does not compete with it, observers confirmed that there are complications and fears among some European countries that strengthening the French role will further provoke Moscow, or gradually transform the continent into a multi-center nuclear space, at a time when Europeans are now openly talking about joint militaries and defense industries independent of the U.S. decision.
