Norway has become the ninth European country to join France’s nuclear deterrence initiative, marking another step in Europe’s efforts to strengthen its security architecture amid Russia’s continued military buildup and growing uncertainty over long-term U.S. commitments to the continent’s defense.
The announcement came during Norwegian Prime Minister Jonas Gahr Støre’s visit to Paris, where he met French President Emmanuel Macron and signed a broad defense and security agreement with France.
The move adds Norway to a growing group of European nations participating in discussions on what France describes as “forward nuclear deterrence,” a framework aimed at extending the strategic effect of France’s nuclear arsenal to bolster European security while maintaining full French control over nuclear decision-making.
Standing alongside Macron in Paris, Støre confirmed Norway’s participation in the initiative. “Along with nine other European countries, Norway will participate in your initiative on how French nuclear weapons can contribute to security and deterrence in Europe,” the Norwegian prime minister said.
Støre emphasized that Norway’s security would continue to rely primarily on NATO despite joining the French-led discussions. “Our deterrence will continue to be provided by NATO,” he said.
He also highlighted Norway’s strategic position near Russia, noting that “Russia’s largest nuclear arsenal is located in the High North, just a few kilometers from Norway.”
Norwegian officials stressed that no nuclear weapons would be stationed in the country during peacetime.
He told Norwegian news agency NTB earlier the same day: “We are doing this in light of the security policy situation in Europe, including Russia’s massive rearmament, also in the nuclear domain, and that it is waging a full-scale war against another European country.”
Macron’s Vision for European Nuclear Deterrence
The initiative stems from a proposal unveiled by Macron in March, when he announced plans for France, the European Union’s only nuclear-armed state, to play a larger role in continental security through its nuclear capabilities.
Under the proposed framework, participating countries could engage in nuclear-related consultations, information sharing, joint exercises and potentially host temporary deployments of French nuclear-capable military assets.
At the time, Macron said countries joining the program would be able to temporarily host French “strategic air forces,” which could “spread out across the European continent” to “complicate the calculations of our adversaries.”
France has made clear, however, that it will retain sole authority over its nuclear arsenal. Unlike NATO’s existing nuclear-sharing arrangements, the French model does not envision partner nations having a direct operational role in the use of nuclear weapons.
French officials have described the doctrine as intentionally “strategically ambiguous,” allowing Paris flexibility in determining how and when its nuclear deterrent could be employed in response to threats affecting European allies.
Before Norway joined, eight countries had already signed up for discussions with Paris: Belgium, Denmark, Germany, Greece, the Netherlands, Poland, Sweden and the United Kingdom.
Some countries have progressed further than others in defining the scope of cooperation.
Germany and France established a steering group earlier in 2026 to develop the framework, with initial concrete measures expected by the end of the year. German officials are also expected to observe French nuclear exercises beginning in September and gain access to French nuclear infrastructure for educational and planning purposes.
Poland has explored the possibility of hosting French nuclear-capable Rafale fighter jets under future arrangements, while discussions continue among other participating nations regarding the practical implementation of the initiative.
Europe Responds to Shifting Security Dynamics
The expansion of France’s deterrence initiative reflects broader changes in Europe’s security outlook following Russia’s invasion of Ukraine and growing concerns about the future reliability of U.S. security guarantees.
European governments have accelerated defense spending and military cooperation while exploring ways to assume greater responsibility for the continent’s defense.
The debate has also been shaped by repeated calls from U.S. President Donald Trump for European allies to shoulder a larger share of NATO’s defense burden.
“If they don’t pay, I’m not going to defend them,” Trump said in 2025 when discussing NATO allies that fail to meet defense spending commitments.
At NATO’s summit in The Hague earlier in 2026, alliance members agreed to a new target of spending 5% of GDP on defense and defense-related investments by 2035, significantly higher than the alliance’s longstanding 2% benchmark.
France and Norway Sign Broader Defense Pact
Alongside the nuclear deterrence discussions, France and Norway signed a comprehensive bilateral defense and security agreement known as the Narvik Agreement.
According to Macron, the pact includes a mutual assistance clause, enhanced military dialogue and cooperation in areas including air defense, Arctic security, space and cybersecurity.
Macron described Norway as “a key geographical and strategic partner with which we already had significant cooperation in ensuring the protection of Allied territory against external threats.”
He added: “Norway, a key geographical and strategic partner with which we already had significant cooperation in ensuring the protection of Allied territory against external threats, will represent a strong added value for this enhanced deterrence.”
Støre said the agreement would deepen military cooperation between the two countries.
“The agreement reinforces our cooperation through concrete structures, plans, exercises and prepositioning of equipment, and will enable us to mount a swift and coordinated response when it is really needed,” he said.
“The agreement also provides a framework for closer cooperation on hybrid warfare, maritime security, space cooperation, cybersecurity, support to Ukraine and defence industrial cooperation.”
France currently possesses approximately 290 nuclear warheads, making it the world’s fourth-largest nuclear power after Russia, the United States and China, and ahead of the United Kingdom.
