Norway will begin talks with France on joining its nuclear umbrella, French President Emmanuel Macron and Norwegian Prime Minister Jonas Gahr Stoere announced on Wednesday, marking a significant shift in European defense cooperation.
The announcement came during a meeting in Paris, where the two leaders also signed a broader defense agreement that includes Norway joining a French-led nuclear weapons initiative.
The move reflects growing concern across Europe over long-term reliance on the United States for security and defense guarantees.

Shift Toward Closer European Defence Cooperation
Norway has traditionally relied heavily on NATO and the U.S. nuclear umbrella as part of its security strategy. However, the new agreement signals a move toward deeper defense coordination within Europe.
Stoere stressed that NATO and the United States would remain Norway’s primary deterrence framework, but described France’s nuclear capabilities as an important contribution to the alliance.
“France’s capabilities are an important contribution to NATO’s deterrence posture, which is important for us,” Stoere said.
Under the agreement, Norway would participate in what France describes as “forward nuclear deterrence,” allowing European partners to become more closely involved in French strategic thinking on nuclear defense.

Macron Pushes European Strategic Autonomy
Macron said the agreement established a principle of mutual assistance between France and Norway and would contribute to Europe’s ambitions for greater strategic autonomy.
“This agreement establishes a principle of mutual assistance between our two countries,” Macron said.
The initiative follows France’s proposal in March to extend the protection of its nuclear umbrella to other European nations. In practice, the policy means that an attack on a participating country could potentially trigger a French nuclear response.
Norway joins Poland and Lithuania as countries receiving French nuclear protection arrangements. Both nations also share borders with Russia.
Security Concerns Drive European Cooperation
The agreement comes as European countries seek to strengthen defense cooperation amid heightened tensions with Russia and uncertainty surrounding future U.S. commitments to European security.
Stoere said closer cooperation between European nations and transatlantic allies was necessary to strengthen overall security.
“This closer cooperation will make European and transatlantic security stronger,” he said, adding that Europe needed to increase defense spending and coordinate investments more effectively.
Norway, which has a population of 5.6 million, is a NATO member but not part of the European Union. The Nordic country shares an Arctic border with Russia.
Despite the new defense framework, Stoere clarified that nuclear weapons would not be stationed in Norway during peacetime.
The agreement instead focuses on strategic cooperation and deterrence planning rather than the physical deployment of nuclear arms on Norwegian territory.
