Norway is set to open talks with France about joining France’s nuclear deterrence “umbrella,” French President Emmanuel Macron and Norwegian Prime Minister Jonas Gahr Støre said on Wednesday. The announcement is framed by both leaders as part of a broader reassessment of European security, amid concerns about how reliably the United States will back the region’s defence. Norway is described across outlets as having been a long-standing “Atlanticist,” placing heavy emphasis on NATO and the US, including the US nuclear deterrent. The proposed move would represent a shift toward closer defence cooperation within Europe, including deeper coordination with a European partner on deterrence. Details of how the arrangement would work, such as timing or the scope of integration, were not specified in the reports provided. The leaders communicated their plan following discussions in Paris, where Macron and Støre also discussed wider cooperation. The steps signal a change in how Norway views deterrence and risk-sharing as European governments consider contingency planning linked to US policy.
