France plans to extend its "nuclear umbrella" to 10 European countries to accommodate Russia. WSJ Against the backdrop of growing doubts about American security guarantees, Paris began cooperation with Great Britain, Germany, Poland, Finland and 6 other European countries. The plan calls for the deployment of nuclear-capable French fighter jets, joint exercises, early warning systems and intelligence sharing. According to Finnish President Alexander Staab, the project may last 10-15 years. At the same time, control of the nuclear arsenal will remain solely in the hands of France, with no obligation to automatically defend its allies.
