Britain and France have taken a new step in strengthening defence cooperation by conducting joint exercises related to nuclear deterrence for the first time. As part of this event, RAF Typhoon fighters of the British Royal Air Force joined French Rafale fighter jets, participating in French nuclear exercises. This event marked a historic moment in bilateral relations between Europe's two nuclear powers. Britain and France are the only countries in the European Union and Europe as a whole that possess their own nuclear weapons, which gives their military cooperation in this sphere particular strategic significance. The participation of British fighters in French nuclear deterrence exercises demonstrates a deepening of the defence partnership between London and Paris against the backdrop of changing geopolitical conditions in Europe. Such joint exercises allow the two countries to practise the interaction of their armed forces and demonstrate unity on matters of defence and strategic deterrence. Although the details of the exercises are not fully disclosed for security reasons, the very fact of conducting such an event is viewed as a significant step towards closer integration of the defence capabilities of the two countries. This cooperation fits into the broader context of strengthening European defence capacity and coordinating action among NATO allies.
