Raoul Castex: an admiral strategist at the heart of the spirit of defence
To mark the 90e As the IHEDN celebrates its 400th anniversary and the French Navy celebrates its 400th anniversary, we look back at the life of Admiral Raoul Castex (1878-1968), founder of the Institute.

Franco-British defence cooperation
This fact sheet focuses on Franco-British military cooperation, from its historical foundations marked by the Entente Cordiale of 1904, the First World War, the Battle of Dunkirk (1940) and the Suez Crisis (1956) to post-Cold War operational rapprochement. It analyses the role of the Treaties of Lancaster House (2010) and Lancaster 2.0 (2025), which institutionalise the Franco-British Joint Expeditionary Force (CJEF) and strengthen nuclear and capability coordination, while highlighting the limits of this solidarity in the face of national trade-offs and divergent industrial choices. Finally, it sheds light on the prospects for the relationship, between opportunities for European rapprochement post-Brexit and the challenges posed by competition in the development of military capabilities. It also sheds light on the differing approaches of Paris and London to Ukraine, in a context of strategic recomposition of European defence.
