Complementarity or Competition? Franco-British Cooperation and the European Horizon of French Defense Policy
What does future hold for the Franco-British defense partnership after Brexit?
France and the United Kingdom have, for long, enjoyed a close defense relationship, thanks in part to their analogous strategic cultures. The 2010 Lancaster House treaties built on this proximity to expand cooperation in the fields of nuclear weapons, force projection, interoperability and industrial integration. In spite of genuine progress in the first years following the treaties, the Franco-British strategic partnership has had to face two pitfalls: on the one hand, Brexit and its political consequences for the United Kingdom, and, on the other hand, President Macron’s attempt to revive European defense and Franco-German cooperation. The tenth anniversary of Lancaster House should offer the opportunity to rethink the convergence between bilateral cooperation and the resolutely European horizon of French defense policy.

Return to the East: the Russian Threat and the French Pivot to Europe's Eastern Flank
Russia’s full-scale invasion of Ukraine on February 24, 2022, has flung Europe’s Eastern flank into a new phase of strategic confrontation. It has had a major effect on France’s position, which was previously somewhat timid, leading it to significantly reinforce its deterrence and defense posture in support of the collective defense of Europe, in the name of strategic solidarity and the protection of its security interests.
Military Stockpiles: A Life-Insurance Policy in a High-Intensity Conflict?
The war in Ukraine is a reminder of the place of attrition from high-intensity conflict in European armies that have been cut to the bone after three decades of budget cuts. All European forces have had to reduce their stocks to the bare minimum. As a result, support to Ukraine has meant a significant drain on their operational capabilities. A significant amount of decommissioned systems were also donated, due to the lack of depth in operational fleets.
