In a significant address from the Île Longue nuclear submarine base in Brittany, French President Emmanuel Macron declared that France will increase its nuclear arsenal for the first time in decades and intensify weapons cooperation with eight European allies, including the UK. This move forms part of a "major" strengthening of France's deterrence doctrine amid growing concerns over US defence commitments.
Strengthening Deterrence Amid Geopolitical Upheaval
Macron emphasised that a "period of geopolitical upheaval, fraught with risk" necessitates this upgrade, with France being the EU's sole nuclear power. He stated that the increase is "essential" to maintain assured destructive power against multiple threats, though he did not specify the number of warheads to be added. France currently holds an estimated 290 nuclear warheads, the world's fourth-largest arsenal after Russia, the US, and China.
The French president insisted that this expansion is "not an arms race," but rather a strategic measure to ensure adversaries cannot contemplate attacking France without facing irreversible damage. He cited Russia's ongoing war in Ukraine, China's military expansion, and shifts in US defence strategy as key reasons for Europe to take greater responsibility for its security.
Enhanced European Cooperation and Deployment Plans
Macron announced the "gradual implementation of what I would call 'advance deterrence'," which includes considering France's deterrence strategy across the European continent while respecting sovereignty. He revealed that Paris could deploy nuclear-capable Rafale fighter jets to partner nations such as Germany and Poland, though decision-making on nuclear use remains solely with the French president.
Talks on enhanced cooperation have already begun with the UK, Germany, Poland, the Netherlands, Belgium, Greece, Sweden, and Denmark. This new model aims to "spread across the European continent" to complicate adversaries' calculations and may involve "the conventional participation of allied forces in our nuclear activities."
Reactions from European Leaders and Experts
Bruno Tertrais, deputy director of France's FRS thinktank, described Macron's speech as "the most significant update to French nuclear deterrence policy in 30 years" and a "major step forward." European leaders have responded positively, with Poland's Prime Minister Donald Tusk stating he is in talks with Paris and allies, adding, "We are arming up together with our friends so that our enemies will never dare to attack us."
Sweden's Prime Minister Ulf Kristersson confirmed participation in discussions, noting that strengthening Europe's defence capability is crucial since World War II, and these talks will involve dialogue with the US and NATO. Germany and France issued a joint statement establishing a "high-ranking nuclear steering group" to complement NATO's deterrence, with plans for German conventional participation in French nuclear exercises and joint strategic site visits.
Background and Broader Implications
Macron's speech, maintained despite escalating Middle East conflicts, underscores France's commitment to independence and power in facing global threats. This follows earlier discussions, including at the Munich Security Conference, where Macron called for a "re-articulation" of European security cooperation. The move also aligns with a July joint declaration between France and the UK on nuclear force coordination.
Amid Donald Trump's rapprochement with Russia and tougher stance on transatlantic alliances, European governments are increasingly reliant on intra-European defence initiatives. Macron's announcement marks a pivotal shift towards greater European autonomy in nuclear deterrence, reflecting broader geopolitical realignments and the urgent need for cohesive security strategies in a volatile world.
