France’s Big Bet on Nuclear Forward Deterrence

France has clear and compelling reasons to invite allied NATO nations into its nuclear decision-making process, although challenges remain.

President Emmanuel Macron’s announcement of French “dissuasion avancée” (forward deterrence) on March 2 is significant in its context, rather than in its essence alone. France has long held that Europe falls within its vital interests, and the strategic logic of a second nuclear decision center within the alliance has been implicit since the Cold War. What is new is the context: a United States visibly pressing Europeans to assume more responsibility for their own defense, and a continental military build-up of historic proportions that France intends to anchor around its nuclear posture—including, critically, the integration of European conventional forces into French nuclear operations. Against that backdrop, Macron’s offer of an increased arsenal, bilateral nuclear steering committees, joint exercises with eight named partners, and the conditional forward deployment of nuclear-capable Rafale aircraft has acquired strategic weight that earlier French proposals lacked.

The design of Macron’s initiative reflects a careful balancing act. France does not wish to appear as if it is replacing the United States as the continent’s security guarantor; doing so would fracture NATO and unsettle Washington. Nor can it reproduce the vagueness of past offers, which convinced no one, while respecting the nonproliferation concerns of some partners. The result is a framework that draws Germany, the United Kingdom, Poland, the Netherlands, Belgium, Greece, Sweden, and Denmark into French nuclear exercises and consultation structures, while still keeping sole launch authority in Paris. Partners neither receive French warheads nor share decision-making; the French nuclear force will not be deployed beyond French territory; and the existing nuclear planning and launch authority will not be altered. 

The initiative possibly carries two sets of objectives. Strategically, it aims to improve European deterrence and reduce dependence on the United States—either through credible French nuclear use in extremis, or more likely by compelling the US to intervene conventionally to prevent that eventuality. Economically, it could anchor the French defense industry at the center of Europe’s defense build-up, making partners institutionally and operationally dependent on French platforms in ways that protects its market share from Germany’s rising defense industry. Structurally this is stabilizing for both France and assuring for Europe. The more France’s defense industry prospers through investment and job creation, the more bipartisan support it will receive within France’s contentious domestic political scene. That economic logic broadens domestic political support for the initiative across the spectrum, adding the stability and predictability in the eyes of future partners that purely strategic arguments cannot guarantee. 

Deterrence in Peacetime and Wartime

In peacetime, the forward deterrence initiative performs a clear function. Operation Poker, France’s quarterly large-scale nuclear strike rehearsal, now incorporates allied conventional assets in escort, tanking, and electronic warfare roles. This builds allied familiarity with French nuclear operations and signals resolve to adversaries. The geographic coverage of France’s partners, from Denmark in the north to Greece in the south, create an “archipelago of forces” that is dispersed, survivable, and politically visible to the adversaries.

In a crisis, temporary basing of nuclear-capable Dassault Rafale aircraft on allied territory compresses the geographic and temporal........
