Paris and Berlin Align Rules for Long-Range Missile Strikes: France Fears Nuclear Response from Moscow

France is holding confidential consultations with German officials to align Berlin's approach to deep precision strike (DPS) weapons with French nuclear strategy, the Financial Times reports, citing six sources familiar with the negotiations. According to the publication, Paris aims to establish a unified approach regarding the circumstances under which European states can use long-range weapons and how Moscow might interpret such actions. The talks come against the background of active expansion of long-range arsenals in Europe and growing concerns over conflict escalation.

Risk of Nuclear Escalation: French Officials' Warning

One French official familiar with the discussion warned that even a conventional weapons strike on a Russian target could trigger a nuclear response. According to the official, if Moscow misinterprets the signal, the situation could rapidly escalate to the level of nuclear war, with both sides potentially failing to realize the danger in time. According to the FT, this exact scenario is the primary concern for Paris and dictates the tone of negotiations with Berlin.

European Rearmament and German Missiles

Paris's apprehensions stem from the fact that Germany and several other European countries—including the UK, Poland, the Nordic and Baltic states—are actively expanding their long-range missile arsenals to strengthen the continent's defense capabilities and deter Russia. In particular, Berlin is procuring and developing ground-launched missiles with a range of 500 to 2,000 km, enabling German armed forces to strike targets deep inside Russian territory. According to the FT, Germany has earmarked €780 billion for defense needs over a five-year period through the end of 2030.

«Forward Deterrence» and Its Unintended Consequences

Discussion surrounding France's nuclear strategy intensified after President Emmanuel Macron proposed in March 2026 discussing how the French nuclear deterrent could protect other European countries. The concept of «forward deterrence» involves engaging allies in French nuclear exercises, intelligence sharing, and action coordination in the event of a crisis. Germany, among others, has joined this initiative. However, French officials fear this concept could carry unintended consequences: if German or other European partners strike Russia, Moscow might hold Paris responsible as well.

«Nuclear Grammar»: Experience Partners Lack

France emphasizes that a nuclear-armed state possesses its own system of principles and unwritten rules for employing such weapons. One official termed this «nuclear grammar and vocabulary», which has been shaped over years. According to the official, Germany lacks this experience, making the alignment of approaches a particularly complex and vital task. Paris deems it necessary to formulate a clear, preferably public doctrine to help prevent Russia from misinterpreting European actions.

Coordination Mechanisms: Exercises and Working Group

Practical coordination work is already underway. In July 2026, Berlin officially agreed to participate in exercises involving French strategic forces. Furthermore, the two countries have established a special nuclear coordination group. Overall, France is gradually expanding cooperation with European states in nuclear deterrence amid Russian aggression and concerns over weakening US security guarantees. Current consultations with Berlin are essentially a logical continuation of this process, translated into concrete long-range weapons deployment scenarios.
