France Expands Nuclear Deterrence Strategy to Include European Allies

In a significant shift in its nuclear defense policy, France has announced plans to enhance its nuclear arsenal and extend its deterrence capabilities to cover other European nations. President Emmanuel Macron outlined these changes during a speech in Brittany, emphasizing the need for a robust nuclear strategy in response to an increasingly unstable global environment. He stated that the coming decades would be marked by the prominence of nuclear weapons.

Addressing naval officers at the Ile Longue base near Brest, Macron revealed that France would increase its nuclear warheads from the current count of approximately 300. He also announced the future launch of a new nuclear-armed submarine, named The Invincible, set for 2036. Furthermore, eight European countries, including the UK, Germany, Poland, and others, have agreed to participate in a new "advanced deterrence" strategy.

Polish Prime Minister Donald Tusk expressed support for the initiative, highlighting the collective effort to deter potential aggressors. Macron explained that these European allies could engage in exercises involving France's air-launched nuclear capabilities, known as the "force de frappe," and host air bases for French nuclear bombers. This strategic dispersion aims to complicate adversaries' calculations.

Under the new doctrine, partner countries will also collaborate on developing auxiliary capacities such as space-based alarm systems, air defense against drones and missiles, and long-range missile capabilities. Despite these changes, the core principle of France's nuclear strategy, as defined by former President Charles de Gaulle, remains intact. The French president will retain sole authority over nuclear launch decisions, and no explicit guarantees will be given to partner nations.

Macron's announcement marks the most significant evolution in French strategic thinking since 1960. The concept of "vital interests," previously vague, is now more defined, potentially encompassing European interests. However, in line with deterrence theory, specifics remain undisclosed. Additionally, France will no longer publicly disclose its nuclear warhead count.

France's cooperation with the United Kingdom, Europe's other nuclear power, continues to deepen. Recently, UK officials participated in exercises with France's Strategic Air Forces (FAS) for the first time. Following Macron's speech, France and Germany announced plans for closer collaboration in nuclear deterrence, including German participation in French nuclear exercises and the development of conventional capacities with European partners. This cooperation is intended to complement, not replace, NATO's nuclear deterrent capabilities.
