French nuclear weapons, 2025

France’s nuclear weapons arsenal has remained stable in recent years, but significant modernizations are underway of the country’s ballistic missiles, cruise missiles, submarines, aircraft, and nuclear industrial complex. We estimate that France currently has a nuclear weapons stockpile of approximately 290 warheads, as well as approximately 80 retired warheads awaiting dismantlement.

🆕 Planning for the Unthinkable: the targeting strategies of nuclear-armed states Intense secrecy around nuclear targeting means that most individuals—including lawmakers—do not have much understanding of how fateful decisions about what to target during wartime are made.

Planning for the Unthinkable: The targeting strategies of nuclear-armed states The quantitative and qualitative enhancements to global nuclear arsenals in the past decade—particularly China’s nuclear buildup, Russia’s nuclear saber-rattling, and NATO’s response—have recently reinvigorated debates about how nuclear-armed states intend to use their nuclear weapons, and against which targets, in what some describe as a new Cold War. Details about who, what, where, when, why, and how countries target with their nuclear weapons are some of states’ most closely held secrets. Targeting information rarely reaches the public, and discussions almost exclusively take place behind closed doors—either in the depths of military headquarters and command posts, or in the halls of defense contractors and think tanks. The general public is, to a significant extent, excluded from those discussions. This is largely because nuclear weapons create unique expectations and requirements about secrecy and privileged access that, at times, can seem borderline undemocratic. Revealing targeting information could open up a country’s nuclear policies and intentions to intense scrutiny by its adversaries, its allies, and—crucially—its citizens. This presents a significant democratic challenge for nuclear-armed countries and the international community. Despite the profound implications for national and international security, the intense secrecy means that most individuals—not only including the citizens of nuclear-armed countries and others that would bear the consequences of nuclear use, but also lawmakers in nuclear-armed and nuclear umbrella states that vote on nuclear weapons programs and policies—do not have much understanding of how countries make fateful decisions about what to target during wartime, and how. When lawmakers in nuclear-armed countries approve military spending bills that enhance or increase nuclear and conventional forces, they often do so with little knowledge of how those bills could have implications for nuclear targeting plans.

The American president has the sole authority to order a nuclear strike, even if every adviser in the room is against it.

My latest: @projectsyndicate.bsky.social asked me (and four other analysts) to offer our thoughts on whether US allies should begin thinking about building their own nuclear weapons. My answer: as bad as things look now, proliferation can make things worse. www.project-syndicate.org/magazine/tru...

A New Nuclear Calculus?

Thorsten Benner, et al consider whether America's friends and allies should pursue their own nuclear-weapons capabilities.
