Introduction

On May 14, 2025, French President Emmanuel Macron signaled a historic shift in France’s nuclear posture by expressing willingness to deploy French nuclear weapons in other European nations. This statement comes amid rising geopolitical tensions, especially from the Russia-Ukraine conflict.

What is Nuclear Sharing?

Nuclear sharing is a defence arrangement where a nuclear-armed country places nuclear weapons in non-nuclear allied nations. This concept is not new—the United States has followed it for decades under NATO, stationing B61 tactical nuclear bombs in Germany, Belgium, Netherlands, Italy, and Turkey. The goal is to promote alliance unity and collective deterrence.

France’s Nuclear Capability

France is one of the recognized nuclear powers with approximately 290 nuclear warheads. These are delivered through:

  • Submarine-Launched Ballistic Missiles (SLBMs)
  • Air-Launched Cruise Missiles via Rafale fighter jets

If France begins deploying its arsenal abroad, it might need to expand its warhead stockpile to maintain credible deterrence.

Strategic Implications

  • Supporters argue it would boost Europe’s defence independence and strengthen deterrence against Russia.
  • Critics warn it might provoke Russia, which already sees NATO expansion as a direct threat.
  • This approach fits into France’s idea of “European Strategic Autonomy“—the belief that Europe should defend itself without depending heavily on the U.S..

Legal Angle: What Does the Law Say?

The Nuclear Non-Proliferation Treaty (NPT) of 1968 bans the transfer of nuclear weapons by nuclear states. NATO argues its sharing policy is legal, as the U.S. retains full control over its nukes. However, this logic is contested. France’s proposal could invite international scrutiny and legal debate.

A Shift in French Nuclear Policy

Historically, France has been fiercely independent in its nuclear doctrine. It kept its nuclear forces outside NATO command even during the Cold War. Macron’s move indicates a dramatic evolution in France’s security outlook—possibly the biggest since Charles de Gaulle established the independent “Force de Frappe” in the 1960s.
