Overview
- Finland formally agreed to join France’s forward nuclear deterrence project on September 14, 2026, becoming the tenth European partner in the framework.
- President Alexander Stubb and Defence Minister Antti Hakkanen immediately clarified that Finland will not host nuclear weapons on its territory in peacetime.
- Finnish officials said participation is voluntary and does not create NATO‑style collective‑defense obligations for signatories.
- France will retain control of its arsenal and will not require partners to share maintenance costs, and officials said cooperation will include a joint steering group, dialogue, exercises and possible temporary deployments of French strategic aircraft for deterrence operations.
- The move builds on Finland’s post‑2022 security shift, including the June 2026 repeal of its Cold War nuclear ban and its NATO membership, and it could deepen Finnish ties with France while signaling a stronger European nuclear posture next to Russia.
