Overview
- Finland announced on Monday, Sept. 14, 2026, that it will join France’s Forward Deterrence initiative and will set up a bilateral nuclear steering group to negotiate implementation.
- The planned cooperation will focus on regular consultation, joint exercises, and the possibility of temporary deployments of French nuclear-capable aircraft to allied territory.
- France will retain exclusive authority over any use of its nuclear forces and will not transfer command or station nuclear weapons in Finland during peacetime.
- Finland removed a long-standing domestic ban on nuclear explosives in mid-2026 to clear the legal path for closer deterrence cooperation with France and other European partners.
- Officials say the initiative is meant to deepen European burden-sharing and strategic signaling in response to Russia’s aggression and questions about U.S. reassurance, and it could prompt closer continental planning and more visible air operations to deter escalation.
