Finland on Monday became the tenth European state to join France’s Forward Deterrence framework (dissuasion avancée). President Alexander Stubb’s office and the Élysée issued a joint statement on the entry. President Emmanuel Macron launched the concept on March 2, 2026, at Île Longue, saying recent U.S. national security and defense strategies illustrate a “reordering of US priorities” and a strong incentive for Europe to address its own security more directly.

Stubb said the initiative strengthens European security, reinforces Europe’s responsibility for its own defense, and helps prevent escalation. He said it does not replace or overlap NATO nuclear deterrence and that Finland’s priority remains NATO and the European Union. Finland does not intend to station nuclear weapons on its territory in peacetime. Finland holds a land border with Russia of about 1,300 kilometers, the longest among NATO allies.

How Forward Deterrence Differs From NATO Nuclear Planning

Partners can pursue doctrine dialogue, joint exercises with Finnish observers or conventional roles, and, ultimately, temporary deployments of elements of France’s strategic air forces, including nuclear-capable assets. The French president alone decides on any use of French nuclear forces, and France stands outside NATO’s nuclear mission, in contrast to the Alliance’s shared Nuclear Planning Group. For Finland as a NATO member, a crisis would still run first through Alliance decision-making; Forward Deterrence adds consultation and presence options beside that track.

Partners, Nordic Steps, And Estonia’s Talks

Early partners included Germany, Poland, Greece, the Netherlands, Belgium, Denmark, and Sweden; Norway joined later; Finland is the tenth partner, bringing the arrangement to eleven countries including France. Defense Minister Antti Häkkänen called Finland’s entry a “natural step” following Norway, Sweden, and Denmark. He said the framework creates no NATO-style collective-defense obligations and that France is not asking partners to fund the deterrent.

Estonian Prime Minister Kristen Michal told AFP that Estonia is “in discussion” with France about joining. He said membership is not automatic, that it requires capabilities and readiness, and that Estonia is already under the NATO umbrella.

Helsinki Partnership And Forward Land Forces

The same day, Finnish Foreign Minister Elina Valtonen and French Foreign Minister Jean-Noël Barrot signed a strategic partnership document between Finland and France in Helsinki. France announced in July 2026 that it would contribute rotating ground forces to NATO’s Forward Land Forces in Finland, a presence stood up in June 2026 with Sweden as framework nation. A Nuclear Steering Group is to be established in the coming months to begin implementing the Forward Deterrence cooperation.
