Estonia Opens Talks With France on Deeper Nuclear Deterrence Cooperation

Estonia has opened discussions with France over potentially deepening cooperation on nuclear deterrence, as European countries reassess the continent’s long-term security architecture and the role of France’s nuclear arsenal.

Prime Minister Kristen Michal confirmed the talks while attending the European Arctic Summit in Rovaniemi, Finland, saying Estonia was in discussions with Paris over possible participation in France’s enhanced nuclear deterrence initiative.

Michal cautioned, however, that participation is not automatic and would require specific capabilities and military readiness.

Estonia is already protected by NATO’s nuclear deterrence framework, while France also maintains troops in the country as part of NATO’s forward presence in the Baltic region. Michal said that if cooperation with France could be deepened in the nuclear field, Estonia was prepared to explore the possibility.

The comments come immediately after Finland formally joined France’s Forward Nuclear Deterrence Initiative, becoming the tenth European country participating in the framework.

Finland’s move represents a significant expansion of the French initiative because the country shares a more than 1,300-kilometer border with Russia and only joined NATO in 2023.

The French initiative is designed to deepen European cooperation around nuclear deterrence through political consultations, military exercises and potentially temporary deployments of French nuclear-capable aircraft to participating countries.

France would retain exclusive control over its nuclear arsenal, and any decision on the use of French nuclear weapons would remain with the French president.

The United Kingdom, Germany, Poland, Sweden, the Netherlands, Belgium, Greece, Denmark and Norway have already participated in the initiative, according to information released around Finland’s accession.

Finland has stressed that participation does not replace NATO’s nuclear deterrence framework. President Alexander Stubb said NATO and the European Union remain Helsinki’s primary security structures and that Finland does not intend to permanently station nuclear weapons on its territory during peacetime.

Estonia has taken a similarly cautious approach.

Michal emphasized that Tallinn remains covered by NATO’s nuclear umbrella and already maintains extensive defense cooperation with France. French forces have been deployed in Estonia since 2017 as part of NATO’s enhanced forward presence.

The discussions nevertheless underline a broader shift in European defense policy.

France has increasingly promoted its independent nuclear arsenal as a potential additional pillar of European deterrence, while European governments debate how much responsibility they may eventually need to assume for their own strategic defense.

For Estonia, which shares a border with Russia and has consistently advocated stronger NATO deterrence in northeastern Europe, participation in a French-led framework could provide an additional layer of strategic cooperation without replacing existing NATO commitments.

No final decision on Estonia’s participation has yet been announced.
