The TriArch Program (Trilateral Approach to the Transatlantic Security Architecture) brings together two complementary initiatives of the Forum de Défense et de Stratégie (FDS):

• An annual seminar on the transatlantic security architecture, now organized in a trilateral France–Canada–Germany format (first held in 2025, following several Franco-German editions), bringing together decision-makers, experts, academics, and young leaders for public panels and closed-door discussions.

• A trilingual podcast, currently in development, which will explore major transatlantic strategic issues in partnership with several organizations associated with the FDS.

​

The first trilateral edition of the seminar in 2025 marked a major evolution, introducing for the first time two filmed public sessions, thereby enhancing the dissemination and impact of the debates. The next edition is planned for autumn 2026, with the aim of extending and deepening this dynamic, potentially in Berlin or in Canada.

Why a trilateral France–Canada–Germany format?

This unique format responds to shared strategic and political considerations. For Canada, it offers the opportunity to move beyond a posture perceived as exclusively oriented toward the United States, to strengthen its diplomatic and strategic presence in Europe, and to work with two central powers of the EU and NATO to advance its positions, notably on the Arctic, collective defense, and industrial cooperation. For France and Germany, integrating a non-European transatlantic partner helps avoid the image of a dominating “duopoly” in Western Europe, gain legitimacy, and reduce bilateral tensions, while partnering with an ally that is both culturally and militarily close. Together, the three countries can form a core of reflection and action capable of putting forward common strategic orientations in the face of potential U.S. political instability, the war in Ukraine, hybrid threats, and the spread of hostile narratives, while strengthening the European — and non-American — pillar within the transatlantic security architecture.
