At the Munich Security Conference on February 13, 2026, German Chancellor Friedrich Merz confirmed that Berlin has "begun confidential talks with the French President on European nuclear deterrence." The statement, delivered against the backdrop of deepening anxiety about American reliability, marks the first formal German engagement with an offer Paris has extended since 2020. What was once dismissed as a French aspiration for grandeur has become a serious topic of strategic discussion, propelled by a fundamental question: can Europe still depend on Washington's nuclear umbrella?
The significance lies not in the novelty of the French proposal, but in Germany's willingness to entertain it. For decades, Bonn and then Berlin anchored European security in the transatlantic framework, viewing NATO's integrated command and American extended deterrence as irreplaceable. That Merz—a Christian Democrat from the traditionally Atlanticist wing of German politics—is now exploring alternatives signals how profoundly the ground has shifted. The move reflects a broader European calculation that strategic autonomy is no longer an aspiration but a necessity.
The American reliability crisis
The proximate cause of this recalibration is the Trump administration's systematic erosion of alliance credibility. During the 2024 campaign, then-candidate Trump publicly encouraged Russia to "do whatever the hell they want" to NATO allies he deemed delinquent on defense spending. That rhetoric has been matched by policy: Vice President JD Vance used the previous Munich conference to issue barely-veiled ultimatums to European capitals, while the administration has questioned the automatic nature of Article 5 commitments. Polling conducted across EU member states in early 2026 showed trust in American security guarantees at its lowest point since such surveys began in the 1950s.
This is not merely a diplomatic spat. European defense planners are confronting scenarios that were theoretical until recently: a major Russian offensive in the Baltics with Washington's response uncertain, or a presidential decision to withdraw from NATO altogether. The legal architecture of the alliance may remain intact, but the political will underpinning extended deterrence—the promise that the United States would risk New York to defend Tallinn—is openly questioned. Merz's initiative is an acknowledgment that Europe must prepare for a world in which that promise cannot be relied upon.
President Emmanuel Macron has been proposing a "strategic dialogue" on the "European dimension" of France's nuclear forces since his Élysée speech in February 2020. At the time, the offer was met with polite disinterest from Berlin and outright skepticism from eastern European capitals, who saw it as a French attempt to substitute Parisian leadership for American protection. What has changed is not Macron's vision, but the context. Germany's formal engagement transforms the proposal from a unilateral French overture into a potential bilateral framework with Europe's largest economy and most populous state.

Uncharted institutional territory
Beyond the doctrinal hurdles lie political and legal minefields. Germany is prohibited from possessing nuclear weapons under both the Treaty on the Non-Proliferation of Nuclear Weapons and the 1990 Treaty on the Final Settlement with Respect to Germany. While financing French capabilities or hosting French assets might technically differ from possession, such arrangements would test the boundaries of these commitments and invite challenges from Moscow, which has already framed European defense initiatives as violations of post-Cold War agreements. Eastern European allies, meanwhile, remain skeptical that any European arrangement could replace the credibility of American power, particularly given the absence of a unified EU foreign policy or a common threat assessment.
The transfer of NATO commands to European officers and the broader unraveling of arms control frameworks create a context in which traditional institutional anchors are weakening. Merz's initiative must be understood within this broader pattern: Europe is being forced to improvise security arrangements in the absence of reliable American commitment, even as the strategic challenges from Russia intensify.
Whether this Franco-German dialogue produces a genuine European deterrent or remains a high-stakes political signal depends on choices that have not yet been made. What is certain is that the conversation itself marks a departure. The post-1945 European security order was built on the premise that the continent's defense was inseparable from American power. That premise is now under negotiation, and the alternative architectures being considered carry risks and complexities that Europe has never fully confronted. The talks Merz announced are confidential, but their implications are anything but private—they concern the most fundamental questions of sovereignty, security, and survival in an era where old certainties no longer hold.
