Germany is currently re-evaluating its nuclear deterrence policy amid changing political dynamics and heightened global security concerns.

Recent developments indicate an evolving stance regarding nuclear deterrence discussions, particularly in collaboration with France and the United Kingdom.

French President Emmanuel Macron has actively invited Germany to engage in talks about European nuclear defense, underscoring the importance of France's nuclear capabilities within the context of European security.

Historically, Germany has relied on U.S. nuclear protection, with approximately 20 American nuclear weapons stationed at the Büchel airbase in Rhineland-Palatinate.

In accordance with NATO's nuclear-sharing doctrine, while the United States retains control over the release codes for these weapons, it is the German Bundeswehr that operates the aircraft capable of delivering them if necessary.

The foundation of Germany's nuclear policy is rooted in the 1990 Two Plus Four Treaty, which prohibits the country from developing its own nuclear arsenal.

However, public opinion regarding nuclear armament appears to be shifting.

Polls conducted in early March indicate that between 31% to 38% of Germans support the idea of pursuing an independent nuclear arsenal, marking a slight increase from previous years.

Despite this growing sentiment, significant hurdles remain.

Reports highlight that Germany lacks sufficient access to uranium for developing a domestic nuclear arsenal, primarily due to the constraints imposed by its nuclear non-proliferation commitments.

Additionally, Friedrich Merz, the leader of the Christian Democratic Union (CDU), has publicly reiterated that Germany should neither seek to possess nuclear weapons nor abandon its longstanding renunciation of nuclear arms.

Merz advocates for enhanced discussions surrounding European nuclear deterrence, particularly regarding collaborative security measures with France and the UK.

France maintains an arsenal of approximately 290 nuclear warheads, deployable from submarines and aircraft, which it asserts serves as a deterrent against potential aggressors.

While both the UK and France operate under NATO, their nuclear strategies diverge.

British nuclear systems closely align with U.S. strategies, while France emphasizes maintaining autonomous control over its nuclear forces.

The ongoing dialogue regarding the effectiveness of U.S. nuclear guarantees has led to increased skepticism among security analysts, particularly regarding the long-term viability of these assurances amid shifting political dynamics in Washington.

In response to these evolving security concerns, Germany is expediting its rearmament initiatives, with a realignment of national security policy taking place.

Potential collaborative military efforts between Germany and France could encompass joint exercises, although the establishment of French nuclear infrastructure within Germany remains unlikely.

Similarly, the UK's nuclear capability is primarily based on submarines and is heavily focused on national defense.

Experts in security suggest that the formation of a robust strategic alliance among European nations could enhance collective defense strategies.

However, the integration of French and British nuclear capabilities into a cohesive European defense framework presents substantial challenges.

Discussions are ongoing about the necessity for Europe to establish independent defense structures, particularly should reliance on U.S. deterrence begin to diminish.

These deliberations unfold against a backdrop of increasingly complex international relations and a transforming geopolitical landscape in Europe.
