When Johann Wadephul arrived in Athens, the message he carried was meant to reassure but instead exposed the fault lines running through Europe’s security architecture. His insistence that German supplied weapons to Turkey must never be used against Greece was framed as a “prerequisite”, yet the need to state it so explicitly underlined a deeper problem. Berlin is no longer balancing between two uneasy allies, it is navigating a widening strategic fracture shaped as much by transatlantic tensions as by Aegean rivalries.
Germany’s position is becoming increasingly difficult to sustain. For decades, Berlin has maintained a policy of equal distance between Athens and Ankara, both members of NATO and both central to Europe’s security calculus. That balancing act was always fragile, built on the assumption that disputes in the Aegean could be managed without forcing a choice. Today, that assumption is under strain. Greece expects solidarity as a member of the European Union, while Turkey remains indispensable to Germany as a strategic partner on migration, trade, and regional stability.
What has changed is the external environment. The growing rift between Berlin and United States is no longer abstract. It is shaping realities on the ground. Donald Trump has openly criticised Friedrich Merz and signalled a further drawdown of American troops from Germany, while simultaneously deepening rhetorical and strategic alignment with Athens. His praise for Kyriakos Mitsotakis and reports that Greece could benefit from a relocation of US forces during tensions with Iran have added a new dimension to an already complex equation. The Aegean is no longer just a regional dispute. It is becoming entangled in broader geopolitical realignments.
Against this backdrop, Wadephul’s visit appeared cautious, even evasive. In meetings with Giorgos Gerapetritis and Mitsotakis, the most sensitive issue, Turkey, was largely sidestepped in public. Yet it dominated the context. Greece and Turkey remain locked in a decades long rivalry over maritime boundaries, sovereignty claims, and military posture in the Aegean. The arms race between them is not theoretical, it is embedded in procurement decisions, patrol operations, and daily strategic calculations.
Recent incidents have sharpened Greek concerns about Germany’s role. Athens has formally protested to Berlin following two episodes involving German led or operated missions. In one case, a patrol under NATO’s Standing Maritime Group 2 used maps that omitted the names of Greek islands after Turkish objections, relying instead on coordinates. In another, a German coastguard vessel operating under Frontex reportedly followed instructions from the Turkish coastguard in waters Athens considers under its responsibility. For Greece, these are not minor procedural issues. They risk creating legal ambiguities in a region where sovereignty is already contested. The fear in Athens is that such precedents could gradually normalise “grey zones” in the Aegean.
Berlin’s silence on these incidents has only deepened mistrust. At the same time, Germany continues to pursue defence and industrial policies that cut both ways. Its support for Turkey’s inclusion in the EU’s €150 billion SAFE procurement programme was blocked by Greece, which insisted on conditions ensuring that third countries do not pose security threats to member states. The disagreement reflects a broader divergence in how the EU itself views Turkey, as a partner to be integrated or a rival to be contained.
The issue of arms exports sits at the centre of this tension. Germany’s decision to supply both Greece and Turkey with advanced Type 214 submarines has been particularly contentious. For Athens, the prospect of Ankara operating identical platforms undermines any sense of qualitative advantage. Greek officials have even explored the possibility of inserting clauses in future contracts to prevent such parity. Meanwhile, Thyssenkrupp Marine Systems has moved ahead with agreements to upgrade Greece’s existing submarines, while also positioning itself for potential new contracts, including the Type 212 CD. These industrial links are presented as signs of partnership, but they coexist uneasily with parallel cooperation with Turkey.
Greece, for its part, is no longer relying solely on Germany. Following the visit of Emmanuel Macron to Athens, discussions have intensified around a possible purchase of French Blacksword Barracuda submarines, a deal that could exceed €5 billion. This is not just a procurement decision. It is a signal that Athens is willing to diversify its defence partnerships if confidence in Berlin continues to erode.
Wadephul’s carefully worded assurance that German weapons should only be used against “external enemies” captures the dilemma but does not resolve it. In the Aegean, the line between external and internal threats is precisely what is disputed. Greece and Turkey are allies on paper, but adversaries in practice across multiple domains. Any arms transfer, regardless of intent, is inevitably interpreted through that lens.
What is unfolding is more than a bilateral disagreement. It is a test of Europe’s ability to act cohesively in a shifting geopolitical landscape. Germany’s traditional role as a stabiliser is being challenged by competing pressures, from within the EU, from its relationship with Turkey, and from an increasingly unpredictable United States. The risk is that in trying to maintain balance, Berlin ends up satisfying neither side.
For now, Germany continues to walk that line, emphasising partnership with Greece while preserving strategic ties with Turkey. But the margin for ambiguity is narrowing. As tensions in the Aegean intersect with broader global rivalries, neutrality becomes harder to sustain. Eventually, choices will have to be made, not in rhetoric, but in policy.
And in the current climate, even carefully chosen words are no longer enough to hold the balance together.
