The Imia/Kardak Dispute in the Aegean Sea

In January 1996, Greece and Turkey came dangerously close to open conflict over two small, uninhabited islets known as Imia (Greek) and Kardak (Turkish). Their lack of intrinsic value did not prevent a full-scale diplomatic and military escalation—largely driven by Ankara’s willingness to challenge an established status quo. As so often in Greek-Turkish relations, a minor issue was inflated into a major crisis, requiring U.S. intervention to prevent further deterioration.

Situated between the Greek island of Kalymnos and Turkey’s Bodrum peninsula, the islets became the latest flashpoint in a long-standing pattern: Greece relying on international law, and Turkey contesting it when the outcome proves inconvenient.

The Aegean Dispute
Modern tensions originate in the aftermath of the Greco-Turkish War and were formally addressed by the Treaty of Lausanne, which defined borders and obligations between the two states[1]. While Greece has largely adhered to this framework, Turkey has repeatedly sought to reinterpret or challenge aspects of it in pursuit of broader strategic aims.

The Aegean dispute centres primarily on territorial waters and continental shelf rights. Greece maintains a six nautical mile limit but, in line with the United Nations Convention on the Law of the Sea, retains the sovereign right to extend this to twelve nautical miles[2]. Turkey’s opposition, despite the convention reflecting widely accepted international norms, reveals the extent to which legal principles are subordinated to geopolitical concerns.

Athens has consistently emphasized that any extension would preserve freedom of navigation through the principle of "innocent passage". Nevertheless, Ankara continues to portray such a move as unacceptable, even describing it as a casus belli, which is an unusually aggressive stance in response to a lawful entitlement.

On the continental shelf, Greece argues that its islands are fully entitled to maritime zones under international law. Turkey’s preference for a median line that minimizes the effect of these islands reflects a selective reading of that same legal framework. The resulting deadlock has produced decades of tension, including Turkish exploratory activities in disputed areas and repeated but inconclusive recourse to international adjudication.

Militarization
The issue of militarization further illustrates the asymmetry in threat perception. While the Treaty of Lausanne and the Paris Peace Treaty imposed certain demilitarization obligations, Greece has argued—convincingly, in its view—that these must be understood in light of the inherent right to self-defence under the UN Charter.

Following Turkey’s 1974 intervention conquest and occupation of northern Cyprus, Greece faced a significantly altered security environment. The subsequent strengthening of Greek defences on Aegean islands was therefore less a provocation than a predictable response. Turkey’s parallel military buildup along its western coast has only reinforced Greek concerns, even as Ankara continues to frame the issue as Greek non-compliance.

Related Issues
Broader disputes over minority rights and Cyprus continue to poison bilateral relations. The Treaty of Lausanne attempted to resolve ethnic tensions through population exchanges, but lingering minority issues remain a source of mutual accusations—though Greece frequently points to Turkey’s record as the more problematic. Remember the massacre of Greeks in Smyrna (now Izmir) in 1922, when an estimated 150,000 were murdered by Turks. Remember also Turkey's version of the infamous Kristallnacht in 1955.

Cyprus, in particular, stands as a persistent reminder of the consequences of unilateral military action, further deepening Greek scepticism toward Turkish intentions in the region.

The Status of Imia/Kardak
From the Greek perspective, the legal status of Imia/Kardak is far less ambiguous than Turkey suggests. The dispute ultimately hinges on whether the islets form part of the Dodecanese. This is an issue that, based on existing treaties, appears largely settled.

Italy’s seizure of the Dodecanese in 1912 and its formal recognition in the Treaty of Lausanne included not only the main islands but also their "dependent islets". When Italy transferred the Dodecanese to Greece under the Paris Peace Treaty[3], these associated islets were understood to be included, even if not individually named, which is a common practice in treaty law.

Turkey’s argument based on geographic proximity is difficult to reconcile with Article 12 of the Lausanne Treaty, which clearly stipulates that only islands within three miles of the Turkish coast remain under Turkish sovereignty. Since Imia/Kardak lies beyond this limit, the legal implication favours Greece.

Moreover, the Italian-Turkish Agreement placed the islets on the Italian side of the boundary, reinforcing their later transfer to Greece[4]. Turkey’s dismissal of this agreement on procedural grounds appears, from the Greek viewpoint, less a legal objection than a convenient means of reopening a settled issue.

In this light, the Imia/Kardak crisis can be seen not as a genuine legal dispute, but as part of a broader pattern in which Turkey challenges established arrangements to create leverage—turning even the smallest and most inconsequential territories into instruments of geopolitical pressure.
