Under the leadership of President Recep Tayyip Erdogan, the Republic of Turkey has increasingly pursued a revisionist, ideologically driven foreign policy often described as Neo-Ottomanism. This strategic orientation seeks to re-establish Turkish influence across former Ottoman territories, particularly in the Eastern Mediterranean, the Levant, and North Africa. By blending nationalist ambitions with political Islamism, Ankara has actively challenged the regional status quo, seeking to position itself as a dominant hegemon. This expansionist posture has directly threatened the sovereign rights and security of democratic neighbors, leading to a natural alignment of interests between Israel, Greece, and Cyprus. These three nations have formed a robust trilateral partnership to defend their maritime borders, secure energy resources, and counter regional destabilization.
Historical Roots of Turkey's Maritime Ambitions
The roots of Turkey's modern maritime revisionism lie in the concept of "Mavi Vatan," or "Blue Homeland," a strategic doctrine originally formulated by nationalist naval officers and later adopted as official government policy. This doctrine rejects internationally recognized maritime borders, arguing that Greek islands near the Turkish coast should not be granted an Exclusive Economic Zone (EEZ) or continental shelf. Within this framework, Ankara claims sovereign rights over massive swathes of the Aegean and Levantine seas, directly encroaching on the EEZs of Greece and Cyprus. By asserting these expansive claims, Turkey seeks to overturn the territorial settlements established by the 1923 Treaty of Lausanne, which defined modern Turkey's borders. The promotion of this doctrine has been highly visible, even serving as the central theme for major national defense exhibitions such as the 2025 Teknofest showcase.
Tensions reached a critical juncture in November 2019, when Turkey signed a controversial maritime boundary agreement with Libya's Government of National Accord. This agreement drew a hypothetical line across the Mediterranean, deliberately ignoring the presence of Greek islands like Crete, Rhodes, and Karpathos, which lie directly in that path. Through this legal maneuver, Ankara attempted to sever the maritime connection between Europe and the Middle East, effectively blockading prospective energy corridors. This aggressive posture has been accompanied by the militarization of the occupied northern third of Cyprus, where Turkey has deployed advanced military hardware. Since 2021, Turkey has stationed armed drones, including Bayraktar TB2 and Akinci models, at Gecitkale airbase, directly threatening adjacent offshore gas drilling operations.
Key Dimensions of the Geopolitical Challenge
- The Blue Homeland Doctrine: Turkey's official "Mavi Vatan" policy asserts claims over 462,000 square kilometers of the Aegean, Black, and Mediterranean seas, denying the EEZs of Greece and Cyprus in direct violation of the 1982 United Nations Convention on the Law of the Sea.
- Northern Cyprus Militarization: Ankara maintains over 35,000 occupation troops in Northern Cyprus and has deployed armed unmanned aerial vehicles along with 200-kilometer-range ATMACA anti-ship missiles, capable of targeting Israeli, Cypriot, and Greek offshore energy facilities.
- Systemic Support for Islamist Groups: Despite international agreements, Turkey continues to host and fund Hamas, providing a diplomatic and operational haven for its senior leadership, while Erdogan publicly rejects the group's terrorist classification in the wake of the October 7, 2023 massacres.
Strategic Analysis of Regional Alignments
Turkey's revisionist actions have had the unintended consequence of fostering unprecedented strategic unity among Eastern Mediterranean democracies. Israel, Greece, and Cyprus have consolidated their partnership through frequent trilateral summits, joint military exercises, and shared energy initiatives. This cooperation was formally institutionalized through the creation of the East Mediterranean Gas Forum (EMGF), which seeks to coordinate regional gas exploration and bypass Turkish unilateralism. Joint military exercises, such as those analyzed by the Institute for National Security Studies (INSS), have demonstrated the growing defensive alignment of the Israel Defense Forces with Cypriot and Greek forces. These exercises are critical for preparing regional militaries to protect offshore gas platforms and critical sea lines of communication against potential naval aggression.
The broader geopolitical landscape remains highly volatile as Turkey seeks to exploit regional vacuums, particularly following the collapse of the Assad regime in Syria. According to an assessment of maritime developments by the Foundation for Defense of Democracies (FDD), Ankara seeks to position itself as a dominant regional hegemon by expanding its footprint from the Levant to the Horn of Africa. To solidify its revisionist claims, Turkey has increasingly rejected international arbitration, preferring coercive diplomacy and naval escort for its exploratory drillships in contested waters. This approach is further outlined in research by the Washington Institute for Near East Policy, which emphasizes how Turkey's unilateral maritime demarcation treaties disrupt regional stability. These maritime maneuvers, combined with Ankara's ideological alignment with the Muslim Brotherhood and Hamas, underscore that Turkey's ambitions are not merely about energy, but about reshaping the geopolitical order.
Conclusion and Geopolitical Significance for Israel
For Israel, Turkey's Neo-Ottoman revisionism represents a direct and multifaceted security challenge. While Israel has historically sought to maintain pragmatic trade relations with Turkey, Ankara's ideological support for Hamas and hostile rhetoric make Turkey a persistent strategic adversary. The deployment of advanced Turkish military assets in Northern Cyprus, within striking distance of Israel's Leviathan and Tamar gas fields, introduces a new vulnerability for Israel's energy infrastructure. Furthermore, Turkey's efforts to disrupt Greek and Cypriot sovereignty directly threaten Israel's primary maritime connection to European markets. To mitigate these risks, Israel must continue to deepen its military and intelligence ties with Athens and Nicosia, ensuring a united front against revisionism.
In conclusion, the stability of the Eastern Mediterranean relies heavily on the resilience of the democratic alliance between Israel, Greece, and Cyprus. As Turkey continues to project power through maritime blockades, drone deployments, and support for Islamist extremism, the regional trilateral partnership serves as an indispensable bulwark. Western powers, including the United States and the European Union, must actively support this alliance to prevent a revisionist state from dominating critical maritime trade routes. Upholding international law, securing offshore energy networks, and containing Neo-Ottoman expansionism remain vital to safeguarding the security of the Jewish state and its Mediterranean neighbors. Pragmatic deterrence and collective defense will ultimately determine the future of this strategic maritime crossroads.
