A subsea cable does not sink because of engineering failure. It sinks because a rival power parks its claims on top of the route. That is precisely what is happening to the Great Sea Interconnector, the roughly €1.9 billion project meant to carry up to 1,000 megawatts across more than 1,200 kilometers of seabed, linking Israel to Cyprus and Cyprus onward to Greece. Cyprus Foreign Minister Constantinos Kombos, speaking on the sidelines of the U.N. General Assembly, said it plainly. Turkey is blocking the electrical connection between Greece, Cyprus and Israel through what Nicosia calls illegal claims over exclusive economic zone delimitation. For anyone who tracks maritime chokepoints, this is not a commercial dispute. It is a textbook case of using EEZ ambiguity as a coercive instrument, throttling infrastructure that would end Cyprus’ isolation from the European electricity system and plug Israel directly into the European market. The EU has already committed €657 million to the Cyprus-Crete section. European capital is on the seabed, and Ankara’s shadow is on top of it.

Look at the strategic geometry. Cyprus has been divided since 1974, when a coup backed by Greece’s then-military junta triggered a Turkish military intervention that split the island. The internationally recognized Republic of Cyprus controls the south. The northern third sits under Turkish Cypriot administration, backed by Ankara, recognized only by Turkey. Reunification talks have stalled repeatedly, with the U.N. framework built on a bizonal, bicommunal federation while Turkey now pushes a two-state solution. Kombos wants negotiations resumed from where they collapsed in 2017, but he concedes the key sits in Ankara. Secretary-General António Guterres traveled to Cyprus on July 28–29, meeting Christodoulides and Turkish Cypriot leader Tufan Erhürman to push toward a settlement. Meanwhile, the military balance is shifting. Kombos voiced alarm over the possibility of Turkey acquiring U.S. F-35 fighter jets, calling it upsetting to regional balances. At the same time, Nicosia’s relationship with Washington is, in his words, at the highest level ever. Strategic dialogue, joint exercises, NATO-compatible facilities. Washington just renewed Cyprus’ exemption from International Traffic in Arms Regulations restrictions for fiscal year 2027, and the island is now eligible for Foreign Military Sales and Excess Defense Articles.

Now project the escalation ladder. Turkey’s leverage over the interconnector rests on maritime claims, not kinetic force, and that is a deliberate calibration. Sinking a cable corridor legally contested is cheaper than sinking a ship. But every strand of this grid connects to a widening security web. Cyprus is embedding itself into U.S. and NATO logistics. Israel is seeking direct power market access to Europe. Greece is the terrestrial anchor. Ankara faces a choice: accept a fait accompli that hardwires its rivals’ energy architecture, or escalate harassment in the EEZ and risk confrontation with assets now backed by EU money and American defense ties. Kombos framed Erdoğan’s Gaza rhetoric as hypocritical and provocative, pointing to the 1974 occupation as the gap between words and deeds. That framing matters because it strips Ankara of the moral high ground it needs to internationalize its maritime claims. The realistic read is this. The interconnector will proceed in fits and starts, slowed by financial delays and Turkish pressure, but it will not die, because too much European capital and American strategic interest now sits behind it. The next flashpoint will not be the cable itself. It will be the survey vessels and escort ships sent to guard the route when laying resumes in contested waters.
