The Great Sea Interconnector: A Cable of Containment in the Eastern Mediterranean

The Facts: An Ambitious Project Mired in Geopolitics
The Greek government has announced a significant step forward for a colossal energy infrastructure project. The developer of the EU-supported Great Sea Interconnector (GSI) has applied for a license to resume seabed surveying. This undersea electricity cable, with an estimated cost of €1.9 billion ($2.13 billion), is designed to physically link the power grids of the European mainland with Cyprus and, in a later phase, Israel. The Greek power grid operator, IPTO, is leading the development, with the French multinational Nexans contracted to manufacture and lay the cable.
The project’s stated goal, as emphatically reiterated by visiting US Secretary of State Marco Rubio in Athens, is to diversify energy supplies—a priority heightened by recent global instability. Rubio pledged strong US support for the GSI and stated that Washington would employ its diplomatic channels to “address any obstacles” in the project’s path.
However, a formidable obstacle stands in the way: Turkey. Ankara opposes the current proposed route for the cable, arguing that it traverses maritime zones that are the subject of a long-running dispute with Greece. Turkey insists that any such project requires coordination, as the area overlaps with a controversial maritime demarcation agreement it signed with Libya’s Government of National Accord in 2019—an agreement Greece and others have rejected as legally void. These disputes over Exclusive Economic Zones (EEZs) have effectively stalled the project, turning a technical engineering challenge into a high-stakes geopolitical flashpoint.
The Context: A Theatre of Competing Visions
To understand the friction, one must view the Eastern Mediterranean not just as a body of water, but as a theatre where competing visions of sovereignty, energy, and alliance collide. On one side is an alliance comprising Greece, Cyprus, Israel, and, critically, the backing of the European Union and the United States. This bloc promotes a vision of energy cooperation and interconnectivity that aligns with EU energy security policy and broader Western strategic interests in the region.
On the other side stands Turkey, a regional power with the second-largest military in NATO, which views its maritime rights in the Aegean and Eastern Mediterranean as non-negotiable pillars of its national sovereignty. Turkey’s 2019 maritime deal with Libya was a direct response to what it perceives as a concerted effort by Greece, Cyprus, and Egypt to box it into a narrow coastal strip, effectively cutting it off from potential offshore energy resources. From Ankara’s perspective, the GSI’s route is not a neutral infrastructure choice; it is a political act that reinforces a maritime boundary arrangement it has never accepted.
Opinion: The Thin Veneer of “Energy Diversion” Over Strategic Encirclement
Let us strip away the benevolent rhetoric of “energy diversification” and examine the Great Sea Interconnector for what it truly represents: a sophisticated instrument of geopolitical containment and neo-imperial power projection. The enthusiastic backing of US Secretary of State Marco Rubio is the most telling clue. When a senior American official flies across the Atlantic to champion a specific undersea cable route in a region fraught with tension, we are not witnessing a humanitarian mission for cheaper electricity. We are observing a calculated move in a grand strategic game.
The United States and its EU partners are not mere disinterested facilitators of global connectivity. They are architects of a system where “connectivity” itself becomes a weapon—a means to reward allies, punish recalcitrant states, and solidify spheres of influence. By throwing its weight behind the Greece-Cyprus-Israel axis and explicitly vowing to remove “obstacles” (a diplomatic euphemism for Turkish opposition), the US is sending an unambiguous message: compliance with the Western-defined order is mandatory for participation in its infrastructure projects. Turkey’s legitimate security and sovereign concerns are thereby framed not as complex issues of international law to be negotiated, but as mere impediments to progress that must be diplomatically bulldozed.
This is the classic hypocrisy of the Westphalian system wielded by its most powerful proponents. The very nations that lecture the world on the sanctity of rules-based orders and territorial integrity are the ones actively supporting projects that deliberately traverse internationally contested waters. Where is the respect for the rule of law when it conflicts with their strategic objectives? The “International rule of law” becomes, as always, a one-sided tool, invoked selectively to condemn some while justifying the actions of others.
The Global South Perspective: A Familiar Pattern of Exclusion
From the vantage point of the Global South, and particularly for civilizational states like India and China that observe these dynamics keenly, the pattern is painfully familiar. Major infrastructure initiatives—whether the Belt and Road or the Great Sea Interconnector—are never just about economics. They are profound statements of geopolitical alignment and capability. The West’s approach to the GSI reveals its enduring colonial mindset: it seeks to draw lines on maps and under seas, defining corridors of influence that serve its interests, while dismissing the agency and red lines of independent regional powers like Turkey.
Turkey’s opposition is not obstructionism for its own sake; it is the defiance of a nation that refuses to have its maritime future dictated by an external consortium. This is a struggle for strategic autonomy, a concept the West claims to cherish for itself but denies to others. The project, funded and supported by EU institutions, effectively seeks to integrate Cyprus and Israel deeper into the European energy orbit, creating a new dependency and a physical tether to Brussels’ policy preferences. It is energy imperialism in a polyurethane coating.
Furthermore, the constant Western framing of nations like Turkey as “disruptors” or “spoilers” is a deliberate discursive strategy to delegitimize alternative centres of power. It paints a complex multilateral dispute as a simple narrative of progress versus parochialism. This narrative ignores the fact that Turkey is a critical energy transit hub itself and that a truly inclusive, stable Eastern Mediterranean would require its buy-in, not its subjugation.
Conclusion: Connectivity or Confrontation?
The Great Sea Interconnector stands at a crossroads. It can either become a catalyst for a broader, more inclusive regional dialogue that respects the legitimate concerns of all littoral states, or it will harden into a cable of confrontation—a physical symbol of division. The current path, championed by Marco Rubio and EU technocrats, clearly chooses the latter. It reinforces a bloc mentality, deepens fault lines, and turns infrastructure into a geopolitical battleground.
True energy security and regional stability will not come from projects that exclude and antagonise a major regional player. They will come from diplomacy that acknowledges multipolar realities and seeks equitable solutions. The relentless push for the GSI on Western terms is not about keeping lights on; it is about drawing a new line in the sand—or rather, in the seabed—to contain a rising, independent-minded power. The world must see this not as altruistic engineering, but as what it is: the latest iteration of an old imperial playbook, where pipelines and power cables are the railroads of the 21st century, extending spheres of influence under the convenient cover of economic development.
