Rising tensions between Greece and Turkey over Aegean territorial disputes

On September 14, 2026, geopolitical analyst Savvas Kalenteridis reported a significant increase in aggressive rhetoric between Greece and Turkey. This escalation is primarily driven by disputes over the Great Sea Interconnector electrical project and Turkey's planned introduction of a legislative bill concerning the "Blue Homeland" doctrine, which is expected to open a new, contentious field in bilateral relations.

According to Kalenteridis, the friction intensified following Greek government announcements regarding spatial planning in the Aegean. Turkey responded to these plans, which encompass 152 islands that Ankara claims are under disputed sovereignty, by establishing two maritime parks that extend beyond its territorial waters. These actions serve as a direct response to Greece's own recent establishment of two maritime parks, creating a cycle of reactive sovereignty claims.

The current atmosphere remains volatile as both nations increase their focus on regional spatial planning. The situation is expected to evolve as Turkey prepares its new legislative agenda, which analysts warn could further complicate diplomatic stability in the Aegean region.
