Cyprus-Turkey conflict blocks EU-NATO security cooperation as Europe reshapes defense

Turkey and the Republic of Cyprus, members of NATO and the EU respectively, are locked in a decades-old dispute that is now obstructing coordinated security efforts between the two blocs at a critical moment for European defense architecture. The deadlock has become strategically significant as Europe seeks to reorganize its security posture, potentially independent of U.S. involvement. The DW analysis argues that this single unresolved territorial and political conflict is capable of derailing broader institutional cooperation between NATO and the EU at a time when both organizations are accelerating integration. The underlying Cyprus dispute—involving Turkish military presence and the island's political division—remains unresolved since 1974.
