The issue of Turkish membership has been contentious in Greece. An opinion poll from 2005 suggested that only 25% of
Greeks believe Turkey has a place in the European Union.
[118] The former Greek Prime Minister
Kostas Karamanlis stated that Turkish membership of the EU could only be predicated upon, "full compliance, full accession" in December 2006.
[119] In 2005 the European Commission referred to relations between Turkey and Greece as "continuing to develop positively"
[120] while also citing a key barrier to progress being Turkey's ongoing claim of
casus belli over a dispute about territorial waters boundaries.
[120] In September 2017, Greek Prime Minister,
Alexis Tsipras, mentioned that halting accession talks with Turkey would be a strategic mistake by the
European Union, amid a war of words raging between Germany and Turkey.
[121] Also, former Greek Prime Minister,
George Papandreou, has urged European Union leaders to keep the doors open to Turkey and to continue dialogue with the Turkish government, in an apparent reference to the former German Chancellor Angela Merkel's calls for the suspension of accession talks with Turkey.
