Turkey is not a member of the EU. It isn't even an official candidate for membership, though the possibility of joining has been discussed.
Partly true:
Turkey became a founding member of the Council of Europe in 1949, applied for associate membership of the EEC (predecessor of the European Union) in 1959 and became an associate member in 1963. After decades of political negotiations, Turkey applied for full membership of the EEC in 1987, became an associate member of the Western European Union in 1992, reached a Customs Union agreement with the EU in 1995 and has been in formal accession negotiations with the EU since 2005
Although Turkey is not a official member of the EU its being considered as a EU member on a political and economical level since it agreed to the Customs Union, and its also being considered as a associate EU member thus being a EU member.
Turkey signed a Customs Union agreement with the EU in 1995 and was officially recognized as a candidate for full membership on 12 December 1999
Actually Turkey is an official candidate for membership in the EU and has almost half of the chapters for negotiating the membership with Bruxelles closed and signed. However the other chapters are far more crucial for Turkey`s membership and the political opposition against Turkey is rising in most EU countries, particularly its neighbours.
On the other hand we can easily understand how the Turkish elite feels endlessly negotiating since early 1970ies while most East European countries had meanwhile joined the EU, the most recent example being Croatia.
Maybe Beatmaster had in mind NATO and not EU...
Turkey is one key contributor members of NATO if i am not mistaken and is what? 50 years member?
This same applies for Greece they both singed the charter at the same moment.
Anyway my point is that Greece has legit claims on the disputed piece of land, however Turkey has equally legit claims.
For Greece its the claim that the land was originally ancient Greek territory however after the many invasions by loads of tribes, nations and empires it was finally granted independence by its last "invader" the British in 1960 (Zürich and London Agreement) later in the 70's if i am not mistaken the Greeks did a coup to unite the island back to Greece.
According to the history books the ONE and only legit claim Turkey has is that they must protect Cyprus and maintain its independence according to the Treaty of Guarantee.
Still that does not give them the right to annex Cyprus if they wanted to because they do not have a legit claim, if anyone has the right to annex Cyprus then its Greece.
However if you look at it in a very basic way then BOTH Greece and Turkey lost their right to make claims on Cyprus the day the Zurich and London Treaty was signed because that was the day Cyprus did become independent which was accepted by Greece and Turkey.
So if Turkey is going to annex Cyprus then it will be a part of Cyprus where one part remains Greek/Cyprus and the other part will become Turk.
But doing so will end this dispute so perhaps its better for all the involved parties. I could imagine that Greece would agree to a 50/50 deal, as it will end years and years of troubles.
