The following graph illustrates the special case in which Turkey finds itself in terms of how long it has stood at the EU's door compared to other current applicants and recent members.
The graph is taken from my forthcoming book Turkey and the European Union: Christian and Secular Images of Islam, NY: Palgrave Macmillan. I will be posting selections from the book on this blog. In the book, I try to shed light on the special challenges that Turkey's EU bid faces by looking at history and issues of collective identity.
