Hello,
I just wanted to make a suggestion for the research question for the dissertation as the thesis currently has its arguments yet not one single route/a strong research question to build up on. The role of islam (religion) may be a good one to discuss in terms of the hesitance on the Turkish side of the relations. The doubts rooted in the EU perspective in terms of religion are well known (the 9/11 attacks, London bombings etc did significantly deteriorate this image) yet the reluctance and hesitance leading to unwillingness to perform progress on the Turkish point of view may well be related to the role of rising Islamic character in Turkish politics due to the Islamic rooted AKP government. Ali Carkoglu (listed in the sources) portrays in his article that the poll results show that the more religious/pious the person is, the less he/she favors EU membership. We can easily discuss the segmented/fragmented/polarized Turkish society in terms of religion: AKP (Islam rooted ruling party) vs CHP (Kemalist secular opposition party); Hak-is vs Turk-is (labour unions); TUSIAD (secular old Turkish business elites) vs MUSIAD (the recently emerged Muslim Businessmen Association that grows hand in hand as AKP gains more and more power.)
