Starting in 1963 with the Treaty of Ankara, Turkey’s the European Union adventure has been going on with a very low momentum in recent years. In “the Arab Spring” process, due to differentiation of approach to the cases between Turkey and some European countries as well as the prominence of disagreements in political views have led to a bumpy relationship spiral. After 2015, problematic relations beginning with “the Syrian civil war” and “refugee problem” that were the reflections of the Arab Spring have raised the tension between parts in addition to the new conflicts such as “Turkey’s anti-terrorism law”, “cross-border operations” and “the Eastern Mediterranean crisis”. Due to the fact that the statements made by the parties against each other in the international arena become threatening from time to time, problems become more complicated and both parts opens up uncompromising and disputed areas showing “security” reasons. In this study, these disputed areas, which constitute the framework of the relations of Turkish foreign policy with the EU in the last 5 years, will be analyzed.
