The reason I ask is ,because my dissertation is dealing about refugees. More specifically, the title of my dissertation is: Refugee families in the Municipality of Heraklion: Τhe example of the attachment center for immigrant integration. I want to understand first of all, why the crisis started in 2015 as wars in Middle East countries existed before. Second, how did they all decide to went to the same place? Thirdly, how do we distinguish the population of immigrants and refugees ,who came to the European Union, at the same time after there were cases of fake passports and identity cards?
