Despite the mixed EU-Turkey relationship, I think it's in the EU's best interests to set aside political differences or reservations and to accept Syrian refugees from Turkey. After all, the EU has accepted Syrian refugees via other routes, some in desperate situations, and therefore should practice what it preaches regarding inclusive society and accept Syrian refugees regardless of where they are from. Of course, if there is a safe space for the refugees in Turkey, that should first be considered (in no way should the conflict in Syria be a route for those fleeing to enter the EU, regardless of their situation). Of course, one you open the flood gates it can be difficult to close them (how many people do you allow in?), but to an extent the EU must take an 'act now and strategise later' policy as there are thousands of people in desperate need and countries within the EU could help solve that by offering those fleeing Syria the possibility of a better life – there are high-skill workers.

Turk-Syrian border is thought to be world’s easiest border to cross. When the civil war started in Syria, many Syrians moved to Turkey, aiming their way to Europe by entering Greece. Turkey can only hold these refugees for a limited time in its refugee camps but it cannot get these refugees settled in.

There was an irregular and immense flow of immigrants who tried to cross the Greek border through sea. There were many refugees who were died during this migration. After all these crisis and management flaws, EU decided to make a deal with Turkey.

According to this deal all the refugees from Greece will be returned to Turkey. And in return Turkey will resettle the Syrian refugees in Europe. EU made this deal to organize the inevitable arrival of Syrian refugees and to save the continent from terrorism.
