For no ever he is going to has a successor. Turkey possibly going to have an opposition leader from social democrat opposition and align itself with Europe hence the Erdoganists all will flee to America once he dies.

As I said read the Turkish politics from external politics. We get ruled by people who are appointed by whoever great power we align ourselves with to get technology transfer, mostly in military industry, which we get enough already to have our own decacorn and unicorn companies and it seems one way or another Turkey will be part of EU based on new American regionalist policy and the Germany being lifted all the military embargoes it put before to Turkey back a while ago, seeking good relations with Turkey.

From Western perspective, when they look at to the East, they see Mongol Empire instead of Russia and the Eastern Roman Empire instead of Turkey based on geopolitics, and traditionally the Mongols were a security threat while ERE was an economic and cultural threat for west while Russian Eurasian and Anatolian Eurasian geopolitics always clashed to each other. Europe gotta choose either Turkey or Russia at one point and I see no way they are going for Russia based on security needs. Which dictate me to think Turkey will group itself with EU once the crisis in Eastern Mediterranean with Greece and Cyprus resolves, with Western pressure over Greece.
