The survival of the strong Sunni Sufi identity in Turkey has real reasons behind it established on ground. It is not sheer luck! Anatolia is very hard to purge. It is huge. Konya is an immovable city and so are Erzinjan, Erzurum, Diyarbakir etc. But isn't it the case that the Sunni Arabs have mighty historic Baghdad and Damascus and Tarim etc, then what happened to them? Tarim is under Salafis, Baghdad under Twelvers, Damascus under Nusayris. To answer the question, an observation of Egypt and Sudan and Morocco in contrast would help. What is required is a living civilization!, a Sunni civilization, and sense of belonging, not the local tribal family or confederation. Similarly, Afghanistan is immovable, Bukhara is immovable, and so is Ajmer, Data Darbar, Gesu Daraz and Multan etc.
