2 things.
1. Erdogan is using democray to create a personal kingdom along the same lines as every other Arab and Islamic dictator the past 50 years. That 700M $ palace he is building for himself replete with gold plumbing is more like Baghdad, Riyadh, Damascus and those in Egypt and Libya under Mubarik and Khadafi than Bonn, Paris, London and Washington DC.
He has no intention of leaving it. And like Saddams final years his rule is becoming more Islamist by the day. The word democracy is loosely applied to Erdogan
2. What we have found out about Gulen the last few days suggests US intelligence has been monitoring his every email, phone call, text and conversation for a long time. He would be a treasure trove of intel. The 2 way communications between him and whomever in Turkey or anywhere else would be gold and make up for a lack of human intel on the ground, which is always the major and critical gap for Intel collection. No intel agency would pass up such an opportunity.
