There is some question of course whether Erdogan is a devout Islamist, or whether Islamism is the vehicle he’s riding to the power all dictators want tow wield.
It’s seem pretty likely some of commie dictators weren’t really true believers either. Not that this was much comfort for their victims.
Turkish Islamist leader, M. Fethullah Gulen, who lives in the U.S., has become a U.S. citizen I believe, and heads a movement very active around the world especially in Turkey worked closely with the AK Party and Ergodan.
Both Islamist movements worked for years infiltrating all aspects of Turkey's society.
Lately I believe there's been a falling-out between the two.
