Turbulence in ties between Ankara and Washington is increasing because of developments in Turkey. Prime Minister Recep Tayyip Erdogan wants the United States to extradite or, failing that, to at least deport Fethullah Gulen, the Pennsylvania-based Turkish imam who was once one of his closest allies against Turkey’s secularist establishment, but has become his archenemy.
Erdogan accuses the ailing Gulen, 73, who has been living in the United States since 1997, of being behind the corruption investigation opened by prosecutors on Dec. 17 that examined the actions not only of government ministers, who have since been forced to resign, but also of Erdogan's son Bilal.
