I really don’t think Erdogan could re-create anything like a new Ottoman Empire in the imminent future, he doesn’t have the power, but he does want to be recognized as the new “Caliph” I suspect.....
“he doesn’t have the power”
Alone, no. However, what if he isn’t acting alone? Reportedly Russia tipped him off about that “coup”. Now he’s moved into Syria, supposedly under active Russian military protection, and the Russians haven’t lifted a finger to stop it. I think that can only mean Turkey, Russia, and Iran are unofficially allies now.
