A quote from Eric Edelman, U.S. ambassador to Turkey, 30 December 2004, published by Wikileaks:

"We have also run into the rarely openly-spoken, but widespread belief among adherents of the Turk-Islam synthesis that Turkey's role is to spread Islam in Europe, 'to take back Andalusia and avenge the defeat at the siege of Vienna in 1683' as one participant in a recent meeting at AKP's main think tank put it. "
