Spengler is absolutely wrong here. Turkey under the Islamic Welfare Party’s Erdogan is not anti-Muslims Brotherhood. Turkey all but went to war to help the Muslim Brotherhood and Al Qaeda take Syria. It armed teh rebels, gave the sanctuary, and provoked a border clash. the Gullen Movement and AKP only differ with the Muslim Brotherhood over which Islamist group gets to create and lead the new Caliphate. The AKP want ti to be in Instanbul again, and the Arabs in the Muslim Brotherhood look to Jerusalem, if not Mecca.
Spengler generally is wrong.
