Al-Baghdadi has declared himself as "Caliph" and as "the emir of the caliphate known as the Islamic State," using his real name Ibrahim Awwad Ibrahim Ali al-Badri al Samarrai, but who is more commonly known as Abu Bakr al-Baghdadi.
Forget all speculation as to who the Sufyani may be or from what nation, he has now arrived. By declaring himself emir of a nation spanning regions in both Syria and Iraq, "Big Daddy" is also declaring himself "The Sufyani." The question one must next ask is will he also fulfill the Jeremiah prophecy concerning the final "Nebuchadnezzar, king of Babylon (Iraq)?" Note that the "Baghdad" in "al-Baghdadi" is interchangeable with the name of Iraq's capital.
Undoing the Balkanization (artificial borders) of the Middle East is a good thing, but not under the aegis of Islamic extremists like al-BigDaddy. The militant leader of the former ISIS is calling for Muslims to help build his Islamic State:
We must also watch his movements regarding Jordan, northern Israel, and Egypt (especially around the Red Sea) to see if he is also the prophesied "King of Babylon."
We must also wait to see if there is a well-coordinated Shiite resistance by Muqtada al-Sadr. If he manages to defeat al-Baghdadi, then al-Sadr may then likely become "Nebuchadnezzar, king of Babylon" and there will be no Sufyani.
