Next stop Baghdad-—The seige of Baghdad is coming. My money is on the Islamic State. Their use of Terror has proven as effective as it was when Genjis Khan used it long ago. Each day their numbers grow—each day they smell victory. wait til they face Iran and the Republican Guard. With Allah’s help they will destroy the corrupt Saudi Kingdom and seize Mecca and tear down the pagan temples as they purify Islam. Islam needs no Kaaba!
If whoever defends Baghdad capitulates like most have where the Islamic State has already attacked, then they might take it. But Baghdad is so large that they almost have to have many troops and citizens come over to their side just to have some control over so large a city.
It does seem so far that the IS fighters are the only ones who've done any serious fighting.
