Baghdadi knows he can't be a khalifa unless he controls Mecca and Madina, and he also knows 90% of Saudis r Pro IS n from amongst security forces n the military he has many followers, he can take SA so easly, he just needs to do it right and at the right time, thanks to the stupid House of Saud of course, they made a case against themselves, they burned all their cards n now they say ''في اعناقكم بيعة لنا !!! " , but No one will listen to them anymore, they betrayed Egyptians n Financed the modern day Pharaoh, they betrayed Iraq n Yeman before that, done nothing for Palestine n Syria ...
their scholars are expired n nobody listens to them ... I am sure the Saudis will switch of sides at the first contact with IS .
