Furthermore, it has also been recently reported on the basis of intelligence supplied by an ISIS insider (Al-Arabiya's article and video on the interrogation of an ISIS/ISIL fighter captured in Syria) that Abu Faisal, also known as Prince Abdul Rahman al-Faisal, the brother of Prince Saud al-Faisaland Prince Turki al-Faisal, was the actual “supreme commander” of ISIS/ISIL. Saudi Arabia is thus in command and in charge of the ISIS and not its Iragi persona who goes under the name of al-Baghdadi and who was in US custody in Iraq from 2005 till 2009. (For more interesting background on the ISIS you are advised to look into the previous link)
Also bear in mind that al-Arabiya is a Saudi-owned "pan-Arab" news channel!
All this means whatever the exact identity of the Saudi Prince was that, in the face of the crisis and possible US strikes (however symbolic) against the ISIS in Iraq (and possibly also in Syria), Saudi Arabia is thus publicly and brazenly declaring that the beast, ISIS/al Qaeda, is its own army, child, Frankenstein monster, or bastard (whichever of these you prefer). In a word, Saudi Arabia has found a way of declaring that the monster, whether it is now an army of some 60,000 (at least) or a new state on the map of the Middle East is, indeed, theirs. This should have been a shot that ought to be talked about around the world as much as Yatsenyuk's declaration of the Kiev Nazi commitment to cleanse all the "subhumans" in Ukraine who don't like and oppose Banderite fascism, the junta, the oligarchs, and NATO expansion.
Saudi Arabia is thereby also putting defiantly the US, which already knows this parentage and foster care, on notice. By revealing that much--its own Saudi head of the ISIS/al Qaea of Iraq, Saudi Arabia clearly and quite openly demands that the US treat its ally and their joint progeny as a good ally, comrade, and conspirator. In other words, Saudi Arabia found it necessary to impose strict limits on what the US may want to do against or about the ISIS in Iraq and calls the public, especially in the Middle East, which follows al Arabiya and developments in Syria, as its witness!
In other words, through its own media channel, Saudi Arabia has made it known that attack on the ISIS would be clearly tantamount to an attack on the Saudi royal family itself. And it seems that Saudi Arabia decided that the stakes are too high and thus decided that the risk of coming out is worthy it and had to be taken.
Thus we have what appears as a deliberate strategic leak, which, of course, Western media treat as taboo--they have more important Newspeak propaganda to report.
Moreover, one cannot fail to see that the US never was much concerned about the ISIS. The US has not been ever much concerned about it. What the US really wants is to topple Maliki and, to this effect, the US is using the ISIS and its threat to achieve its regime change in Iraq No. 2. In 2003, there was no al Qaeda, but this did not prevent the US from falsely asserting that it is so. Now, more than ten years later, al Qaeda in the form of the ISIS has carved out of Iraq and Syria what is effectively a protectorate or fundamentalist emirate of Saudi Arabia. The US, however, wants to use the current crisis to remove no really the ISIS, but Maliki and with him the current Iraqi government. The fact is that Maliki did not allow the US to stay in after 2010, and his government is too pro-Iranian in the eyes of the West.
The claim of the "few thousand fighters of the ISIS" is part of the ongoing PR campaign observed from the beginning of the attempted regime change in Syria that was meant and tries to downplay and conceal the prevalent fundamentalist nature of the faux "freedom fighters" and "moderate rebels" supported by the West and the fact that al Qaeda armies form the core and the most and best trained and equipped forces of the force jointly created by the US, Saudi Arabia, Israel, Qatar, Kuwait, Turkey, and the rest of NATO in their joint push to install a new dictatorial "World Order" by means of the most reactionary militants available. This war machine is massive, it is very well trained, organized, and equipped, and it controls upwards of 5-10 million people in Syria and Iraq. Few thousand militants can never control that many.
