The document identified Sunni extremists as the major factor driving the insurgency in Syria and predicted the rise of ISIS if the West continued to destabilize Syria.
The warning was quite clear, both as to who the West was climbing into bed with in Syria and what the likely out come would be. Western powers ignored the prediction, continued to arm and fund the Sunni extremists (under the guise of moderate rebels) and ISIS emerged a year later.
Also the notion that a continued US military presence in Iraq would have prevented all this from happening is frankly absurd. Six years of Western military "training" and the Iraqi military threw down their weapons and ran away from the Sunni head choppers the first chance they got.
