One way to determine if the oligarchy had foreknowledge of the terrorism is to check the records of the victims. If there are no dead generals in the Pentagon, and neither dead senior executives, senior partners, nor sons of the oligarchy (i. e., you don't see Ritchie Rich IV on the list), and find that all these people were miraculously saved as they unavoidably had to be out of the office that morning, you can draw your own conclusions.
