I think it was more likely some of the big manipulators like Soros or Goldman Sachs or J.P. Morgan. There was definitely some manipulation, but more likely from the NWO crowd or the banksters than “terrorists.”
The Saudis and some of the other oil sheikhs have that kind of money, but I don’t think it’s in their interest to bring down the world economy. In fact, I suspect that they’re seriously annoyed with Obama for letting things get out of hand like they have, in Tunisia and Egypt.
But it began in 2006, coincident with the Democratic sweep, and maintained through the Bush terminus.
The curious thing to me is that the "Republicans" (of which establishment I am no friend) did not make more of this correlation in 2008. It was ripe for target.
