The problem with large, powerful, power monopolizing organizations is that they stand to gain a lot more from allowing a 9-11 to happen and then reacting to it than they stand to gain from preventing it from happening in the first place.
Yes, that is the problem. Have you read the PNAC references on the front page here?
I can only speak for myself. I never imagined any group so evil they would carry out the 9-11 scenario. I did believe at that time it was planned or our TV wouldn't have played it over and over to drill it into people's minds.
That is when I found the PNAC group and read their plans for America. Most people won't even consider any of the PNAC business to be true. Not in THEIR country!
