5-6 plotters. Hundreds of unwitting operatives. Probably 10-20 MI-6 wiring the Pentagon for maxamum damage, and 40-50 Mossad wiring the twin towers over weeks or months. One of the companies that was working on the pentagon (area that was hit by the plane) was British and was still in town when the attacks happened. And Mossad could have been used easily to come and go in Manhattan and plant the charges needed in the towers. The clandestine services keep their mouths shut, too, if that's what you're getting at. The spooks wouldn't talk, neither would the half-dozen plotters. The rest...they were just following orders. A lot of people have a PIECE of the puzzle, but the number of plotters would be minimal.

As to who the plotters were, Cheney controlled the airspace on that day and Rumsfeld was in the pentagon. SOMEONE had to turn off the phalanx gatling guns and surface to air missiles that were protecting the pentagon at the time, and the boss was in the building. So Cheney and Rumsfeld definitely.

Beyond that, who knows? I'd say Bush #1, since he's been in on every major step in the destruction of America in the past 30+ years, and Cheney and Rumsfeld are his men.

I used to think that Eberhart and Myers of the Joint Chiefs had to be involved, but maybe they weren't. They certainly aided in the coverup, but on the day of 9/11 they may have been as confused as their NORAD pilots.

No one not involved in the actual carrying out of the plot would have known all the details, unless they stumbled across them by accident, but I suspect Jeb Bush knew the whole plan. His father once called him the "smart one," and the PNAC document was copied to him a year before 9/11, so he may have been taken in to his father's confidence, since George W. would be in Jeb's state of Florida that day.

So Cheney and Rumsfeld definitely, Bush #1 probably, and possibly Eberhart, Myers, Jeb Bush and Henry Kissinger (Kissinger just because he makes daily trips to the White House and always seems to be around when trouble pops up).
