That would seem to be the original idea. Unfortunately, it has morphed into a show trail.
The genesis of jihadism began in Iran in 1979 when a weak US President named Jimmy Carter allowed the jihadists to hold America hostage for over a year.
This commisssion is fixated on 8 months in 2001 and one President George W Bush.
An honest look would be examining the Church Commisssion, the hostages in Iran, a tepid response to Lebanon and airline hijackings and bobings, 8 years of a Clinton administration that allowed jihadism to flourish and a Congress that stood by and let it all happen for 25 years.
Why does Dickhead Clarke get more time than George Tenet, James Woolsey, Louis Freeh, et al?
Inquiring minds want to know.
