Of course Jean if the be-knighted son of the former Head of Nixon's and Ford's CIA, who later became an Alzheimer President's Vice-President, and then the President, if this son was some kind of 9-11 patsy, you'd think you were reading a Robert Ludlum Spy novel.
Except of course, Ludlum would not have crassly included the fact that both the Father and the Son attended Yale and were members of the secretive Skull and Bones Society, and that both sides of that family were heavily involved in the munitions, oil and international banking industries.
Nor would Ludlum have included that US Senator Prescott Bush, father of George Bush Senior and Grandfather of George Bush Jr., was a board member with Brown Brothers Harriman, a unscrupulous firm which financed Herr Hitler and that the assets of said firm were seized under the trading with the enemy act.
Nor would Ludlum have included some nonsensical detail that Marvin Bush, the youngest brother of George Bush Jr. resigned his position with Securicom in July 2001.
see: "George W. Bush's brother was on the board of directors of a company providing electronic security for the World Trade Center, Dulles International Airport and United Airlines, according to public records. The company was backed by an investment firm, the Kuwait-American Corp., also linked for years to the Bush family." (https://www.theguardian.com/world/2004/sep/25/usa.secondworldwar)
IOW, just because uncomfortable and accurate details make a story appear to have been torn from a spy novel's Hollywood B movie script does not invalidate what Mr. Maffei has written.
