Fifteen of the 19 hijackers in the 9/11 attacks were Saudi citizens, two from the UAE, one each from Egypt and Lebanon. None from Iraq. There was no known operational relationship between Saddam Hussein and Al Qaeda.
A bit of history about the Project for a New American Century (PNAC)
PNAC members held key positions in the White House, Defense and State Departments, among them Dick Cheney, Donald Rumsfeld, Paul Wolfowitz, Richard Perle, Elliot Abrams, Lewis Libby, and John Bolton, along with others in lesser positions. William Kristol, writer for the conservative magazine, the Weekly Standard, was chairman of the group. They called for the waging of "multiple simultaneous large-scale wars" and one of their first orders of business was always the removal of Saddam Hussein, thereby giving the US a toehold in the oil-rich Middle East. What was needed for America to dominate through a "Pax Americana" securing the world’s resources, it said, was “some catastrophic and catalyzing event – like a new Pearl Harbor”. The attacks of 11 September 2001 provided the “new Pearl Harbor”, described as “the opportunity of the ages”.
I weep that there were many people killed and continue to suffer, perhaps because of some global domination scheme...
To all the first responders, and to all that lost their lives on that fateful day...we will remember.
