Re the Saudi connection, here is a link you might use, it is from the Canadian Broadcasting Corporation Program called the Fifth Estate, a well-respected documentary program here. It details the relationship of the Saudis and the Bush family:
CONSPIRACY OR COINCIDENCE?
Is it a conspiracy or a coincidence? There is a long and tangled history between the Bush family and the elite of Saudi Arabia.
It begins in the 1970's in Houston, Texas, when George W. Bush was just starting out in his family's two businesses of politics and oil. The powerful - and very rich - Bin Laden family helped fund his first venture into oil.
The cozy friendship continued for decades. After a terrorist attack at a barracks in Saudi Arabia which killed 19 Americans, the bin Laden family received a multi-billion dollar contract to re-build. And incredibly, George Bush Sr. was in a business meeting at the Ritz Carlton Hotel in Washington on the morning of September 11th with one of Osama Bin Laden's brothers.
Below is a timeline that details the relationship between the Bin Laden and Bush families that culminates in the tragic events of September 11th.
