The Bin Laden construction firm was well before the Saud's took power, they gave the Sauds the finance to build Saudia Arabia after they took control of the country by tribal warfare from guns first brought in by the British. In return, they've been able to have such an influential status in Saudia Arabia.
* After Desert Storm UBL stepped up his terror campaign against the West (he was upset that the al-Saud family did not let him coordinate Saudi Arabia's defense against Saddam...and allowed unbelievers to defend the land of Mecca and Medina). At this time he was disowned by his father and siblings.
Osama Bin Laden was angry at his country for having foreign troops on Saudi soil, that is one of the reasons he did what he did, or what we think he did, or what they made him do, or whatever.
* On 9/10 the Elder Bush was in DC attending a meeting of the Carlyle group...at which a brother of bin Laden was in attendance. The next morning the Elder Bush (and his wife Barbara) boarded a plane for a Midwest speaking engagement. He was actually in the air when the attacks occurred and like everyone else in the US...was forced to land.
Never heard of that, but what I do know, at least from what I've read from some sources is that their was a group of Saudis in America who were the only ones allowed to fly out that day.
Long story short, American politicians had a great relationship with the Bin Laden family, and they both profited heavily, and they're all scum.
