There is no need to draw imaginary lines connecting the dots for the origins of AQ attacks. We know exactly how AQ began and why.
When the soviet union tried to take over Afghanistan the Islamist were opposed to the Soviet imperialism. The US opposed it too and supported the islamists making them stronger. Then:
"Following the Soviet Union's withdrawal from Afghanistan, Osama bin Laden returned to Saudi Arabia. The Iraqi invasion of Kuwait in 1990 had put the country of Saudi Arabia and its ruling House of Saud at risk as Saudi's most valuable oil fields (Hama) were within easy striking distance of Iraqi forces in Kuwait, and Saddam's call to pan-Arab/Islamism could potentially rally internal dissent.
In the face of a seemingly massive Iraqi military presence, Saudi Arabia's own forces were well armed but far outnumbered. Bin Laden offered the services of his mujahedeen to King Fahd to protect Saudi Arabia from the Iraqi army. The Saudi monarch refused bin Laden's offer, opting instead to allow U.S. and allied forces to deploy on Saudi territory.[56]
The deployment angered Bin Laden, as he believed the presence of foreign troops in the "land of the two mosques" (Mecca and Medina) profaned sacred soil. After speaking publicly against the Saudi government for harboring American troops, he was quickly forced into exile to Sudan.
On April 9, 1994 his Saudi citizenship was revoked.[57] His family publicly disowned him. There is controversy over whether and to what extent he continued to garner support from members of his family and/or the Saudi government.[58]"
Bin laden was pretty ticked at the US for first supporting him and then supporting his family but not through him that he began is attacks directly on us.
Now if you think the US should have allowed the Soviet union to take over the middle east or that we stopped the soviets for oil then you would be right. Or if likewise you think the US should have not been involved in the invasion of Kuwait then again you would be right. But most people think it was wise to stop the soviets and to go to kuwait.
