Man, you are just blabbing nonsensical things and seem completely out of touch with the origins and aims of Qaeda. The Saudis and the Reagan admin supported the original Afghan/Arab fighters that were the precursors of Qaeda and the Taliban. They did this because it was during the cold war and after the Soviet Unions invasion of Afghanistan. The 'Red Threat' was the no.1 strategic and security issue for the U.S., and Islamic terrorism was not yet in its infancy. After the Soviets withdrew from Afghanistan, Iraq invaded Kuwait (non-related). The Saudis (and the U.S), fearful of an Iraqi attack on the Saudis, set the stage for the deployment of thousands of U.S. troops to Saudi.
Bin Laden, then still not the terrorist he had become, pleaded with the Saudis not to let U.S. troops on sacred Saudi soil (home of Mecca and Medina) and that he and his militant group would help the Saudis fight off any Iraqi attack. Obviously, he was ignored and that rattled his cage. The House of Saud AND the U.S. became his enemies then. He and his followers (then becoming Qaeda) then conducted several terrorist attacks against the Saudis as well as the U.S. The House of Saud and Qaeda are mortal enemies each going for each others throats.
The 'Wahabization' the Saudis undertook, and which ultimately brought about the likes of Bin Laden, came about after the Iranian revolution (79-80). The Iranians are Shia Muslims vs the Saudi Sunnis, and they have viewed each other with great suspicion and hostility. The Saudis tried to spread their brand of Islam (Wahabism, and which is virulently anti-Shia) to counter the spread of Irans influence in the region. Basically in a nut shell. You can spout off all sorts of catch phrases (global madrasas, etc) to indicate you may have a clue, but I dont think you do.
