Think again. Most of the terrorists in the Al-Quaida leadership structure are from very wealthy, highly educated Saudi families. Mohammad Atta's father is a prominent surgeon. If you read the profiles of the 19 hijackers, many were from wealthy Saudi families.
An even scarier idea is the number of muslim "students" being taught in our Universities. These students are going from the college campuses straight into OUR hi-tech, pharmaceutical, government, bio-tech, and financial institutions to work. To think that they have not already infiltrated every level of our financial structure is pure folly. INS has not placed any checks and balances into the student visa's and we have paid, and will pay the price.
There is a significant prision population that has converted to the muslim religion. They are being trained to utilize computers and other hi-tech equipment, as a way to help them find work when they are released. We also have major corporations, including financial corporations using the educated prison population as cheap labor to process sensitive customer information.
Even the most recent attack we thwarted, an attack on ships near Gibralter, was a repeat of the Cole attack scenario. I'm still not convinced that these losers who are attacking us are the brightest bulbs.
