In addition to coldtea's point: Saudi is in some respects the bizarro version of the US. While we export American Idol and McDonalds, they build schools teaching extremist Islam all over the world. Many formerly more moderate countries have gotten much more theocratic in the last 20 years, and Saudi evangelism funded by oil money has played a huge role.
For example, when I visited Bangladesh in the early 1990's, seeing veiled women in the capital city of Dhaka was unusual. It's very common today.
