Like anything else, there are pluses and minuses.
The pluses are the former King Hussein, his son (current ruler) and his son's wife are all American educated and Jordan has been as pro western as you can get and not be assasinated.
The minuses are mohammed atta and 9-11.
I think the old shah of Iran was western educated.
In the 80's I went to graduate school and one of my classmates was arabian who got kicked out because he liked american girls too much to the point where he alledgedly abused his position as a graduated TA.
Except for the fact that american girls dress like tarts, on the whole they can be a very civilizing influence on the 72 virgin crowd.
If he'd been more Americanized he'd been packing heat and the fight wouldn't have happened of course.
