You've probably heard about
O.B. Laden's latest message to the world. The quintessence of his speech is that he's angry at the US because of their foreign policy in the middle east. Interestingly, that pretty much matches the reasons for bin Laden's ideology in the book
Against all Enemies by Richard A. Clarke. Dick Clarke describes in his book that he got toally fed up with the United Status, when they used Saudi Arabia to station their troops for the second Gulf war (freeing Kuwait, that was). In general, I would recommend buying and reading this book, as it gives a lot of insight into how the United States government and their secret services and law enforcement agencies work. It also clearly shows that Bill Clinton was not a fool, and that all these assertions about attacking other countries to draw off attention from the Lewinsky affair are simply not true (only a few months later, law enforcement agencies uncovered several terroristic cells in New York and Montreal how have been in operation for several years).
