Nothing in Islam make sense ...
I'd disagree. Allied Muslim leaders slam us in public while cooperating with us in private. They know which way is up. The problem they have is populations that despise us for being infidels. That's why they have to badmouth us in public - to inoculate themselves from the charge of being American stooges.
The Shah got a little too close to the US and was toppled as a result. The Pakistani government is cooperating with the US on drone strikes. We couldn't mount them if the government objected. Drones are sitting ducks for the most basic gun-armed jet fighters, let alone SAM's. And we can't really get the human intelligence needed for targeting purposes if the Pakistani government chooses to stand in our way.
Bottom line is that bin Laden mounted a false flag attack (suggesting that the Saudi royals organized it) to get the US to topple the al Saud family and attack Saudi Arabia. That way, bin Laden could have a shot at getting 1b Muslims to rally around him in a jihad against the US.
