There is a great deal of pent-up rage in the Arab world at America and to a lesser extent all the western world.
Perhaps some of this is due to the cultural phenomena which have prevented that part of the world from making the progress--on many levels--that so characterize the Western world.
During the Dark Ages, the Arab world was a center of knowledge, but that has been left behind.
Upon reflection I think there's a lot to be said for secrecy and covert actions. Instead of shouting from the rooftops...
There's a lot to what you say, but I think that in that part of the world strength is a trait that is greatly admired. Perhaps it is better to be feared than to be liked? Lately, in that part of the world, we have neither.
