Saudi Arabia is not our enemy either and did not create al Queda. No matter if some of its citizens are. The Royal family cannot be too aggressive against the religious authorities or it will be overthrown. However, that appears to be changing.

The Royal Family created these very fundamentalists in order to secure it's hold on power.About the chickens coming home to roost,well that is another matter altogether.
