And if it wasn't?
I think the whole problem stems from the same acquiesence to the Saudi Royal family that has been notorious since the days of Kissinger's deal-making. If it is found to be clear that the family is being extorted into building [terrorist-training] madrasses worldwide by the likes of OBL and others, I think then they do not deserve the time of day.
The U.S. has meade enough concessions to those who openly spread terror. Guiliani was right to refuse them and the Saudi Royal family is wrong to try to spin Sep. 11th as at its roots caused by the U.S.
The inability to completely deal with the problem means that it will grow and matasticize later.
