So we just forget about Pakistan and Saudi Arabia because their nationals weren't present on September 11/2001?
The gauge of culpability is being there to commit the atrocity as opposed to the those who gave the orders and who financed the operation?
It's enough that an XYZ person committed this violent act of terrorism so everyone even vaguely resembling XYZ types are therefore and for all time automatically terrorists and thugs?
Would that apply to Abu Ghraib or the crews who toxified the soil of Southeast Asia?
You seem to be a little sidetracked with this issue.
If I remember correctly, most of the hijackers (murderers) were Saudi nationals.
The point is both Pakistan and Saudi Arabia moved against terror organizations in their nations, however reluctantly.
Afghanistan refused. If they had turned over Osama et. al. they would still be happily hanging women for showing their wrists in public.
Mind you, given the power (which the US DOES NOT have), I would happily see Pakistan, Saudi Arabia, Iran, and Syria all occupied.
I don't like fascists, be they secular or Islamic.
