Not for the civilians that die as a result of the blowback it doesn't...

Probably that we should nuke Afghanistan over the actions of a bunch of Saudis. Because for a sadly large portion of the populace, the concept of blowback doesn't exist & there are no differences between brown people significant enough to consider at least trying not to kill those that did nothing to us while attacking the guilty. That "they're all crazy bloodthirsty ragheads" is just mirror image of what OBL's crew saw in Americans is lost on us.

I wonder what Pakistan would've thought about that?

...am I tripping, or are you trying to say that if not for maintaining global hegemony the U.S. would eventually "have to*" use WMDs again in that last part?
