I think so. JayB just explained it pretty well, of course.
A peculiarity, to me, is the insistance of many here that Bush and his actions/policies promulgated 9/11, when he'd been in office, what, eight months, instead of what appears (again, to me) that it was a predictable progression from all the previous attacks on the U.S. of the previous twenty years.
Yes, the foreplay made it pretty obvious that we were about to get fucked. Bush is just the asshole who said yes.
