I think we would have seen more immediate attacks without the current administration.
I think we would have seen the patriot act, and the iraq war without 9/11 with this current administration
Both statements are arguably true and not mutually exclusive. I would tend to agree more with BBallad's hypothesis than RoadClosed's, but that's just my opinion.

Its not as if Bin Laden, or terrorists in general (McVeigh included) didn't operate during the Clinton era as well. They had already tried to bomb WTC once. Perhaps they would have attacked sooner under a more miltarily lax Democratic leader.

If Vegas were laying odds though I would definitely put money down that this regime would have found some way to justify the PATRIOT Act and attacking Iraq with or without a 9/11 attack. Their attitude and actions in all other areas of government and foreign policy would seem to support this hypothesis.

That's my $.02 - not sure what the deflation rate is here in Michigan...Tiger Shark??
