Barca - Did al Qaeda seriously think that murdering 3000 US civilians would elicit no response from the US? My money is betting that is exactly what they thought. Certainly they didn't expect the overthrow of the Taliban, the overthrow of Hussein, and the relentless pursuit of them. bin Laden has said that we are "Paper Tigers" and "will run at the first drop of American blood spilled". And rightly so, we have run from many provocations over the past decade.

I don't think we're talking about rational people here. If they believe it to be a victory, then it is a victory and worth trying somewhere else.

BTW: has anyone else noticed that no terrorists died in this attack? Evidently they've figured out they don't have to.
