How, exactly? We were attacked. America cried out for blood. Bush heeded the call. Do you really think Clinton or Gore would have done anything differently?
Yes, I think they would have done something differently. Either one would have done more to give that feel-good feeling, but which would have been less effective. They would have been quick to react, committing our military before a plan was well thought out, resulting in something along the lines of bombing a pharmaceutical factory and an empty field - but on a grander scale. Their credibility among other world leaders would not have allowed either to be as successful as Bush.
They would have allowed state-of-the-art military helicopters to be sent to the front, but not allow them to be used. Oh, strike that, they already did that.
Bush's deliberate approach, completing what he promised, is refreshing and - believable.
