Remember when we launched the attack in Afghanistan? The naysayers were saying we were going to get bogged down in a quagmire and we would take a lot of casualties.
The reason that we were so successful in Afghanistan is precisely because President Bush took the time to plan the action and lay the ground work before launching the attack. The plan was greatly escalated after 9/11 but the overall strategy was being developed and things were being put into place well before 9/11.
This is the difference between lobbing cruise missles at empty tents and swating flies, which is what Clinton did, and had little to no effect at all.
