The reason we didn't send in our own people was
1. The Afghans knew the terrain better, since they live there, and it would have been unnecessarily hazardous to our soldiers to send them into heinous terrain when we didn't even have good maps of the area.
2. We lacked the capability to deploy large numbers of troops rapidly, we had neither the airlift capacity nor the regional bases that are needed to do what Kerry talked about doing.
Tommy Franks on CNN after the debate said we never got confirmation where Bin Laden was. He had many reports that he was in other locations. Amazing Kerry can repeat such an irresponsible charge in a Presidental campaign
