Yet when the Taliban starts bragging on how they are now going to attempt for kidnapping, it is not relevant.
Kidnapping for prisoner exchange will be more highly regarded especially while we are drawing down the forces.
Kidnapping/capturing takes more resources than killing/wounded the opponent. They have to be kept away from rescue attempts; kept healthy enough to prove a point and supervised.
That takes away material/resources from the conflict
The Taliban and every single other person we've fought for decades and decades knows that captured American soldiers are enormously, enormously valuable. There is simply no question that they were already doing whatever they could to capture more.
