Vf,
The problem with the Vietnam war and the others that have been fought after were rules of engagement, which the western world tries to abide by. Unfortunately, when one side fights with a set of rules and the other doesn't it is a war that cannot be won. Sometimes it's better to throw the baby out with the bath water, instead of slowly and inefectivly trying to not injure the innocent, who pay dearly whether they are killed or just live in a war zone for years losing friends, family, and dreams.
