The Taliban are an organized group. Thats why they could overthrow the Afghan government and take power if it were not for foreign assistance. There are other groups involved - criminal groups, warlord forces, etc, but the Taliban are the only ones who could topple the regime. Shoot them until they are peaceful? Dead people are very peaceful. Do you have a better way of making enemies "peaceful"? We are not there to liberate their women or indoctrinate their children. Having knocked out their government in persuit of Al Qaeda we are now there to help the new government until they are able to handle the situation themselves.
