The Taliban is part of the local population. They will definitely intimidate, kill, terrorize but it's not the same.
EDIT: Just to be clear... I'm not proposing the US behave like the Romans used to. If anything, given the limitations it should have been more careful in the way it applies force.
Suffice to say, after a while nobody wanted to fight the Mongols. The subjugated did what they were told, because anything was better than the alternative: they might keep your prettiest daughters as sex slaves (if the daughters were lucky), kill you and all other members of your family, kill your dogs, kill your cows, kill the chickens, and then burn down the entire city for kicks. Maybe they even killed the rats.
Then they'd send back a scouting party a couple days later to execute any survivors who someone escaped the first massacre.
In other words, be the Taliban.
