Well it was under govt control, until that control was lost. Thats why the Army had to go in, as the Taliban had effectively taken it over. Unlike in Swat however, Southern Punjab is not in the hands of the Taliban in the same way that Swat was. It may become that way, IF there not careful, but as of right now, there in no indication of something similar happening there.
So for now, S Punjab would be a police matter, and doesnt require an Army assault…
