Naa, your post, like some rabid dog foaming in mouth ready to bite anything Pakistan, is quite visible in its hateful yet zero logic message. Not very hard to reveal people's true nature.
Their numbers are thinning down as we speak. They are being blown to bits, their leaders are being hunted like dogs, ammo dumps/ factories being destroyed, ranks diminishing which is why they turn to brainwash 15 year olds to carry out their dirty work... and military has not yet announced a full scale operation. (Judging by your hateful nature, I can tell this hurts you.)
Their defeat/ bloody nose in Pakistan may compel them to make a cowardly retreat to Afghan where still much land is under Taliban control. Even if they do go back, they wont ever be able to regain their full strength. Their first fight will be with Afghan national army, who in trouble will call for NATO assistance or NATO upon leaving will provide them with some Air force to keep an upper hand. Even NATO wouldn't want to some day return to Afghan for a second cleanup.
Pakistan made a choice back in soviet era, call it a mistake or the only option at the time. PA at-least, if not govt, will not allow this scum to come back with strength now that they know the snake bites.
