For the first part of your post "The only talks that should be taking place is their conditions of surrendering", you need the situation on the ground to be brought to the point where the other side has no option but to take what GoP offers them.
Currently, this isn't so. Which is why I was saying some serious phainty is needed and then take to talks.
Pakistan has a history of, as the Americans say "half-assing" everything. We start things that we never finish.
If the army goes all in against TTP, the civilian, provincials government has to implement rigorous punishment on the terrorists who are captured. The courts have to be thorough and expedient with cases so sentences can be carried out against those acting against the state, thus taking them out of action and circulation in the TTP.
Currently, even if the Army captures ppl, the local government and courts are not taking strong enough action. This is the reason that other measures are being resorted to which end up giving the insurgents a fillip in terms of propaganda.
