I agree they broke their agreement, does that mean we can wash our hands and seal borders with along FATA? .
Absolutely! How can we claim it is our territory if we can't man the border even with 100,000+ troops there. We ought to have will to clamp emergency and forced evacuation in a 5-10 miles belt along the border.
Anyone caught in that area should be shot.
Similarly the FATA should be sealed from Pakistan as well. This area is now a hell hole. We should get the innocent men, women, and children out and place them in well established camps.
Then hill by hill, valley by valley, town by town, and agency by agency FATA has to be brought to civilian control.
It will take a lot of effort, but the alternatives will result in certain Afghanization of FATA i.e. utter destruction.
