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.
We need to seal border with Afghanistan and anyone in the forbidden zone to be shot/bombed at sight would work wonders. Militancy may not go down immediately but will definitely choke supply lines of the militants. As next step after sealing border with Afghanistan we'll need to protect militants infiltration to other parts of Pakistan.
