lol , Pakistan Army is not Defending anything .. they are defending their Housing Projects, kick backs , and kids who are mostly living outside Pakistan.. they protect their Cantonments where they live in huge Bungalows while the common people died in Drone strikes ..
Today US has start a new Chapter in Striking first in Baluchistan , and soon you will heard the news of Drone Strike in Punjab and even Karachi ..
and just wait, you will see how China React over this , cause now their so called CPEC is under direct threat from Drones .. lol you call them defenders lol they are even worse than security guards.
