whole world knows where their Aakkas Sayed salahuddin, Hafiz Muhammad Saeed (LET) and so many blah.. blah.. chiefs sleep and eat butter chickens, now whose responsibility is this to control these animals Hizb-ul-Mujahideen, Lashkar-e-Toiba, Harkat-ul Mujahideen and so on... these all are legally banned terrorist groups operate from Pakistan, so it is Indian army's responsibility to go Pakistan and kill them or Pakistans?
