There was a dialogue in recent Indian movie when RAW chief tells PM of India about LTTE,
We are not fighting with a traditional force, which has laws and honors, we are fighting with immoral fighters who doesn't play by rules. They don't follow the basic decency among soldiers.
Indian Army and Pak Army may be worst enemies but still they try to follow war principles as much as they can.
That's why you can't deal with these terrorists with negotiations. Only way is through bullet. Unmarked graves main daalne padenge.
But at the same time, other people has to be taken into confidence and rehabilitated for some time.
A Pakistani Ret. Gen. said in an interview, this is becoming a war of attrition, better we go in for all rather than loosing soldiers every other day.
Gale kaat ke phenkne padte hain in terrorists ke. No one is left alive whether he fights or surrenders.
