This is old news, right from the time Indira decided to move the army into former east Pakistan. But folloiwng the war none were sent back and no inititive was taken by the congress and the communist to do so. What we have now is over 2% of our population who have a mind sent of converting the entire land into land of the believers. And the congress and the communist actually protect these illegal terrorist. We dont need external enemies when we have both these political parties actually runninbg for the top spot in protecting such people.
