Well they could not take any steps even when Rajiv was assassianted. LTTE is still there.
Also it is easier said then done, posting a comment is easy blaming anyone is far more easier but running a country like India with so many cultures is not easy. We have had instances of bartering militants in exchange of civilians. Well lot of people blame Congress as if if India is governed by some other party these incidents will not happen. You think terrorists are afraid of some political party, they either ways will do it. What we need is a sound justics system, where innocents are not hanged, culprits are punished faster, judicial system is incorruptable, police is not corrupt and thrive to be a part of perfect justice deleverance. But this will still take sometime because we all know, we are among the most corruptable countries and we are working on this. We will have a day when evils we will be dealt in language they can understand and innocents will not become scapegoats. We are developing and our country is slowly inching towards it. There will be a political party which not have personal goals to achieve but whose agenda will be a better, safer and beautiful Hindustan. Inshallah, humanity will succeed and save India.
