Only those who do not history will have such altruistic thoughts. We have burnt our fingers by helping the ungrateful Bengladeshis in 1971. Now they are main sponsorers of terrorism in India. They do not even remember the atrocities committed by the West Pakistan and their hatred is reserved for India only!!!!!!!! Also we cannot forget the bad experience of venturing into strife torn Sri Lanka. Let the Afghans handle their problems. We need not worry much about that. We have more than enough problems in our country itself.
