When it comes to Indian Politics, the answer to the chicken and egg question is very simple and easy. It is a Gandhi, who comes first; always, by default, without a question!
Congress in last seven decades did what British did i.e. divide. Congress ran an occupation in India exactly like the British did. Add more castes in the census then divide the states and constituencies based on the caste stats, inflate the numbers and rule.
Kashmir is still witnessing brain drain. The state would continue to suffer and no body can help it except the Kashmiri Permanent Residents.
The situation in Kashmir deteriorated only because militants were at the places where they shouldn’t be. Who let them in?
Terrorists from now on will have to think about the safe havens for themselves, because Pakistan is not safe for them any more. This fear is good. Fear is an excellent deterrent.
BJP did try to change the normal set by your party over the years by successfully quarantine terrorism to Kashmir, and did not let terrorist blow up trains and buses in Mumbai, Pune, Delhi, etc.
How would you live when you know that your loved one might never return? The feeling that you would have then is called FEAR.
