Does India really need Kashmir?

The Jammu and Kashmir(J&K) state - A disputed land between India and Pakistan. A dispute that has been hanging in air for decades. Both the country trying to justify their ownership on the land, with kasmiris having a confused opinion about their own will.
The problem doesn't lies as it appers to be, the roots of this have gone deep into past and the religions rift between the two major religions of India- Hindus and Muslims. A major portion of Kashmir which lies towards Pakistan is populated with muslim population, while a very small portion towards India has a majority Hindus. India and Pakistan were born out of a single country in 1947 on basis of religion. Being the border state J&K and Punjab- two sensitive states of India had seen gross atrocities during division. And hence a pakistan supported terrorism industry started harvesting its crops on the religiously sentimental human mentality. Though Punjab was grossly populated with people belonging to a religion "Sikh"-a religion which finds its roots and similarity in hinduism, still the rift were deep after Hindu - Sikh riots of 1984. Kashmir politics more closely revolves around Hindu-Muslim rift.
Though Punjab terrorism was curbed by a cruel and oscene suppression by Indian army, the same cant be expected in case of Kashmir. India has grown over time to be a sensitive and welfare state. Though a secular state, the mentality of India as a state still cant find a very high confidence in muslim mass-thanks to regular bomb blasts in Indian cities. A worldwide misuse of "Jehad" has further spoiled the face of Islam.
A major portion of annual Indian budget goes to fighting terrorism in Kashmir. Had Kashmir come in mainstreams, it wud be a well developed state by now. Considering its beautiful landscape - commonly called "second to heaven"- it wud be an international hub for tourism. But a troubled land is never better than its troubles. Even if kashmir is brought on track it can never be trusted again. Kashmir is just a land mass for Indian common man which we dont want give up for sake of our pride. We have lost belongingness to the people who inherit this land mass. Personally I do concern when 4 people are dead in Delhi today due to collapse of a bridge, but not when another 40 die in kashmir during terrorist enconters. My senses have started accepting "thats thier destiny".
