I read a theory that the division of subcontinent in 1947 into independent States was not as it is presented, as the result of struggle by people of subcontinent, but it was merely another implementation of "divide and rule". As if English had left India as a single country it may have emerged as another super power, and a threat to currently super powers. So they divided it into piece and left Kashmir and other as conflict so that countries remain busy in local conflicts and slow down their own development . Remain divided and being ruled by others.

Your analysis regarding to this will be highly appreciated.
