Scenario seven: The Chenab formula
This plan, first suggested in the 1960s, would see Kashmir divided along the line of the River Chenab. This would give the vast majority of land to Pakistan and, as such, a clear victory in its longstanding dispute with India. The entire valley with its Muslim majority population would be brought within Pakistan's borders, as well as the majority Muslim areas of Jammu.
With the inclusion of Ladakh, which also lies north of the Chenab river, India would be left with approximately 3,000 square miles of territory out of 84,000 square miles.
This solution would require the voluntary agreement of India to give up territory which it wants to retain. It is impossible to see what benefit India could derive from the transfer of so much land, and why the government - or the inhabitants of the region who are not contesting their status - would ever agree to such a solution.
It also does not take into account the movement for independence which has been extremely vocal ever since the insurgency began in the 1980s, and whose supporters have been demanding independence of all or part of the state.
