After the second world war, Pakistan spilt into 2, Bangladesh and the other Pakistan.
Kashmir which is mostly muslm however was a thorny problem, the british encouraged the Muharajah of Kasmir to offer his state to India as a result of the independance of the country, howver Pakistan's military refused to accept this, hence the current state of war. However, it was reported in the Times newspaper today that there is now a two week ceasefire in the line of control.Hopefully this will lead to a permanent ceasefire.

Pakistan and India have nuclear weapons now, but the western civilised world should take itself to task and ask why they gave the knowledge and experise to both countries to do so.
