Tell him, we don't care what a bunch of Kashmiris think. We are a democracy and decisions are based on majority, not on demands of a small group of people. If he wants he can come back and hurl rocks. But Nothing will change.
Kashmir's fate resides in Kashmir's decision. Not some people who have absolutely nothing in common with them yet claim that its an 'integral part.'
And if India is so 'democratic' then go ahead and put up a 'democratic' vote of Kashmirs fate. We'll see if 'nothing will change.'
