Ok; First you have the support of China. That is great, but you need three more key players on your side. - US, UK and EU. It is a difficult process and you can get them on your side if you give them what they want. Forget France, Australia, Germany etc. They will fall in place if the big three are in your net
Unlike India, all the three are business like; That means you can negotiate with them. I don't think you need a lesson on how to negotiate. You are doing excellent job with us. So give them what they want and you will get what you want. As simple as that. I believe you hold several trump cards - Afgan Victory, Mulla, OBL etc. Use this trump card wisely
For US:
Give the victory in Afghan to US. There is nothing that will make us happy as emerging victorious from Afgan. Also give'em laden, Mulla and other top guns in Taliban. Ask for their support in Kashmir. I bet you will have a positive outcome. ISI and Pakistan Army can do this if they have the political will.
Similar approach to UK and EU. Prove to them that you got rid of safe havens. Trust me they will switch sides.
India is aspiring to be a super power. They need nuclear Fuel, UN membership and wants to be recognized as a power by all the top 5. We can leverage this to address Kashmir issue
This is difficult, but possible. You need Political will to implement this tough decisions. But the good news is that majority of Pakistani citizens and the Press will back you in this project
Forget Indian noise about Kashmir being integral part etc... We know how to get them by their balls.
Are you ready?
