Well Pakistan should throw in some incentives, like unadulterated access to CA, unadulterated access to Kashmir for all Kashmiris, and shutdown of all groups let, ssp, etc. Pass a law which prevents any party from advocating violence in another nation, they don't even have to mention India just generalize it and the mullah will have nothing to complain about since India was never mentioned. Boost trades from all borders and India should also be given an opportunity to invest in gwadar, if it means China not getting a naval base in exchange for the little valley plus trade profits through the route it would sweeten the deal. Plus neither side declare victory and you got the total end of conflict. If you want to do one last exchange of populations throw that in there and live in peace.
I hope you stick with these views as you go up in US politics lol
