I agree India has massively under performed but atleast India takes responsibility for it's welfare and since it's independence has largely prospered or languished based on it's own merits and demerits. In the end it's Indians who are to blame or praised.
Any other nation will primarily look for it's own interest first no matter how special the friendship. When the time comes China will dump Pakistan like a hot potato and all you will get words of support not deeds like in '65 and '71. Are you ready for that? Pakistan's fate might be dependent on China but rest assured China's fate is not dependent on Pakistan. So Pakistan has no leverage on Pakistan
As a wise man once said " Friendship is seldom lasting but between equals"
