Interesting post.
Pakistan seems to be improving with the restoration of Democracy.
We have seen the end of Arrogant empires, like hitler and napolian. The future of Chinese will be no different.
Yes ofcourse, its the "National Interest" of China to use Pakistan as a Pawn against India. Something similar, as the americans utilize the differences of Shia and Sunni muslims to its advantagem in Iraq.
Dont forget, the US is also looking to use India as a pawn against China.
Its all in...
