I don't know about the videos where Indian soldiers are running away from stone pelting Kashmiri women but I have seen videos where unarmed kashmir men are kicking fully armed Indian soldiers and making them say death to India. You can see the fear in their eyes.
Trust me, no one in Pakistan will lose sleep over Hindu terrorists who are ruling India and their plans to make another syria in Kashmir. You want to use air power, tanks, be our guest, nothing will please us more, you will be right where we want you to be. Ever heard about escalation ladder? Those AK47 carrying freedom fighters can easily be equipped with anti tank and anti aircraft missiles. This will give us huge impetus to expand anarchy further in mainland India, through kashmir ofcourse.
As for American leverage over Pakistan, it is what saved India back in kargil. Without it, we will be free to do as we please.
For CPEC, everyone knows how America is twisting and turning in misery over it and on record shown it's uneasiness over how it will be used by China in geopolitical chessboard and ME energy affairs. You are free to believe otherwise however.
Actually I was referring to North east as opposed to India north west. China eyes territorial soverinity and merger of these lands in China under "one China" policy. Which btw Pakistan support. It is given that this "you rub my back and I will yours" understanding, both China and Pakistan will coordinate their efforts to wrestle control of these respective lands from India. If China can block Massod Azhar being labelled as terrorist in UN, those who think that China will not support Pakistani designs in Indian occupied kashmir, are living in fools paradise.
