pressure on eastern border doesn't mean that pakistan will fight in case of invasion.pakistan will open up their own front by attacking india from kashmir side.pakistani generals know how to put india under pressure.pakistan don't need to fight on eastern border because it's strategic force will launch thousands of cruise missiles on advancing indian army but when we open another front on kashmir,india can't fire their missiles because the terrain isn't suitable for missiles.if india can make it's own cold start doctrine,pakistan can made it too but it's not public.in any case,pakistan will defend it's land but it will be hard for india to save kashmir because in kashmir,you don't have desert,you have streets,perfect terrain for modern warfare.how can india save itself in this situation lol.
