Expect anything from Hindu.
Western route is easier to defend hence a priority.
Oh bhai.... u can build a route 1 km from Indian border and it can be defended fine
..
Tactical nukes are to deny India capture of territory in small shallow surprise thrust away from civilization...
They can also be used to wipe out indian military inside India including airforce and strategic forces. Leaving cities intact .. but that's an offensive use and never advertised ....
Any thing aiming for a vital high way city or indus river will and I repeat will result in a wipeout ... either of India or of whole sub continent....
Nuclear war is not fought on fantasies... any one who uses first and uses massively will be at advantage.....
So u can imagine what will happen if a sizable force actually tries to hit a vital economic interest
