BUT this is a somewhat different issue. You see, Pak has never been successful in using SOF in war to any meaningful advantage. And creating a defensive no go area can be done in so many ways.
We are forever stuck thinking defensively. We choke like the South African cricket team whenever push comes to shove.
There is a clear possibility for building a low cost system that will cause mayhem on Indian ports and naval installations, but instead we want to do something silly like buy an expensive submarine from Italy, put SOF in them and send them to India... Or sit like a fool in its own waters to deny access to the Indians.
Our whole mindset is wrong. It is that of a country that is unsure of itself. Has no ideology.
