Pakistan should do same? They will destroy us on detection and they will not regret. This is how you treat your enemies. This is the same India whose surface vessels destroyed Karachi port. Countries show weakness because either they are too defensive or coward. In our case, It's too defensive. This is totally unacceptable. First we compromised over Kashmir issue. Now compromising our national security. No navy in the world left enemy submarine unharmed. We left them unharmed 3 times. These same submarines might destroy our frigates in future because what they see is opportunity. Give chance to enemy and get ready to Die.
