Aren't you really forcing me to accept what you are saying
Really pushing as "for the last time" or else :p
Size of navy matters less when you have to pass through sea touching our coast for hundreds of miles. Even couple of JF-17s with anti-ship missiles would block India's trade route.
Once again, no. They can't.
No trade route can be blocked because that trade route has
thousands of ships going all over the world. To be able to block that trade route, Pakistani ships would have to board each ship individually to check where it is headed.
Lets assume Pakistani navy magically increases to
10 times its current size - and we are talking about surface ships here!
Even then it won't be
halfway close to the strength required to ensure that India bound ships are stopped!
Even there it is easy to change the ledgers to show other destinations!
And most of those ships have Indians serving in some capacity in that region!
Lastly, on the other hand, consider this, India can within the first 24 hours of hostility bomb the 3 Pakistani ports - of which only 1 currently has major unloading infrastructure though the second one is getting it slowly- and declare Pakistan off limits for international shipping. That alone would ensure that 99% of all international shipping lines (the ones that carry majority of your trade) stop immediately and don't come close to Pakistan!
That ensures 2 things:
1.International Shipping lines themselves stop going to Pakistan
2. Pakistan's own merchant shipping lines who will defy the Indian blockade will not find a place to land bulk cargo! Because bulk cargo cannot be unloaded on beaches, they require major port infrastructure to be unloaded! And all three of Pakistan's ports come within Surface launched missile range of Indian mainland!
All this accomplished without a
single Indian Navy ship getting involved!
Do you understand the difference now. It is to Pakistan's misfortune that your enemy has not just dozens of
major ports across a coastline of thousands of kilometers but also a Navy and Airforce that makes India the singular nation in the entire Indian Ocean Region that does not depend on USN to ensure its Sea Lanes of Trade remain open.
