The whole point of writing that scenario was to simply illustrate that India by itself is significant military power, and that maritime geography complicates victory over it a lot. It also illustrated(on a particular example), why PLAN is developing in a particular direction, and which problems it solves by doing that.
Why? Well, because this forum recently really got deep into India bashing mode. Which is annoying, - it's supposed to be about discussions, not another theater of war b/n netizens.
Adding 3rd countries beyond mentioning them on a basic level is simply too difficult and time-consuming. Even then, it's an interesting example in that it nicely illustrates two simple facts: one is that Pakistan is incredibly powerful asset in such a war, - even when it's on the other side of the Indian ocean. Another one is that there is yet another, purely naval reason why India is afraid of being surrounded.
It may seem illogical for a nation of Indian geography - but the fact is, it is vulnerable.
This is also perhaps the reason why they're quite nervous about this particular aspect of Sino-Pakistani cooperation.
Fair enough. I've also pointed out the strategic problem with Malacca Straits, but as I suggested, it doesn't belong on this thread because that is a target for a hypothetical US Coalition, not India alone. It's also an "all-in" move which will trigger WWIII. China is well aware of this and it is a core motivation for its BRI/CPEC alternative routes. China is also aware of the potential annoyance the Indian Navy can be if it is part of a US coalition, and this is a reason for the Air-Land threat that China is concentrating against India, in its new Western Theater Command, all along India's border. These are all important variables. And we can only ignore variables to simplify a model when the results approximate reality.
