Pakistani Navy becoming an extension of PLAN and CCP bankrolling them for free must be read with pinch of salt.
PLAN juxtapose to it's direct competitors and the possibility of Quad becoming a reality with better port networking, has become more vulnerable and outnumbered. They would rather spend their money on themselves than dole it out on Pakistan who can be easily muzzled by the USA at the right opportunity.
Secondly, you can not simply throw ships into the ocean and start expecting them to cater desired doctrine. This where the devil of the detail is. India with it's clout among democracies and the civilized world can try denying them the access of the latest technology.
Quixotic Pakistan being driven by it's Indian paranoia and Chinese making the best out of it; India must use the same paranoia to its advantage and go full throttle on 3 pronged strategies.
Increase threat perception. (Hot tailing, small skirmishes, demonstrating amphibious attack capabilities, etc.)
Technology denial, technology obsolescence and sanctions. (Offer better deals, JV’s to their possible vendors and use their poor human rights record, terrorism and atrocity literature etc.)
3rd point which everyone is prescribing and seems very obvious to increase technological edge and build overwhelming capabilities. TBH our capability building must be organic where we absorb the technology to our maximum benefit and work judiciously with the funds.
What we want to do with Pakistan will be done to us by China vis a vis arms race.
Therefore, my third proposition will be to invest heavily into intelligence gathering, espionage, sabotage to instrument delays to their plans.
