What is your main problem with Pakistan ? That is you have to clearly define what are the aims and objectives of such a war? What do you to achieve.
Depends on the war. Everything likely cannot be achieved at once. There will have to be an initial war for PoJK. Then, either as part of that war, or another war (either conventional or sub-conventional like Russia's Donbass and Crimea campaign) - we must take back certain pieces of land like Hindu parts of Sindh, Sikh areas in W. Punjab, and strategic features like Akhnoor Dagger & Shakargarh Bulge.
Then a final, definitive war where we finally deliver the much discussed bifurcation coup de grace which permanently separates Sindh & Balochistan from Paki Punjab.
I'm in favor of fomenting a massive, unfixable insurgency in Pak's Pashtun Areas before fighting such a definitive war as well.
My long term goal is a disarmed, denuclearized, landlocked West Punjab which is permanently put in its place.
Absolutely. Not all of it. But PoJK, Eastern Sindh, slivers of West Punjab, Akhnoor Dagger and Shakargarh Bulge are all a must.
You want that Jihadi population of 22 Crores and ensure that Kejruddin or Asaduddin Owaisi is the perceptual Badshah of India?
No, once you see my stated vision; it should be clear I have no interests in taking on such a big population (not that I'd give them all the ability to vote anyways). Sindh and Balochistan must become independent countries which are friendly to India and bound by defense treaties.
Or you just want to kill as many as possible but to what effect.
I absolutely want to deliver a severe blow in terms of death + financial damage as well - along with a resultant psychological blow.
Can the same aims and objectives be achieved by less money, efforts and damages and by means other than War.
No. Other approaches can form part of the greater strategy; but the final solutions will require India to get into the ring and get its hands dirty - even if it's only to deliver a final death blow.
How to you assess such a war with the National aims of India.
India has punished Pakistan four times militarily. Did it solve our problem in any manner ?
Only because India always sucked at following through/capitalizing on gains. India made a habit of bungling its strategy, or even worse - losing wars it had already won at the negotiating table. India is paying the price for its lack of killer instinct - it's both ironic and tragicomical to use that as an argument against war.
So why do we have tanks ? They exist to deter Pakistan from taking any military adventure which they have proved they are very fond of.. The primary aim of all militaries world over is to prevent military Wars - so does IA.
Coming to the crux of my point; what the hell are all these tanks for? They're certainly not for deterrence - you don't need THIS many tanks to deter Pakistan, nor do you need another 400 new ones. It also isn't deterring them from carrying out their 3 decade old subconventional war anyways. Your tanks didn't stop the Parliament Attack, they haven't solved J&K, they couldn't stop 26/11, and they can't even prevent Uri, Pathankot and Pulwama.
So either use them - hence the exasperated suggestion to at least invade Pak after buying all this hardware - or stop buying new ones and pissing away money which is in short supply already. Because to be very honest, currently they're just sitting and rusting.
