I suggest that you go thru in detail the topography of POJK and read a bit about mountain warfare
Of course there are many challenges but don't you think, crossing the pir panjal entering the valley and fighting with the SF on Indian territory is something shouldn't happen? India dominates many parts of the Neelum but doesn't utilize it.
It has become a mischievous circle and it won't be a short term skirmish any more. It's a long one.
But the most important requirement is logistics for holding operations. And between India and Pakistan, whom do you think has better logistics?
India can move logistics swiftly already proven last year when thousands of paramilitary forces were air lifted across India and within hours deployed. This gave shock to not just Pakistanis but Chinese and the whole world. Thats what IAF has C17s ,Il76 and C130 plus new orders for 62 airbus C295 for various roles.
But only when the polity-bureau decides. If the sarathi of a Chariot is nalayak, the commander will crash even if his Chariot holds 21 horses.
India if wants, it can any time climb on Haji Pir it would hardly take max 4 days, but the order will never come. Because Pakistan had made sure through its proxy war that , SF and RR remains in the valley.
They are using diversion tactic.
They directly told their parliament that they don't want their adversaries to know the accurate number of KIA in PA. Have you ever wondered why PA always claims India is targeting civilians while IA always publicly claims it's martyrs?
This happens when you don't have sources in POJK giving out info, although it hardly matters, cultivating sources to gain such information is a waste of time. But still, for long term skirmish India will need to do more hard work on making Mukti Vahani in POJK.
