By leading our allies instead of being led by them. Iran is next door, and very insecure of KSA influence in Pakistan. Both KSA and Iran want to make a battlefield for their war inside Pakistan.
The issue with your plan is that Pakistan has no objectives to achieve in the desert. Instead of throwing 6 divisions in the desert, they could be more useful in Kashmir which is the main issue of every war since 1947. You could have proposed to make FCNA a corps HQ. Defending the desert is easier, the strategic value of desert is very less even if Indian Army ventures into it. Nasr missile was also made keeping this proposition in mind to be used inside Pakistan turf.
The nuclear umbrella didnt prevent Feb 2019, so Bhutto thought of saving grace after fall of Dhaka to eat grass but make nuclear weapons since it was PPP who didnt want to give the seat to East Pakistan. If East Pakistan was with us right now, then an atom bomb was authentic since Pakistan would have used it had Indian forces entered East Pakistan in a war and Dhaka was going to fall. Now the nuclear weapons save Pakistan from being cut into half from Sindh or AJK.
My post about combat aviation brigade is related to current circumstances but its helpful in future conflicts too and Pakistan lacks such a formation. Baluchistan is massive and ground forces are being attacked especially when posts are remotely scattered. A QRF of helicopter formations is needed to be able to reach the incident of affected zone with in minutes to provide fire power, reinforcements and medical evac to hospitals.
Outside Pakistan, the main issue is movement from Afghanistan which is interfering in Pakistan. Putting boots on the ground inside Afghanistan through a ground force is out of the question. An air mobile force backed by PAF can conduct missions and reach back with in no time after mission is completed. Pakistan doesnt need to capture territory in Afghanistan, just targets, their handlers, their safe havens need to be taken out. Fly in, conduct mission, fly out.
Turkey doesn't depend upon any other country to complete its military objectives. Pakistan on the other hand starts looking towards China or KSA or USA for weapons, support and funding. This has to stop. Kashmir issue and the Baluchistan COIN war is not KSA's headache. For money, how many and which conditions of KSA will Pakistan satisfy ? There is already another country with billions of investment sitting inside Pakistan - China. Then Afghanistan and Iran backed by India want their influence exerted through malicious channels. India doesn't want Pakistan to breathe either way.
Pakistan must work with China and nobody else, to first secure Baluchistan from Indian, Afghanistani and Iranian interference.
