Let's not commit the same error we did by liberating BD only to have 2 inimical neighbors on both flanks with China breathing down our necks making it a 3rd flank.
Let Pakistan implode on it's own . As it is they're doing a splendid job. Hope it self accelerates.On it's own neither Balochistan not Sind not KPK can liberate itself. If we try & exercise our strength in liberating Balochistan assuming we get into a war with Pakistan, we risk alienating Iran as they're facing a Baloch insurgency too in the Sistan Balochistan province. Our aim ought to be restricted to retaking PoJ&K + Chitral.
If need be, for strategic purposes , to straighten the border & contiguity We can extend it to capturing the Shakarharh bulge in Pakistani Punjab, the whole of Tharpakar & Umerkot districts of Sindh & parts of Mirpur Khas, Badin, Sanghar & Khairpur contiguous to Umerkot & Tharpakar.
We ought to fan an insurgency in Sindh, Balochistan & KPK only to the extent that it remains a LIC & completely ties down the PA with associated para militaries, suck their finances dry & exhaust them just like they bled us in Punjab & Kashmir.
