Ultimately Pak power is hardcapped by its level of governance. Pakistan is just a poor country with low HDI. India may be insufferable and overestimate itself, but when compared to Pakistan it's just better governed.
Sort of same thing as Ukraine, you can lose and shatter even whole 1st world, if the medium you rely on is just too weak. As such, limit input to to scale Pakistan can comfortably absorb. Otherwise results will be also Ukrainian.
I’d argue it’s better governed than India, with all its advantages in population, economy head start at independence its unlimited partnership with both the soviet union and the west, it has been largely ineffective in establishing a sphere of influence, and the main reason for this is Pakistan resistance.
