"A nuclear strike by either country could turn out to be a pyrrhic victory since, due to the close proximity of several cities on either side of the Indo-Pakistani border, the resulting fallout could easily be blown over the attacking country."

If they're willing to use nukes, then worry over fallout isn't going to cocern them too much. It's better than being at ground zero.

If the Third Indo-Paki War starts and goes atomic, I expect each side to use two A-bombs. At that point each side will recoil and ask for a suspension of hostilities. After prolonged negotiations, the war government of each will be replaced by a peace government and a truce will be signed. The side that went atomic first will have to pay some reparations.

The horror may have a benefit. The Iranians and the Arab states with A-bombs may see the non-benefit of this type of war and stick with the sponsorship of terror groups, rather than trying atomics.
