Wrong!200+ nukes delivered at 200 strategically identified sites will make sure India eats dirt for the next 1000 years or so.
a. Pakistan does not have 200 nukes.
b. Pakistan does not have enough launchers.
c. Pakistan nukes are not having enough yield.
d. Nuke explosions disperse fallout. Look at hiroshima and nagasaki.
Most of Chinese live near eastern coast of China, far from India, Pakistan and their drama.Yes obviously China would love 400+ nukes exchange right at its borders.
How come? And Ghauri is useless for retaliation. Its liquid fueled and takes too long to get it ready. Your reliable launcher is solid fueled Shaheen MRBM which you have less than 50. Assuming all survive first strike and are not taken out by Indian attacks.75 is a decent estimate based off 2 x "Fewer than 50."
