Islamabad cannot expect New Delhi would sit idle and suffer a nuclear strike without massive retaliation. So basically, if Pakistan goes for the nuclear trigger first, it commits suicide. If India goes for first-use, Pakistan still ceases to exist. It is a lose-lose proposition for Pakistan in every situation.
YOU ALL ARE STUPID.
IF YOU THINK THE INTERNATIONAL COMMUNITY IS GOING TO SIT IDLY BY WHILE 1 NATION ERASES 200 MILLION PEOPLE YOUR ALL STUPID IDIOTS.
The world powers are going to let Pakistan and India shoot at each other, kill a couple thousand soldiers, bomb some cities/ military bases, but in the end both nations know what crosses the Nuclear threshold.
Realism in International Politics says that Nations think about power, power = survival. No one is going to shoot them self in the foot.
India itself doesn't need 110 Nukes for Pakistan:
Islamabad+Rawalpindi = 1
Lahore = 1
Karachi = 1
Multan or Faisalabad = 1 or 2
--------------------------------------------
Pakistan = Destroyed
Dehli = 1
Mumbai = 1
Calcutta = 1
Bangalore = 1
Insert 3 other big Indian cities based on population
---------------------------------------------
India = Destroyed
Beijing = 1
Shanghai = 1
Guangzhou = 1
Insert 6 other big Chinese cities based on population
-----------------------------------------------
China = Damaged, Government decapitated.
