Please trust my words, firstly, Pakistan has no nukes deliverable by missiles, secondly there is no pen in Pakistan which can be used to sign the death warrant of 22 crore Pakistanis and finally there is no finger which will push the launch button. I have been proven right after we did Balakot.
All Pak Generals get huge amount of land after retirement in Punjab. Do you think they will let it become dry by fighting with India? What about their own existance and future? Long back I had written here that the best way to dismember Pakistan is to send in our IBGs into Pak Punjab and dismember them with strike Corps in Sindh. CSD is a very dangerous tactices. PA will be forced to commit its reserves very early which will not be able to shift their positions. If the reserves and strike Corps are committed in the begining of the war, they become easy meet in their build up areas. Taking out bridges and other obstacle clearances can confine them to a very small area to be taken out by arty & air power. Pak has nearly no Railways, they have no fuel and they have no heavy transporters. They had build up there narrative that India will forever live in the fear of their nukes. Modi has demolished that narrative. he has challenged them to come and fight within nuke umbralla and not at sub prime level. This is new India. Jo ghar main ghuss kar Marega.
There are several reasons why Pakee nuke threats are BS.
1) We can carry out an invasion during a certain time of the year w/ certain wind patterns to defeat nuclear fallout.
2) We can choose to attack along their rivers, they won't dare nuke that
3) Our troops/formations can hug theirs (and it anyhow won't take long for us to cut the distance - to the point where nukes become impossible/pointless)
4) They would never risk fallout/impact on Punjab
5) India & friends are always tracking nukes and would likely unleash massive pre-emptive strikes to take care of most of them ahead of time
6) I've also heard doubts about Pakistan's ability to effectively miniaturize nukes for tipping missiles, and their devices are apparently not well tested either
