You will be the first one to fire a nuclear weapon..so you tell me.
We will just be responding to it, as per our already declared nuclear doctrine.
You will be the first one to cross the borders of a nuclear power maybe to the point of forcing it to use the unspeakable , so its your call here , Pakistan will resort to using nuclear weapons only when hypothetically its major towns and cities are captured / its fighting capability is severely limited and most importantly the sovereignty and the very existence of the country is in danger , not before , though whatever happens or in what order it happens or has the more probability of happening is only a matter of conjecture and can be closely related to Murphy's Law ... It certainly isn't like that Pakistan will use a tactical nuke when the first Indian soldier cross the border , we can hold on and defend for weeks , that theory by your Internet warriors is hilarious to say the least , may I just suggest that they learn about the conventional fighting strength of the seventh largest army in the world ?
Rational answer to your above is..
If Pakistan decides on a Nuclear strike in a war, for its own sake, it will certainly not foolish enough to just deploy tactical nuke on small military target/s.
Not necessarily , no ... The armed forces of Pakistan hope to deter the aggressor from fighting a war in the first place by deploying such systems , they are encouraged by the success of that strategy almost three times now ... Tactical nuclear weapons can be used to warn the invaders that the nuclear thresholds have been crossed/are in the process of being crossed /have high probability of being crossed now and further action will get both countries to a point of no return then and would certainly put the aggressors in a dilemma whether to continue the misadventure risking the lives of a billion or to retreat back getting a few IBG's neutralized at the cost of image ? For those wondering whether Pakistan would nuke its own territory , it actually only makes it case stronger to use it on invaders on its very own soil to defend the motherland and knowing that they are most likely to be used in the unpopulated desert lands of Thar/Cholistan or Rajasthan , it is not that big a price to pay to safeguard the existence of the country ... The upper areas of Punjab and Gilgit-Balitistan/Azad Kashmir are ill suited for heavy mechanized offenses ... Indeed , Pakistan isn't foolish enough to use a TNW and then wait and watch for the next Indian move , and as soon as the first Tactical nukes is dropped , the SPD will go on high alert as usual and start deploying the rest of the strategic ones if not already then , but it certainly wont be the end of the game , that , sir will depend on the adversary's very next move ... The essence of the post is that " Pakistan owing to its geographic disadvantage of lacking strategic depth and limited offensive fighting capability has higher probability of getting its nuclear thresholds being crossed than adversary's " ...
Because such a scenario gives India an opportunity to carry preemptive conventional as well nuclear strike to take out remainder of it nuclear weapons.Owing to the fact, that it has relatively limited land area for dispersal of its weapons and absence of nuclear triad.. gives it very limited second strike abilities.Its land based mobile launchers remain vulnerable to the enemy strikes.
The same goes for Pakistan to take out as many launch sites as possible , the conventional war can go unhindered from here too , but again you are talking of crossing a threshold by attacking the nuclear facilities which can be actually anywhere , the results of which wont be pleasant , make it "use em or lose em" for the Pakistanis at GHQ and they will certainly make it worth your while for the catastrophic misadventure ...
Pakistan is the 37th largest country of the world talking in terms of area , it has more areas than you are thinking right now to disperse nuclear weapons , we aren't the Maldives or the Coco Islands ... Pakistani nuclear triad will be completed in the near future if the reports are to be believed and the inauguration of Naval command at the SPD be considered seriously ... Western reports have repeatedly mentioned that the Pakistan has addressed the issues of survivability in a possible nuclear conflict already has a robust second strike capability in place ...
On top of that, Indian nuclear doctrine of Massive punitive retaliation in case of nuclear strike on India or Indian forces(irrespective of the size of the weapon deployed by Pakistan)..gives Pakistan..very little wiggle room in this department.
If Pakistan were to deploy Nukes it will all out strike and certainly be a measure of last resort.
Back to Square One , you are ... Remember what I said about gambling with the lives of billions for a few invading IBG's ? It makes no sense to me but since when are wars fought on rationality ?
Not really ,there's much more to that strategy than you have studied and understood ...
