according to India NFU policy,once it is attacked by nuclear,weather on it soil or other,weather high yield or low,it will reciprocate disproportionately.
Now the question is why Pakistan just want to use its nukes on some battle groups when they know that much bigger will be coming from India back,so is it not better to target Indian cities than those units.
Now if that is the issue,will Pakistan use the nukes against Indian cities as like India assume it will be preposterousness of Pakistan to use nukes against such small level conflict.
In either case what is the strategic benefit,only answer this if u carefully understand this,I dont need booster doses of nationalism.
