seems like kapoora sleeping and dreaming of a nuclear war with pakistan and its limited ofcourse because in his dream he sees india attacking pakistan with nukes and when the retaliatory part of the dream comes his "havildar" will wake him up from the dream thus it would be a limited nuclear war between india and pakistan.
now the question arises, how would the "havildar" know when the pakistan retaliation part of the dream is about to start, i think kapoora might have told him that whenever i start shivering in the dream or i pee you should instantly wake me up, coz this is what happens to all those who see such wet dreams about attacking pakistan with nukes.
