I voted that the war will remain limited to convetional weapons. At the moment, there is no actual war; but it might well escalate. The chances of any nation ever using nuclear weapons unless their back is to the wall is extremely limied. this in turn means that the chances of one nation forcing another, nuclear, nation into such a position is very slim. India might well be able, for example, to convetionally overwhelm Pakistan. India however will limit its tactical objectives so as to meet its main strategic objective, which is "no nuclear war".
As to rogue pakistani generals letting off odd nuclear weapons, the chances for this happening are so remote as to be negligible. nuclear devices, despite what one sees in James Bond films, are not set off like firecrackers. It is extremely difficult for such weapons to be used at anything but the national level.
