There lies the problem...
India will respond with massive nuclear retaliation if Indian troops are attacked with a sub-kiloton yield nuclear warhead inside Pakistan's territory...that is what you think...
We think,that it would be childish to respond to such an attack...and don't you even think for a second that India will remain unharmed in the final assault...nukes are designed to be used.
Coming to the topic...do you really think that there will be only one Nasr TEL present for the attacK?
Let me paint you a clearer picture...
We are talking about dozens of Nasr vehicles,approaching different launch areas and assisted by A-100 MBRLs...not to mention the dummies,which are a part of the strategy...designating and pin-pointing the specific vehicle which is constantly on the move is almost impossible...
One thing more...if a nuke can be mounted to a Nasr system...it can definitely be mounted on an Abdali or Ghaznavi system...Nasr is more of a message...
To Add some more points, Darky was so obsessed with his Retaliatory response, he forget to think, We should have to locate NASR FIRST.
Nasr is just 60 KM missile. So first thing came in to mind, in initial phase of Battle, Nasr will not be placed near border, but rather some where hidden in Sand made bunkers or away from the border, so that when OUR line of defense is breached, we retaliate back with NASR ONLY IN OUR LAND. which means NASR will not cross indian border and will remain in Pakistan and will hit all the rapidly moving divisions. Due to Shoot and Scoot ability and low fly path, which means, it is difficult to detect the nasr by the Rapidly Moving Indian Divisions as they don't have the radars with them to detect a very low flying missile hitting them
AND in initail phase of Battle, indians will be busy in locating our Other short and medium range ballistic missiles as well as Cruise missile sites, which will be immediate threat to them and as Haseeb pointed out NASR DECOYS will be used.
Third thing, NASR SYSTEM is AWAY from the battle field so, and indians UAV's which will be on look out for Nasr (In Pakistani Territories)will only see decoys if they are lucky to survive our MANPADS and Air Defences. In only ideal locations they will be able to locate Real NASR
Fourth THING which is most important. WHEN your SMerch Or PINAKA will fire their MBRLS, are you naive in your thinking that, you did not know Pakistan has Artillery finding Radars which can locate your artillery systems, and we will pay back in no time and our Respone will be as massive as yours will be Son....
A quote from Fatman-17 article on last page, which summarizes my whole Post
Its short range indicates that Pakistan may be forced to use Nasr in its own territory against attacking Indian forces. Hence Pakistan is more likely to be self-deterred against its use. Except the desert portion, India-Pakistan border is heavily populated. Therefore, Nasr is both counter-force and counter-value weapon.
