You obviously didn't read my orignal post , seems like you are too blinded by self confidence of Indian 27th February type. I was speaking about Pakistani weapons engineers incorporating this for countermeasures into anti-Ballistic missiles and for targetting, that's what I heard, my sources wouldn't tell me any more. I have no way of authenticating the truthfullness of this just like I had no way of proving after being told Pakistan possessing nukes a decade before Pakistan tested them. I would like to add however that this would be a natural evolution of having multiwarhead ballistic missiles. If you have many eggs in one basket you want to protect the basket!
