They know what they need to know. The numbers are accurate. It is not easy to hide nukes or their manufacture.
The larger point is that no way will there be a war where more than a few nukes are used. Why?
For Pakistan to launch all 100+ nukes together, you will need a prep time of at least 3 months. So not gonna happen. Even assuming that Pakistan wants to launch a salvo attack of 10 nukes, it will still need a prep time of a week, nothing less. But say you manage to salvo 10 nukes before anyone figures it out, before Indian response can exceed the same number, the west will stop the war. From their perspective, objective of partition would be pretty much met by then.
Finally, nothing personal man. I only dignified a response since you are a think tank analyst, else I would not have bothered to reply. So I highlighted that fact first.
