Pakistan will certainly use nukes rather than accept a battlefield defeat from India

Pak nuke delivery is compromised by their proximity to their enemy. Takes time to load and aim. Ordinarily not a problem but both the US and India are less than 7 minutes from target. If the missiles are "setup" they'll be gone before they can be launched.

I'm assuming not all the nukes are on missiles. If they're delivered via plane they could be dispersed. Also, I'm reminded of the US Air Force's inability to prevent scud launches in the Gulf War. Pakistan has better capability than Iraq did and if they can tip these mobile missiles with nukes then the Indians can't be certain of taking them all out in one strike.
