Bhai Jan US is on the run from Afghanistan and you think they can sweep in and take out our nukes? For that to happen the US will have to do about 100-150 simultaneous SF operations aguanst highly secure pakistani bases. I don't think they have the capability to pull this off when they will be facing Pakistan army in all of these locations. Also, they would require complete air suppiriority to pull this off, I don't think they can ground the entire PAF in less than 24-48 hours. That will be our cue for counter attack on US basses everywhere in the region and any aircraft carrier in the Arabian Sea. Believe it or not, we have the kind of strength to decimate US bases in the Central Asia and Middle East.
Even if 10% nukes survive, it will be a failed mission. Even if all nukes are destroyed, we have the resources and knowledge to build them again.
And that's when I haven't taken into account the Chinese reposne to such an attack.
Using Afghanistan as an analogue is incredibly naive. Afghanistan does not have strategic areas and expensive assets to loose in a war.
Taliban is an ideological force that [doesn't] needs military bases to operate, expensive logistics to fuel its war-machine, needs to protect strategic areas, uses expensive weapons and its personnel do not wear a uniform. Taliban is an asymmetric ideological threat which cannot be eradicated unless every Afghan is dead and American politicians are not willing to order a genocide in Afghanistan for this purpose.
Persian Gulf War (1991),
Operation Praying Mantis and
Operation Opera are valid analogues for our situation.

US doesn't have shortage of equipment and other forms of resources; its military might is most resourceful and capable in the world. USAF, alone, packs lot of firepower and can conduct hundreds of sorties [simultaneously].
During the [first day] of
Operation Enduring Freedom, 100 aircraft and 50 cruise missiles struck different targets in Afghanistan. These type of assets are most useful against targets of high value.
USAF can wipe out PAF in a span of few hours. And US military bases in the Middle East are protected by state-of-the-art ABM systems (that actually work).
Stop living in the fool's paradise. Pakistan doesn't have an answer for every threat in the world.

The above being said, total war against a 'regional nuclear power' is not (advisable) unless that nation becomes a threat to the security of the entire world. Even if such a nation is successfully disarmed, their will be bloodshed and fireworks.
As for Pakistan, it should disclose its intentions about what it aims to achieve with its nuclear arm and decide a CAP for its nuclear arsenal. I don't see the benefit of building hundreds of nukes for a country like Pakistan due to its size, economic and geopolitical scenario; such a development would invite more unwanted attention and may also have unforeseen consequences.
