There is no way Iran gets Nuclear umbrella from Pakistan in current situation.
I think it’s likely a mix of 1,4,5,6.
Theoretically, if credible intelligence was unearthed of an imminent nuclear strike by Israel or America, Pakistan or another party could fly one of their own tactical nukes into Iran for a demonstration detonation test in the desert.
Ideally the blast would be done underground so that no analysis of the fallout material could be done by outside parties to unearth the true province of the warhead. And such a demonstration should immediately cancel any ISUS nuclear strike ideas as immediately suicidal.
Obviously massive risk for the country donating the nuke inherent in sending a nuke into an active war zone with minimal ability to safeguard it from attack or seizure by the Iranians. But it is a viable way to derail any ISUS nuclear strike plans if anyone was brave enough to risk it.
