Who else on the planet would have the effective power to possibly even think about who should and shouldn't have them, while plausibly being able to do anything about it?
Then you're in no position to throw rocks. The US is currently humiliating itself on the world stage in a fashion that makes Brexit look positively sage in comparison.
Given how the situations w.r.t Ukraine & Iran escalated, the US is the only country that has specifically and publicly demonstrated it's inability on both counts.
We can't give Ukraine their nukes back because they were decommissioned (and they were rotting at the time), but there'd be no nation more deserving.
Corollary: no individual nation is able to shoulder such responsibilities.
