Well if this happens without a nuke going off we definitely need to get in there grab the nukes this time. We fucked that up back in the 90's.
Grab the nukes from the Ukraine? Russia supposedly secured them all over a decade ago and they've been compliant with their NPT requirements to both open inspections of the decommission to the IAEA, and abide by the USA deal to buy the fissionable cores.
Or do you mean grab the nukes from Russia? That wouldn't work, and there is no need, Russia is compliant with the NPT.
