Resolves to N/A if a Russian nuclear weapon doesn't strike Ukrainian territory in 2022. 

 Russian nuclear weapon strikes Ukraine AND targets somewhere with a population of >30K, with the primary intent being murdering the inhabitants.

If several nuclear weapons are launched simultaneously (within 1hr), it resolves to YES if any of them do target a major population centre.

Resolves to NO if a Russian nuclear weapon strikes Ukraine, but doesn't target a major population centre.  

Resolves to NO even if later on in 2022 Russia does target a major population centre, as long as the original strike didn't. 

Resolves NO if the nuclear weapon strikes somewhere close to a population centre, but isn't primarily targeting that population. Ex: attacking an abandoned military outpost close to Kyiv.
