Nuke it from orbit and blacklist it
Assume thenthat the year is 1945, andbut we had the internet and Stack Exchange. Someone might ask: "Is a nuke allowed under the Hague Convention?" and tag it current events. This question would, by far, not be current in 2025.
SameThe same thing applies to any questionsquestion some time after the event. it's exactly why we got, after a few weeks a dedicated covid-19 tag. So the tag serves no purpose, I call exterminatus and blacklist.
