The russia and china tags are used on 63 questions and 20 questions respectively. I've asked two questions that seem to be about the US space program and government positions, so I've created united-states for them.
Was this a reasonable extrapolation and thing to do? Do country tags have a clear role in Space Exploration SE, and are we using them for the purpose for which they are designed?
I don't see any problem myself, but since I've just created one, I wanted to double check that this was reasonable. There is a possibility that the Russia tag was created because of the historical changes in the space program from the Soviet era to current times, and that the China tag was created simply because it was thought that people would not start typing CNSA when asking about the Chinese space program.
