But previously you wrote:

So *YOU* are saying that Norway is entitled to have full history but it
doesn't have to be accurate. So Germany's pre-1970 history *is* fine for
Norway.

So you need to find a different reason for saying that ISO 3166 is
important.

How about "places with the same time since 1970"? That's objective and
non-political.
