So, obviously it is time to retire the old YU symbol, since it no longer refers to anything that exists. SCG (fine for graphic resolutions, not so easy to pronounce in a pleasant way) is also gone. So it's off to the International Standards Organisation. For a three-letter symbol, Serbia had the choice of SER or SRB -- no big deal there, the choice seems to have been SRB, fine. But then, there was the choice of a two-letter symbol. ISO rejected the proposal that the new symbol be RS ("Republika Srbija," but their rules do not allow the form of government to be a part of the symbol, they say, which ought to call CH and UK into question, no?). They proposed as alternatives SP, SQ, SS, SW i SX. Not any one of these is especially appealing, but the Ministry of Foreign Affairs chose from among the options the symbol SS.
Is there any point at all in even beginning to set out the reasons why this was a bad decision?
