Honestly I get when regions are split to north and south but countries...
we know that in North they use Choson (Joseon)
and in South their use Hanguk when talking about their country
that's same way as Japanese use Nihon/Nippon
when you say Deutschland everyone knows which country we talk bout
would be cool to see growth of that Hanguk naming instead of SoKor
another even weirder one is
Sudan
and South Sudan
