During the closing ceremony of the 2018 Pyeongchang Winter Olympics, the presenters mentioned a rumour that was going around via social media (and the immediacy of such, natch) that North Korea was prepared to have talks with the South - with the US involved - re. Reumification.
Question: Was East Germany Communist? Especially when Trabants & Wartburgs started crossing the checkpoints in a certain Wall: before the rest of the West: as in Germans, started doing a Pink Floyd and tearing it down...?!
It's said that the DMZ is the most untouched ecological area for wildlife: for a good reason.
I see no reason why that shouldn't remain so; the mines etc laid by the regime that is a Cult of Personality will have been carefully mapped in their placement which resulted in said wildlife flourishing there.
And the only flag: as in the singular, being of a united, democratic Korea.
As the BBC presenters at said Winter Olympics also stated last week: that would be the legacy of Pyeongchang.
