Since Moon's takeover the peninsula has become less like divided Germany than ever. The ROK has abandoned the competition for legitimacy, instead ceding the North's superiority on nationalist grounds while reaffirming that these matter more than liberal democratic ones. I'm not sure a league will ever come about, but if it does, it will hitch a proudly radical nationalist state to an unloved, moderate-nationalist one too shamefaced to celebrate its own founding. If the South is already unwilling to criticize the North, or to renew a commitment to its own constitutional values, it's hardly likely to mount a strong defense of human rights later on.
