Heh, I don’t know if that was meant to be deliberately provocative or not. I’m of the position that losing Chinese loan words is a bad thing. But, I’m a bit confused as to what you mean in the Chinese realm.
Korea won’t be part of the Chinese realm — I’m not sure what you mean by this, Korea was never a part of China (unlike Vietnam) and Korea is one of the few places where you don’t have an ethnic Chinese places in East Asia (Japan is the other).
But, yes, there’s no way Korea will be part of the Chinese realm. Unification will only bring either (1) continued U.S. troops or (2) a unified and nuclear Korea... I don’t think the PRC would want either one ...
minus the four Han commanderies that never really controlled the peninsula. A liberal interpretation would put a quarter of the peninsula under “Han” Chinese control — some 2,000 years ago (Lolang gave out in 313 i believe)...
