On Rahm-ie, please re-read “professional slanderer” as “professional blackmailer”. Think that’s a better fit. Thanx.
and no, contrary to what you might think, it’s not that the government in SOuth Korea is full of Communist sympatheziers (although there are); it’s basically that South Korea doesn’t want to pay for unification (and put it off until it becomes even more expensive). Hence, the entire denial thing.
