I happen to live next to one of the heads of NK, and even if there is a moderate wing they do not represent NK. The NK is an extremist fanatic group. They themselves disassociate themselves from any moderates who claim to be NK.
The moderate NK disassociate themselves from the fanatics, and claim that the fanatics do not represent NK.
Bottom line? There are two groups calling themselves NK, each deligitimizing the other.
