1) Why in hell did he ever go back?
2) He is very lucky he was not charged as a war criminal.
He was lucky that the Nork’s didn’t “accidentally” lose him in one of their death camps.
He may well have played a cat and mouse game for years.. and finally got trapped. Fortunate for him, they didn’t exact a pound of flesh, rather from his pride.
3) Maybe he is still working... Note what the North Koreans accused him of.
"It claims he was an "adviser of the Kuwol Unit of the UN Korea 6th Partisan Regiment part of the Intelligence Bureau of the Far East Command" - an apparent reference to one of the special operations units acting against the North."
