There are some bad apples who rose through ranks during Kim Dae-jung Roh Moo-hyun governments. They did so by kissing the two guys' ass. In time, they can be agents of influence and could go one step further. Into the deep end.

The other possibility is that NK moles in gov uncovered major skeletons in his closet, and threatened him to cooperate with them or else. This is a more possible scenario,

Possibly... but I would be more worried about what the KCIA would do to me if I turned traitor and got caught than I would be of any skeleton in my closet.

Maybe the KCIA has been toned down a bit in recent years, but they had a fearsome reputation when I was in the American Navy.
