re: #660 Sergey Romanov

Sure, but rumors are gonna spread, defectors are gonna defect and so on.

But again, spread amongst whom?

Here is some literature of interest, regarding campaigns (little outdated, perhaps):

* Communism in Korea: The Movement (Vol. I), the Society (Vol. II) by Robert A. Scalapino; Chong Sik-Lee. Berkeley: University of California Press, 1972.
* Liquidation in North Korea by Kim Myong-sik: Institute for North Korea Studies, 1980.
