These aren't intended as plugs but I just finished reading
"The Reluctant Communist - My Desertion, Court Martial, and Forty-Year Imprisonment in North Korea" by Charles Robert Jenkins, and watching
"Crossing the Line" which tells the story of James Joseph Dresnok, and found both stories very interesting.
For those of you who don't know, Jenkins and Dresnok were two of the four US soldiers who deserted their units and crossed over the DMZ to North Korea in the 1960s. The other two soldiers who defected, Larry Allen Abshier and Jerry Wayne Parrish, died in North Korea in 1983 and 1998, respectively.
In 1980, Jenkins married a Japanese abductee, who was allowed to return to Japan in 2002 (she was abducted and taken to North Korea in 1978). He eventually joined her in Japan in late 2004, after turning himself into US military authorities and serving a short jail sentence for his desertion. Dresnok still lives happily (according to him) in North Korea.
Since they were together in the same boat for nearly forty years, one might think Jenkins and Dresnok would have become very close friends during that time but that apparently wasn't the case. The accounts both men tell of some of their experiences and time together in the DPRK, differ quite a bit.
