End up like one of those 'Manchurian Candidate' soldiers?... wandering around confused, going, 'down with freedom, down with food, hooray for the Apocalypse Now type situation the world has allowed for 60 years in North Korea, Dear Leader found my g-spot...'.
When I went to the DMZ there were still loud speakers set up on the North side of the line. Over the wind on a cold winter's day you could hear the voice of a North Korean propogandist suggesting to anyone who would listen that they come over and join the communist utopia taking place on his side of the fence.
