from what i saw on the news there was alot of POWs captured in korea that defected to the communist side. and were moved to the ussr after. i saw an interview with one who was living in poland. but that was in the early 80s. and at the time his and the rest of the defectors U.S.A. rights were revoked and were not allowed back in the country, territory, posession, P.R., embassy, and military base or post. not even to attend a family funeral.
