Browsing the internet post-class today, I found an article (thanks, Wikipedia) that discussed repatriation of Koreans from Japan after the Korean War, with the majority of people returning between 1960 and 1961. I was primarily interested in the Japanese wives of Korean citizens, who, though moving to Korea with their husbands, were promised by the North Korean government the ability to visit their families in Japan every few years. Reality has proven this not to be an option; in fact, most women have not been able to keep up contact with relatives in Japan.
This reminded me of post-World War II Soviet Union, wherein Moscow sent Welcome Home letters to Russian ex-patriates living in France. A good deal of Russians returned, bringing their French families, only to be jailed or executed upon arrival. The lucky ones were sent to live and work in remote cities in Russia, and their French partners unable to keep contact with friends and family back in Western Europe. (If you're interested, there is a very melodramatic movie that came out in the late 90's about the topic.)
I'm curious as to just how many countries have adopted this post-conflict policy: to encourage not only ex-patriates, but their foreign families, to return home -- only to keep them locked up. A sad sort of homecoming, it seems.
