This is rather a old documentary from National Geographic. But I found it interested and was amazed how north koreans were so greatful to their leader for getting a sight but not to Dr. Ruit. I was doing search on You tube on North Korea and started watch this. When DR Ruits name appeared I was so proud..............It is interesting but need some patience. It is 45min long documentary. <object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/mxLBy..."></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/mxLBy..." type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>
