My colleague tells me that the speech Ambassador Kim delivered on April 7 was featured on one of the lead stories on that evening’s newscast from KBS, the leading Korean network. You can see the video here. (Click on either “300K” or “56K.” Might only work with Internet Explorer.) The quote from the speech is at about 0:48.
For the full speech, click here (RealPlayer required) and skip forward to 1:09:28 and hang on for just over 16 minutes of thrills, chills and awkward mispronunciations.
