Now, here's the same story about a division's worth of South Korean troops possibly on the table for Iraq. The LAT puts more emphasis on "special forces", by which they seem to mean burly civil affairs/COIN specialists rather than snake-eaters, than the Korean reports, which seemed to suggest groundpounders.
The article also contains suggestions that it would be tied to an "understanding" that the US would bend on negotiations over the North Korean situation. The source actually says "there isn't a quid pro quo". Whenever somebody says there isn't a quid pro quo, you can be damn sure there is, indeed, a quid pro quo in the offing. Meh. Sounds like a bad idea to me. The South Koreans have been developing a weakened sense of self preservation in the last ten years or so.
