Korean troops Leaving Irbil?

How did I miss this story yesterday (via Raed)? First Ukraine, then Italy, then Bulgaria, then the UK, now we hear that Korea may also be pulling (at least some) of its troops out of Iraq in the near future.

Can this be put in the context of President Roh's new 'Korea is the new Northeast Asia power balancer' line? Or is he just desperate to get the troops out of there, since they have now served their purpose of demonstrating loyalty to Bush?
