Mike, the distance we are falling back is fairly insignificant as far as "giving us more time to mobilize", and won't make much of a difference as far as air power goes either.

What it WILL do is reduce the possibility that some incident short of an invasion along the DMZ will involve Americans, which could get quite ugly quite fast in view of the tensions right now. Some South Koreans fear that such a move could make the North Koreans MORE likely to cause incidents; others take a even more cynical view, and wonder if/fear that we are trying to disengage enough that we can make a deal with the North Koreans that may not have South Korean interests in mind.
