Even though I was in the AF, I spent some time on a boat in the Sea of Japan staring at N Korea. They had junk then and I'm sure if I read a Jane's Weekly, they wouldn't have improved a whole hell of a lot.
In any event, 30k troops costs a hell of a lot of money. Especially when you figure we've been there for decades. I'm sure S Korea can make their own symbolic gestures and do it on their own dime.
Same goes for Japan if the North decides they want to test the waters.
