The South Koreans really don’t need us there anymore. I think that their fairly impressive military can defeat these nutritionally-deprived zombies if it came down to it. That is... if the South Koreans have gotten too soft in the intervening 20 years or so since I last trained with them.

Nope. They were ready, willing, and able to defend their country when I was there 10 years ago. Considerable upgrades to the Command and Control systems while I was there.
