What is your recommendation concerning the exposure of our troops along the DMZ? Should they be pulled back out of the range of artillery in the initial onslaught? Should they be withdrawn from the peninsular altogether? Should they be left in place as a necessary tripwire?
What about the South Koreans, are they going to pay their own way, ensure their own defense, contribute to the general coalition that should be built to contain China?
I am not sure how the cost-sharing deal would work out.
One complicating factor is that U.S. put leash on S. Korea's ballistic missile and nuclear program. If S. Korea is asked to pay the full expense, they probably want those restriction to be lifted. Especially ballistic missile program. Currently their ballistic missile range is capped at 800km, IIRC.
