I think the U.S. should close our base on the DMZ, evacuate all of the Korean Christians, and let the rest of them annihilate each other.
There's a yahoo article on the same topic and they recommended evacuation all NK's hottie women first.
After all, there's a shortage of brides in South Korea's rural areas. Importing some NK brides would stop SK from importing women from Vietnam and the Philipines. /snicker/sarc
