In South Korea we have enabled a perpetual adolescent who constantly whines about US soldiers. Every car accident involving a US soldier is front page news. It is ridiculous.
We need the troops elsewhere. Plus the tripwire strategy is limiting our options. Let the South Korean forces be the trip wire. The South Koreans can attrite the North Korean forces before we decide to intevene.
============================================
Hey genius, ROKs are the "trip-wire" and have been for years. US troops are further south than nearly half the civilian population so wtf are you yammering about?
