Will the U.S. Require Permanent Peacekeeping Forces in Iraq and Afghanistan?

If the situation in Korea is any indication of what may happen in Iraq and Afghanistan, the U.S. may be forced to bear the burden of permanent peacekeeping forces in both countries. With an estimated 29,300 U.S. troops still in South Korea several decades after an armistice was never fully ratified, the possibility of needing permanent peacekeeping forces may be required to deter aggression. Hopefully this scenario will not play out but after recent events, it is going to be difficult removing all troops from Afghanistan and ultimately more ground troops will likely be redeployed in Iraq. If the Korean model proves accurate, combat missions may not be necessary in the long run but the burden of a rotating/permanent occupation cannot be ruled out.
