If this is the case, the UN is really just a flag of convenience. The UN passes a resolution and writes a nice document announcing that the fighting in Korea is separate from the fighting in rest of the Far East and Europe. This done, the UN recognizes the US chain of command in the ROK. Countries like New Zealand that may have some issues with fighting under US command are given a legal tonic to soothe the stomachs of the voting populace. A New Zealand brigade goes to the ROK, and everybody is happy. Until the nukes start flying.
