The U.S would be pretty clear-cut victors. The Korean War ended the way it did due to Chinese involvement.
Any war will pretty much be just like the Korean War, except the Chinese are more likely to launch an offensive rather than save them and Korea's military is hardly more advanced than it was back in 1951. There is literally no reason why the U.S would suffer, aside from Nork launching it's few nukes at it's allies to the South and the East.
