In Korea, the US Army destroyed both the North Korean Army and the Chinese "volunteers". The Chinese took over 400,000 killed and another 468,000 wounded. The North Koreans took 350,000 killed and another 303,000 wounded PLUS more than 300,000 missing in action and probably dead. Versus 54,246 Killed and 103,284 wounded. That's damned impressive. In Vietnam, the US Army never lost a major battle and drove the North Vietnamese in Paris to sign a humiliating peace treaty with the USA and South Vietnam. The fact that North Vietnam violated the treaty two years later has no bearing on the humiliating defeat they suffered.
