Let satisfy yourself when I and foreigner friends roll on the floor laughing.The US lost ground to China. We didn't lose ground, we gained ground. Strategic victory for us. The US was at the Yalu river before we entered the war, North Korea was under full American control. At the end of the war, the US was driven back to South Korea and North Korea was liberated by us from American rule.
No other country has made a complete mockery of the US military like we did in the Korean War. That's why the US never talks about that war, too humiliating for them. They want to pretend they have never lost a war to keep the ignorant population brainwashed with the propaganda mouthpieces from the American regime.
The US had far superior technology and weapons and over 20 nations helping them against a poorly armed Chinese volunteer army. Yet we still managed to make a technologically superior military with a massive military budget to retreat in the most humiliating way and achieved strategic victory.
We are the only country that have defeated the United States military in war.
