Changjin

Here's M.A.S.H. from the other side. h/t Hanania.

Franklin D. Roosevelt's State-Department and McEachran's protégés in Churchill's government had, not long before, "Lost China" - which, from their traitorous perspective, meant they'd won China: for Stalin. Stalin and his Chinese catspaw then swarmed into Korea. The United Nations swarmed right back again, running the Stalinists up to the Yalu. The lake Changjin (also called Chosin Reservoir) is in Hamgyŏngnamdo: north of the peninsula on the eastern Pacific shore.

The Chinese movie, which drained US$201 million, deals with a battle at Changjin. There weren't any Koreans here - which the movie acknowledges. (The "Forgotten War", as noted in the article, and for that matter by Clint Eastwood in Gran Torino, is forgotten by Americans: because the Americans who fought there don't like to think too hard on what they had done to the Koreans... and to the peoples further north.) This allows the Chinese filmmakers to run a straight fight between newly-Stalinist China and the US.

So, Stalin and his stooges, like Mao-now-Chairman, sent millions of dubiously-Communist Chinese into this dubiously-Chinese and also dubiously-Korean northeastern province, without really equipping them; and - somehow - beat the United Nations. An underdog story, I'll grant.

The filmmakers found whitebois to play the Americans - in China. They couldn't hire from overseas easily due to the virus from that Chinese lab (assisted by Americans, we must allow).

I will also grant it is difficult to see who the good guys were. As noted, even in America they'd rather forget it all happened.
