Please watch the PBS documentary, the Battle of Chosin. It is about 长津湖战役。
If you must fast forward, forward to about 1:29, and listen carefully on what the veteran was saying.
Even when the war is just, we must be careful not to glorify it too much. We must realize that both sides suffer during it and after it is over.
