“In the Korean War era, the UN was viewed differently than today. You cannot judge the actions of a preceding generation with the memes of the current one.”
I read an old American Legion magazine, probably about 1960, and it had an article about Americans fighting in the Korean War under the UN flag. That was just one of the things about the Korean War the writer was very critical of.
1960 isn't 1950. I'm not at all fond of the UN (I think the US should get out of it and require the relocation of UN headquarters to someplace like Geneva), but denying that the US troops fought under the UN flag is on the same level as destroying Confederate monuments.......it is history...stop trying to destroy it.
