Your potted "history" is so stunted it won't see lunchtime.
In modern history it was Japan which took over Korea. In early 1900's.
You might know Japan and China have had a fractious relationship for a while. No western governments were on the scene in those days. Prior to those days the Chinese had a few goes at subjugating the Koreans.
So this is "It was Western powers that split these countries into North and South waring factions." is just rubbish.
And this "The UN was and remains a puppet of the US so anything they decide is biased." is an insult to the UN, apart from also being news to the US and the other members of the Security Council, at the least.
