bjre should stop talking about South Korea as though he has a clue.
As a Korean American, I actually know the history.
United States and Russia partitioned Korea into the North and South.
North Korea launched a surprise invasion of the South in order to unify the country under communist rule. United States was positioned there, far too lightly, in order to honor a standing treaty with South Korea. United Stated responded to the invasion with a landing and eventually countering deep into North Korea. And then the Chinese intervened illegally, without a treaty to honor and without a single request for aid. Even Kim Sung Il, the North Korean dictator, specifically did not want Chinese interference. (He opted for Soviet support)
I'm a patient man, but this subject will make my blood boil. Bleat all the propaganda you want for your internal affairs, but you try and take my homeland into it and I'll humiliate you.
