"Who cares (other than them) if South Korea is free and democratic or a despotic, totalitarian, dictatorship or radioactive?" This is one of the worst posts I've ever read.
So you're OK with nuking the Korean peninsula and murdering millions simply because you don't care? You are a contemptibly foolish dolt to suggest that the Korean people "mean(t) nothing to us". To the corner with you, hang your head in shame, and think about the children, the families killed, the land destroyed forever simply because you believe in economic cleansing. Trump would be fittingly proud of you.
