We should have never gotten involved in Korea. It was the UN sticking its nose into it and the U.S. bearing the brunt of the costs and military.
If the commies would have overrun it, who cares? They overran South Vietnam but look what has happen, as it happens with all communist or socialist nations.
They turn to capitalism to sustain itself!
So right now Korea would be a unified peninsula with a free market economy. Sure they would maybe have the rulers with the communist mindset, but at least the people of NK wouldn't be starving or locked in brutal labor camps.
“Anyone else come to the sudden realization of how our political class have completely failed us, prior to Trump?”
Yes, see my post #26! They have ALL failed us.
“So right now Korea would be a unified peninsula....”
China would have annexed and occupied the Korean Peninsula decades ago.
