I'd see it as being negative. Half a century of having some other nation guarding your border because you won't do it yourself? Yell yes, I'd be pissed at my government and the government of the troops. Thank you, time for you to go home.

And it is time we leave the Korean peninsula.

Leaving Korea now would be seen as an open door to invade by the North. War would immediately follow.

When I was in Korea in the late '80's there were still plenty of Koreans that would come up to an American and thank them for stopping the Communists. It was only in those years that the South Korean economy surged to the point where they could prevail over the north. The South Korean Army was plenty aggressive, but remember that the North Koreans have 1 million men under arms - a million!

The situation is somewhat more complex than you seem to understand.
