Answer
I think that the US was very successful in containing communism in North Korea. I think that the making of the KDZ (Korean Demilitarized Zone) was right but I think that the US were wrong in underestimating the North Korean Army. The war lasted longer than what was needed because the US underestimated their opponent. I think that they should have not underestimated their opponent but on the most part, the US did pretty good.
