I was able to more clearly understand about the civil war in the United States after I watched this documentary. Although any war should be avoided, this war had a good result because of the emancipation of the slaves. In addition, I was much more empathetic while watching this documentary, as Koreans also had undergone the "Korean War," which was very similar to the American civil war. [Very good, Heidi, but next time put things you want corrected into the "Notebook" area of italki so the native speakers can use the editing tools available there but not here in the "Answers" area, okay?]
