Hahahahahahahahaha. Sorry but your naivete is amusing.
Sure, I may have been 5 years old when I went through a [very short] civil war, but I still remember the news. Many soldiers didn't even know why they were being asked to shoot this or that. While in the barracks they were kept under strict radio silence from outside and most had no idea a civil war had started. They were just told to go there and shoot over there. They didn't know if they were shooting at their neighbors from back home, at somebody they hate, or what.[1]
Eventually news spread and the war got very very bloody as people who used to be comrades became personally involved in drinking the kool-aid. Luckily the bloody parts were removed from where I lived, but a lot of my classmates in elementary school were refugees.
Civil war ain't nothing to sneeze at. It is the worst type of war.
[1] There's a video from a private telling all of this to a news crew. Seeing it on TV is one of my earliest memories. It's in serbocroatian and I don't know if there's a version with English subtitles. -> https://www.facebook.com/zetraprojekt/videos/865414093588116...
