Leaving little gaps makes a big hole

I do not think that they should leave things out of their education simply because something went wrong or they are shamed of it. Yes i agree it is not something to be proud of for killing a bunch of innocent people or slaughtering PoWs, but i think that people should know somethings about what their country did. For example the bataan death march should be recorded in United States History textbooks. I think they should also cover more of the Vietnam war even though people look down on it. I think that they should look over ALL the history of a country because it will teach people that yes everyone makes mistakes and we are no different. It gets to a point where people are wondering what happens at that point in time. I can honestly say i know almost nothing about the Vietnam war and all i do know is basic things and what i learned from hearing horrifying stories, playing games, and watching war movies.
