The history of human civilization in general has been one of force and savagery, gradually (and not monotonically) becoming more civilized. It's an interesting idea that a country (that is, the people living in a certain country) should have some kind of "original sin" for things that happened before they were born. Ask a German how they feel about that idea. Even so, there is nothing special about the United States in the respects that you mentioned. Learning about history is the antidote to that belief.
