I'm not foolish enough to claim we're perfect - far from it, especially when it comes to restitution towards former colonies and looted art from there - but at least we recognized how and where we fucked up, and we're teaching our children about that in school. We don't skip over the horrors of WW1, we don't skip over WW2 and what led up to it, we don't skip over the various genocides committed on European soil. We acknowledge and own the stuff that our ancestors did.
In contrast, as I mentioned, more and more American schools outright ban books and teaching about its problematic past, or (like MKULTRA) it isn't taught about at all.
