US history is extensively documented. Nobody is claiming that there aren't long lists of terrible things done (and still doing, I might add). The factual nature of those claims isn't really open to challenge. It is often pointed out in real time as the decisions are made.

If 'acknowledge' literally means acknowledge then I doubt you'll struggle getting what you want. If 'acknowledge' means 'and then we have to follow my political recipe for what to do next' then it might be a struggle.
