"City-upon-a-hill" is marketing and has never been grounded in fact. It’s hubris and arrogance. The US is viewed as that place if you get on the wrong side of, it will bomb you or replace your government through coercion. It outspends every country on "defense" to ensure this.
History is littered with plenty of examples where the US favored a more authoritarian or "evil" government over less, sometimes even installing them. Arab Spring is a recent example where you saw governments replaced with the US' help, while leaving some notable monarchies alone.
In reality, the US employs its foreign policy for its own interests. It’s always been like that.
