alt Hacker News> Native Americans had relatively benign relationships with the settlers, while the latter were weak
Translation: Native Americans were nice to the European settlers, until the European settlers were in a position to murder and expel in the Native Americans. The genocide against the Native Americans happened both before and after the founding of the United States, which casts serious doubt on a claim that the US has a "moral" mission.

Not sure where this math came from. Slavery was legal in all 13 colonies at the time of the revolutionary war. It wasn't until later, and in some cases much later, that the so-called "free states" actually freed slaves.
The US had a highly moral mission at the time of its founding; but that moral platform differs significantly from our own today. The adjective "moral" does not mean "in good standing with what I believe is proper morality", it means "of or relating to principles of right and wrong in behavior".
I do not believe that the majority of Americans today believe that there is any "moral" purpose for the American government to exist. The left wing sees the US as a fundamentally illegitimate country founded by the dual sins of slavery and genocide that should be improved by dismantling its own myth structure and importing as many foreign cultures as possible to supplant whatever came before. The right wing is only interested in the existence of American hegemony insofar as it can use it to crush its cultural enemies or enrich itself, and is happy to violate by theft or violence any American principle in name or in spirit so long as there's good short term gain.
Neither is thinking of the Nation as an aesthetic and moral project to advance the state of mankind under God, or even Science, or Human Rights, which was how its founders explicitly thought and wrote about it.
