First point is an ad hominem, so I'll ignore it.
Secondly, Colon v US Department of State specifically refers to citizens who renounce their citizenship whilst still wanting to have citizenship in a US territory, the person in question wanted to remain a resident of Puerto Rico because he believed it should be a sovereign nation, but the government said he could not do that. Worcester v. Georgia (1832) states that just because an Indian territories are bound to the federal government, it means they are not bound to state laws and are still considered "sovereign." Although the US did pass the Indian Citizenship Act that makes all people born on reservations citizens, that doesn't necessarily mean that someone who renounces their citizenship but is still a part of the tribe couldn't still live in their borders. It's a grey area, but I think it passes. Even then, the point I was trying to make was that it seemed hypocritical that you would not consider yourself an American, hate the Americans as a whole, yet still engage in the privileges awarded to its citizens, like having your cake and eating it, too.
Thirdly, if you set up a moral standard no one can subscribe to, what is the point of the moral standard? If you hold everyone, or even just one nation, to an absurdly high moral standard that no nation can ever hope to meet, then you've essentially thrown in the flag. International relations are all about power dynamics between countries, where nations will try to negotiate terms that only seeks to benefit themselves in the long term, either through trade, diplomacy, or, worse of all, war, each country ultimately is concerned for itself and what will allow for its own prosperity, or to impose certain universal standards in order to prevent actions that are deemed to be crimes against human rights that do not benefit anyone because of Mutually Assured Destruction as a principal.
A nation cannot plow through other nations within the modern geo-political landscape because of Nuclear Weapons, along with things like NATO assuring that any aspiring empires will be quickly squashed as they try to invade and conqueror and more powerful nations like the US, Russia, Britain, etc. all join forces to stop their attempts to change the power dynamic. It was directly set up so something like Hitler invading Poland could never happen again, as all the people allied to the most powerful forces within the UN would put a stop to it.
As for your last note on my last note:
My argument was not that the Europeans did nothing wrong to the indigenous peoples, or that there were not war crimes and unethical processes committed by people against the American Indians. (I named a bunch, especially with the Spanish, not to mention the British gave out smallpox blankets during the Seven Year's War to crush the French Native Allies) Rather, I was pointing out that, unlike other genocides, most horrifically the Holocaust, the US was not engaging in a systematic extermination of the Native Americans or putting in place policies to completely wipe out their culture en masse to all of the nations. Rather, most of the Natives were already dead by the time the United States gained its independence, leaving a very sparsely populated continent with a series of scattered tribes that were in no shape to unify or go against it. I was pointing out how the US treated them more ethically than other empires or countries did historically given similar positions of power, such as Rome, which is often compared to the US because of it as a global Hegemony only rivaled during its height by the Han Chinese. We don't view the Romans conquering the tribes of Italy, Gaul, or destroying Carthage so utterly that nothing could grow on its soil because they sewed the soil with salt as we do the US which did nothing that compares to the scale and brutality the Romans committed to forge their empire. Especially because most of the death and destruction would have happened before the US became a nation, especially due to the mass death from disease.
That's demonstrably not true of all democracies. Ancient Athens, Rome, and the many other pre-Enlightenment republics of the world had no interest in universal suffrage or equality under the law. It is only because of the US's influence that so much of the modern world is built on Democracy because of its control over things like the UN, and its post-WWII rise as a global power that spread its values everywhere. Europe did have its share of influences from the Enlightenment in Britain and France, but most countries until very recently were still Monarchies over there, with Russia still having serfs and feudalism until a few decades before the first world war.
Finally, your nation of success is very skewed given that you ignore that there's plenty of failed societies that have arisen over the years all over Africa, Asia, Europe, etc. A nation like China, which you cite, is dependent on the US to buy its goods in order to keep its economy going as if the US was able to become completely self-sufficient, the Chinese's industries would collapse under their own weight. You must judge the success of nations relatively, and based on a myriad of factors, that, when you combine them all together, the US still is consistent excellent in due to the system in place. For instance, when you consider quality of life in the US compared to other countries and factor in the US's size, population, and wide array of cultures and geography that each have their own needs and drives, it's definitely fairly objective to say that the system is functioning, especially because most people have their nutritional needs met, mortality rates are low, and the US has been spear-heading innovation for the last century or so. (First to put a man on the moon is a pretty big accomplishment if you ask me, and a good indication of a functioning society if the government can afford to do that and its people are well-feed, experiencing less crime and poverty than any previous period in human history, etc.) I'd tell you to read a book called
Why Nations Fail, or
Guns, Germs, and Steel, but I don't think you'd be able to understand the arguments given how much you've missed most of my points.
