Let me just ask some broad questions.
What government should all humans live under?
Does it make sense, that humans should live under different governments?
Does it also make sense, to separate humans between arbitrary lines of property and nationalities?
Well, if we're talking about ideally (as impractical as we can imagine), all humans should be unified as one globally. Kind of like what John Lennon described in his song "Imagine." If all humans believed in it and went along with the principles therein, there probably wouldn't even be any need for government at all, let alone different governments.
Since such a thing is considered to be virtually impossible, ostensibly due to the failures of human nature and the inherent flaws of our species, then some sort of government is necessary. As far as what makes sense, government is seen as a practical necessity based on the circumstances a given body of people in a given land are facing.
When you suggest that we allow others to govern themselves, what does that really mean? Are they actually living as they want under a government like communism? Obviously, that's a bit rhetorical. There is no they in communism. People do not choose to be governed as communists. They are forced to be communists.
But who forces them to be communists? God? Aliens from outer space? Or is it "people"? If there are people who conceive and invent communism and actively choose it, then obviously
some people are choosing to be governed as communists, correct?
If we have a government of the people, by the people, and for the people - and if a majority of those people choose communism, then that's what they're going to have.
If we had to choose one nation to rule us all, what nation should that be? Of course, I'm setting up my own goal posts here but what if the Germans won WWII, is that good for the human race?
Well, if the Germans won WW2, and if they ruled the world and eliminated all the "non-Aryan" nationalities, then those who are remaining would be "white Aryans," and they would then be the entire human race (since there wouldn't be anyone else left). A few generations down the line, after all the victims have been dead, buried, and forgotten, what kind of life would the remainder of the human race have?
That's how they justified themselves. Despite how ugly and atrocious war and mass killings were, they considered it a worthy sacrifice to make in order to achieve what they foresaw as a peaceful, plentiful, idyllic society for their descendants in the "Thousand Year Reich."
Of course, the main drawback was in the means of achieving that goal, and they surprisingly found that most of the "non-Aryan" races didn't want to be eliminated and have their nations/cultures destroyed. They fought back and outnumbered the Germans, who were utterly defeated.
Such a goal of world conquest is often considered just as impossible as a peaceful transition to global cooperation and the unification of humanity as imagined by John Lennon.
But trying to convince all humans of all nations to voluntarily cooperate and unify with each other of their own free will seems far less messy, violent, and murderous than what the Nazis did. The communists wanted all the workers of the world to unite, not by force, but of their own free will.
The fact that so many people refused to cooperate with such a noble goal is how the communists ended up hitting snags and opposition. The communists apparently viewed their detractors as selfish, greedy, bourgeois - and that they were only thinking of themselves and not caring a whit about their fellow human.
Even to this day, many people see selfishness and greed as negative, immoral human qualities - and the more brazen it gets, the more infuriating it can be for a lot of people. Looking over human history, it can sometimes generate so much fury and rage as to lead some people to want to kill those who are selfish and greedy - or at least try to re-educate them to try to convince them that selfishness and greed are morally wrong.
Whether or not it's moral to kill those who are immoral is a judgment call.
We get caught up so easily on borders, race, sex, and individual traits that we easily forget that we're all human. We all deserve the best society that can be offered to us.
What's the best way to get people to care and show compassion for their fellow human, to treat them with dignity and respect them as equals, simply on the basis of the fact that they're human, regardless of any other factors?
