What you are describing seems to me to be a direct side effect of centralization. If the USA was just one country in a sea of two hundred roughly equal countries, the majority would quickly say "we will not allow that person to be a leader".

But since the USA is basically the world's richest and most powerful entity, the rest of the word begrudgingly tolerates the leader that has somehow come to power, simply because they need to keep the money flowing. There's no other spigot in town.

I disagree - we have a general principle around the world that a democratically elected "leader" is the result of the votes from the population and thus should be recognised at representing those people. The problem is when democracy is subverted with various methods such as gerrymandering districts, making it harder for some demographics to vote, removing voter registrations of certain demographics, misrepresentation of facts by the mainstream media etc.

It is a real problem with countries declaring "democratic elections" which are mere shams of democracy.
