It's not just the people, it's the culture. Even USians that voted against Trump are marinating in a largely badly educated culture steeped in racism, unquestioning patriotism that often and overtly overflows into nationalism, a belief in exceptionalism, militarism and predatory capitalism. Fostering egotism, not necessarily stupidity but a hugely self-centered ignorance and aggressive distrust of a society that is overly individualist and a state that is corrupt.

Trump and his ilk are not the cause, but the symptom of this underlying sickness. And to heal that would take an enormous national effort to move away from money in politics, away from a national narrative of being better and more free, away from pride and towards rolling up your sleeves and going to work to fix things and where necessary reform not only society but how people are taught and think towards critical analysis and towards a more balanced approach between individual and societal freedoms.

An effort so enormous that I cannot fault the people who say this cannot be reformed peacefully and will likely result into a violent negotiation of the path forward. (Not that this would be preferred or even welcome, just that it is likely to either happen if, or be needed as a prerequisite that, meaningful change happens)

And the US is far from the only country that needs to change it's just the worst offender concerning pride in how fucked up they are AND as the cultural and military hegemon of the west their behavior affects others the most.
