internally, the united states is very chaotic and violent.
and the united states has caused a ton of chaos and violence throughout the world. arguably they're one of the main causes of instability in a lot of countries.
The US has made some questionable choices, but here I'm talking about not only the US, but Europe, Oceania, Japan, South Korea etc. As a European though I'm eternally grateful that the one country to become the global hegemon was the US. I don't think the world realizes how lucky it is. Might sound like a fanboy but there's plenty about the US I don't like, moved back home because of those things even, but you have to look at the bigger picture here.
