@lovelylovely as an American, I actually spend quite a lot of time listening to international reporting about the US in part to see why they come to the perspective that they come to.
And reporting from outfits like the BBC on US events is actually pretty awful. It really constantly misses things like the differences between how the US government is set up versus parliamentary systems, how the parties function, how the voting system functions, and that's not even getting into details about what happens day to day.
As I listen to such international reports, it's not surprising at all that the US is baffling to people overseas: The reporting that so many overseas are being exposed to is just outright ignorant as to how things happen in this country.
People overseas are confused because so much overseas media reports stories that are confused.
