But the curious thing is, he's rude as hell to many of America's allies, as well as destructive of their relationships with the US (eg imposing tariffs). Americans cannot be surprised foreigners find him ridiculous and US politics toxic.
Along with Dubya, the world is crying out for the US to fix itself. It isn't just that Republicans are bad. It's that America produces Republicans and lets them get control. There's a huge issue that doesn't get addressed.
I suspect it doesn't get addressed because the US is unwilling to look hard for its own blemishes in the mirror. Too much of US identity is tethered to the conceit that it is a beacon for the whole world. At the moment it is in some ways more like a cancer (eg global warming, international trade, support of dictators).
