As an American I can confirm we are absolute trash right now and we're sealing our fate for at least a generation.
People the world over are going to spend the rest of their lives at the very least having a bad taste in their mouth when America is brought up. Things may "normalize" and regular trade agreements may resume, but trust is broken and that's long-term.
It's unbelievably depressing to watch from the inside. The shock of finding out that such a high percentage of your fellow citizens are stupid/racist/hateful is profound.
