short answer - of course it will. the world doesn't revolve around america.
If the USD were to collapse (which it won't)
What makes you think that?
I do think the crisis is far from over but I don't think it will tear down the whole USD. A lot of market crashes happened already in recent history (since the twenties) and the USD is still standing strong. People need currencies and currently the whole western infrastructure is built on top of the USD.
Maybe you all would like to trade in chinese currency, controlled by the communist party in china?
I really don't know why that would be so much worse? Atleast they don't try to hide the torturing, media oppression, stasi like mass surveillance and true war objectives.
EDIT: Maybe there is some confusion about whether we are talking about the same country.
Here is an article on the country "US" I am talking about.
