Tom Clancy used this as the catalyst for one of his many techno war stories - something along the lines of “if you piss off your creditors they won’t give you any more money”. Think it was bear and dragon, the China Russia war. Debt is sold, and the purchaser’s willingness to buy sets the interest rate. And they don’t like uncertainty.

The us detached itself from the world after ww I and it seems to want to do it again. The tariffs might recapitulate the 30’s but that decade didn’t turn out well at all. So I hope the historical behaviour breaks down first.
