Most evidence shows the U.S. no longer benefits from the dollar as a global reserve currency. And lots of governments have currency boards or currencies they don’t control.
1. The currency board countries are very small players, mostly beaten to blue and also not all currency boards are tied to USD.
2. The bulk (I guess 90%+) of global lending is still in USD - a currency which the Fed can debase at will - as has been happening since 2008 and happened at a grande scale in 2020.
This brings only frustration and bitterness - the last two things you want in international relations, especially in the post-nuclear age soft-power days.
