> can her realistically prevent countries to do with each in a currency other than usd? yes, actually - he can prevent that by not tariffing countries and making trade with the united states as easy as possible. see:    brics is only a nothing burger because why would anyone do business with some aids-ridden corrupt shit hole like russia, a known patent thief like china, or a has-been like south africa that could fall apart any day (brazil is alright, hugs and kisses)?  america is bullied as a hegemony, but while their massive global success has been partially through military might - it's mostly been through lucrative economic exchanges. when you're friends with america you get rich. when you're friends with america you stop being a buckwheat millet eating shithole (usually). but if you're a russian or chinese you don't comprehend that trade can be used to benefit everyone involved, nor are you particularly interested in increasing quality of life or really any of those things since if people get too smart and well-paid they'll want to participate in the government. these countries have extractive ideas about commerce and trade is just a means to an end. how does the saying go? it's not enough to succeed, other's must fail as well?
