The best explanation I’ve seen is the so called MarALago Accord[1]. I think the core thesis is that the US dollar and the US military being so core to all trade in the world had mad the US disadvantaged in terms of trade competitiveness. The accord is a set of goals/approaches to reduce that, theeeby making the US dollar more appealing for exports, other currencies less appealing.
