You may not be worried about the Saudis joining mBridge and BRICS but Trump sure as hell is. Trump also understand US manufacturers are fucked without Chinese supply chains...in particular but not only rare earths. The USA is not a capitalist economy it is a crony capitalist economy that is reliant upon its legacy domination of international institutions and protocols. The US government is beholden to Jewish bankers and military contractors. Without the seigniorage and rent from the USDs global domination of trade payments the US empire is swiftly insolvent.
